BRIDGE Technology: An Architecture Framework Enabling Smarter Control

<section id="isPasted"><h2>Understanding Underwater Navigation</h2><p>In the navigation of underwater environments, knowing your position is critical, yet traditional Global Positioning System (GPS) solutions are rendered ineffective due to the limitations of underwater signal propagation.</p><p>In such challenging conditions, Deep Trekker’s Remotely Operated Vehicles (ROVs), equipped with a suite of advanced sensors and navigation methods, offer a sophisticated alternative.</p><p>Underwater navigation presents unique challenges owing to the attenuation and distortion of signals underwater, necessitating the development of specialized techniques. Deep Trekker ROVs leverage a diverse &amp; robust sensor suite as well as sensor fusion algorithms to navigate in these complex environments. This article examines the complexities of underwater navigation, demonstrating the role of Inertial Measurement Units (IMU), Ultra-Short Baseline (USBL), Doppler Velocity Log (DVL), Dead Reckoning, and other cutting-edge technologies employed by Deep Trekker ROVs.</p></section><section><h2>Key Underwater Navigation Sensors</h2><p>ROVs integrate a comprehensive suite of advanced sensors and methodologies, each playing a crucial role in ensuring reliable underwater navigation. Below is an overview of key sensors</p><p><strong>Camera:</strong> Serving as the primary source of situational awareness, high-definition cameras provide operators with real-time video feeds. They facilitate easy maneuverability during inspections of underwater assets and structures, offering vital visual cues essential for navigation.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226099378-1721226099378.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><strong>Inertial Measurement Unit (IMU):</strong> Incorporating a compass, gyroscope, and accelerometer, the IMU tracks the ROV's orientation and motion in three-dimensional space. This data is necessary for stabilizing the vehicle and executing careful maneuvers.</p><p><strong>Pressure Sensor:</strong> Accurate depth measurement capabilities enable ROVs to maintain consistent altitude above the seabed, ensuring safe navigation and inspection operations. The depth / pressure is used to maintain a precise depth below the surface of the water column. The DVL also measures the altitude (vertical distance from the seabed).</p><p><strong>Doppler Velocity Log (DVL):</strong> By measuring changes in sound wave frequencies, DVL systems determine the ROV's speed, direction, and altitude relative to the seabed. This information is vital for maintaining course accuracy and executing dynamic maneuvers.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226094348-1721226094348.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></p><p><strong>Multibeam Imaging Sonar:</strong> Utilizing sound waves for real-time imaging, multibeam sonars offer detailed underwater visibility even in low or zero-visibility environments. They play a crucial role in navigation, object detection, and seabed mapping with exceptional resolution, serving as the primary visual aid when water clarity is compromised.</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226097757-1721226097757.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><p><strong>Ultra-Short Baseline (USBL):</strong> Integration with USBL enhances navigation accuracy and enables autonomous navigation and position holding in challenging underwater conditions.</p><p><strong>Dead Reckoning:</strong> Dead Reckoning is a fundamental navigation method to estimate position based on previously known position, velocity, and heading information. By continuously integrating sensor data and accounting for external factors such as current drift, Dead Reckoning algorithms enable ROVs to maintain correct position estimates over extended mission durations.</p><h2>USBL Integration: Achieving Underwater Navigation Precision</h2><p>The integration of USBL systems transforms underwater navigation, offering exceptional accuracy and reliability. By triangulating the ROV's position relative to surface transducers, USBL technology enables real-time mapping and localization underwater.</p><p>The seamless integration of USBL positioning enhances the capabilities of underwater ROVs, providing users with comprehensive navigation and mapping solutions tailored to diverse underwater applications.</p></section><section><p>USBL triangulation quality is not as accurate compared to GPS triangulation quality; however, the overall quality of USBL is improved through sensor fusion.</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226101337-1721226101337.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><h2>Exploring IMU Technology</h2><p>IMUs are integral components of underwater navigation systems, providing crucial data on an ROV's orientation and motion.</p><p>Let’s take a look at both FOG and MEMS based IMU systems.</p><h3>MEMS vs. FOG IMU: Choosing the Right Technology for Underwater Navigation</h3><p>In the world of underwater navigation, the selection of the appropriate IMU technology plays a crucial role in ensuring accurate positioning and stable control of ROVs. Two prevalent IMU technologies, Microelectromechanical Systems (MEMS) and Fiber Optic Gyroscope (FOG), offer distinct advantages and trade-offs, each suited to specific applications and operational requirements.</p><h3>MEMS IMU: Miniaturization and Cost-Efficiency</h3><p>MEMS IMUs are characterized by their compact size, low power consumption, and cost-effectiveness.</p><p>Leveraging microfabrication techniques, MEMS IMUs integrate miniature sensors, including accelerometers and gyroscopes, onto a single silicon chip. This miniaturization enables MEMS IMUs to be seamlessly integrated into compact ROV designs, offering enhanced maneuverability and operational flexibility.</p><p><a href="https://www.deeptrekker.com/shop/products/sensor-pod" target="_blank"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226108646-1721226108646.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></a></p><p>Furthermore, MEMS IMUs boast relatively lower production costs compared to their FOG counterparts, making them an attractive choice for budget-conscious projects and applications requiring mass deployment of underwater vehicles.</p><p>Despite their compact size and cost-effectiveness, MEMS IMUs deliver respectable performance in terms of accuracy and reliability, meeting the demands of many underwater navigation tasks.</p><p>One of the main drawbacks of MEMS is that they are less stable compared to FOG systems. MEMS systems usually rely on a compass to ensure heading stability. This fixes the heading stability issue while maintaining cost-effectiveness, however, this also means that MEMS systems tend to be susceptible to local magnetic distortions.</p><h3>FOG IMU: Precision and Stability at a Higher Cost</h3><p>In contrast, FOG IMUs offer exceptional precision and stability, making them well-suited for demanding underwater navigation applications that require more finite accuracy and long-term reliability. FOG IMUs utilize the principles of interferometry, where light waves traveling through a coiled fiber optic loop experience changes in phase due to rotation, allowing for accurate measurement of angular velocity.</p><p>The inherent stability and accuracy of FOG IMUs make them ideal for tasks such as underwater mapping, seabed surveying, and pipeline inspection, where positioning and motion tracking are critical. However, FOG IMUs typically command higher production costs and exhibit larger physical footprints compared to MEMS counterparts.</p><p>In addition to their cost, it’s important to note that FOG IMUs also require a significant amount of time to boot up and calibrate (approximately 15 minutes). During this time, the vehicle must be completely flat and stationary on solid ground, which makes deployment off of a boat problematic.</p><h3>Choosing the Right IMU for Your Application</h3><p>When selecting between MEMS and FOG IMUs for underwater navigation, it is necessary to consider the specific requirements of the intended application, including accuracy, cost constraints, operational conditions, and deployment scale. For projects prioritizing compactness, cost-efficiency, and versatility, MEMS IMUs offer an attractive solution, providing great performance for a wide range of underwater tasks.</p><p>On the other hand, applications demanding uncompromising precision and long-term stability may favor the superior performance offered by FOG IMUs, despite their higher cost and larger form factor.</p><p>By carefully evaluating the trade-offs between performance, cost, and operational requirements, teams can make informed decisions when selecting the most suitable IMU technology for their underwater navigation needs.</p><p>While MEMS IMUs excel in compactness and cost-efficiency, FOG IMUs offer unmatched precision and stability, catering to the diverse needs of underwater inspections, research, and industrial applications.</p><p>By understanding the strengths and limitations of each IMU technology, stakeholders can make informed decisions to optimize the performance and efficiency of their underwater navigation solutions.</p></section><section><h2>Dead Reckoning Techniques</h2><p>Dead Reckoning serves as a complementary method for underwater navigation, particularly in scenarios where external positioning systems may be unavailable or unreliable.</p><p>By continuously integrating IMU data with velocity and heading information, dead reckoning algorithms estimate the ROV's position based on its previous known location. Deep Trekker ROVs utilize Dead Reckoning techniques to maintain navigation accuracy in sub-sea GPS-denied environments.</p></section><section><h2>ROV Navigation With Sonar</h2><p>With the unique profile of acoustic interpretation, sonar systems can be very valuable when mounted with an ROV. Without sonar, the pilot of the ROV will have to rely on the visual relay of the objects and features through a camera. In low visibility environments, it might be hard to see with the range often being under a meter.</p><p>Sonar systems will drastically increase this range, allowing the pilot to detect objects from much further away. Instead of going over the seabed to find objects, the ROV can remain stationary and scan the entire environment. The pilot can then get an understanding of the area with the man-made objects, natural surfaces, and areas to ignore.</p></section><section><h2>Sensor Fusion: Enhancing Navigation Precision</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226111942-1721226111942.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii">The synergy of IMU, DVL, and other sensors through sensor fusion techniques enhances the accuracy and reliability of underwater navigation. By intelligently integrating data streams and compensating for sensor inaccuracies, ROVs achieve navigational precision and stability.<p>Sensor fusion algorithms optimize control responses, mitigate environmental disturbances, and enable autonomous operation, thereby streamlining underwater operations and inspection tasks.</p><p>Through continuous refinement and calibration, sensor fusion elevates the capabilities of Deep Trekker ROVs, ensuring seamless navigation even in dynamic underwater environments.</p></section><section><h2>Advanced Underwater Positioning Systems: A Comparative Analysis</h2><p>The classifications of positioning systems can be divided into three overarching tiers, each catering to specific requirements and budgets.</p><p>High-End Military Grade Solutions: "The high-end, military-grade solutions are typically FOG IMU-based, without the need for DVL integration, employing accelerometers and gyroscopes, albeit at a prohibitive cost," explains Nemanja Kliska, Deep Trekker Team Lead and Autonomy Systems Engineer.</p><p>These top-tier systems, typically priced between half a million to several million dollars, prioritize uncompromising accuracy and reliability. Utilizing FOG IMU-based technology, these systems, commonly found on military vessels and submarines, employ gyroscopes and accelerometers to achieve precise navigation without reliance on external sensors like DVL.</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226111248-1721226111248.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></p><p>AC Spark Plug Titan Inertial Measurement Unit</p><p><br></p><p><strong>High-End Civilian Systems:</strong> Positioned below military-grade solutions, high-end civilian systems offer advanced navigation capabilities at a relatively lower cost. Incorporating IMU or AHRS technology - comprising accelerometers, gyroscopes, and magnetometers - these systems ensure robust performance in various underwater environments. Moreover, some variants employ FOG systems to mitigate heading drift, enhancing positional accuracy.</p><p><strong>MEMS-based Systems:</strong> Representing the next tier, MEMS-based systems provide a cost-effective alternative with acceptable performance metrics. Integrating MEMS gyroscopes and accelerometers, these systems offer satisfactory accuracy under optimal conditions. However, they rely heavily on compass or magnetometer data and require continuous calibration to mitigate errors and environmental interference, and require the incorporation of DVL systems.</p></section><section><h2>Advancing Underwater Navigation with Deep Trekker ROVs</h2><p>In conclusion, the utilization of advanced sensors and positioning methods transforms underwater navigation with Deep Trekker ROVs.

MEMS vs FOG IMUs: Exploring Underwater Navigation Technology

<section id="isPasted"><h2>What is Dead Reckoning?</h2><p>Dead Reckoning navigation, also known as "deduced reckoning," relies on the principle of estimating the current position based on the last known position, velocity, and heading. It involves using the direction and speed of movement to calculate where you are now relative to where you were previously.</p><p>Dead Reckoning is particularly useful in scenarios where GPS signals are unreliable or unavailable, such as underwater environments where GPS signals cannot penetrate. This method has been integral to navigation, serving as a reliable means of orientation when other references are unavailable or unreliable.</p><p>“Dead reckoning is quickly becoming our new favorite way to operate ROVs and understand positioning of our vehicles,” says Sam Macdonald, President of Deep Trekker. “Setting up USBL or flying completely blind is hard for us as users and our customers. We want to make the piloting experience as easy as possible.”</p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgxMTkzLTE3MjAwMjQ5ODExOTMucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></section><section><h2>The Significance of Dead Reckoning in Underwater Navigation?</h2><p>There are numerous challenges with underwater navigation. Unlike terrestrial or aerial navigation, where landmarks or satellites provide reference points, underwater environments offer minimal visual cues.</p><p>Factors such as fluctuating ocean currents, variations in water density, and unpredictable underwater terrain further complicate the navigation challenges. Without reliable navigation, underwater vehicles run the risk of veering off course, potentially endangering both the vehicle itself and any onboard equipment or personnel.</p><p>Navigating underwater environments poses distinct challenges, requiring specialized techniques like Dead Reckoning to ensure safe and efficient operations. Underwater navigation lacks prominent landmarks or GPS signals, making reliance on Dead Reckoning a key method for accurate positioning.</p><p>This method, reminiscent of long-standing historical navigation practices, becomes particularly important in underwater operations where traditional navigation aids like landmarks or celestial bodies are inaccessible.</p><p>Understanding and implementing Dead Reckoning involves leveraging advanced sensors and algorithms to mitigate inherent challenges, such as sensor inaccuracies and cumulative drift. As technology progresses, optimizing Dead Reckoning capabilities becomes pivotal for enhancing underwater navigation.</p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgwNjMzLTE3MjAwMjQ5ODA2MzMucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><p>Deep Trekker’s PIVOT and REVOLUTION ROVs can operate with Dead Reckoning utilizing an upgraded inertial measurement unit (IMU) and Doppler Velocity Log (DVL) sensor combined with our BRIDGE software. The goal of these ROV systems is to simplify the experience so customers can input an initial position and then get in the water and go. That doesn’t mean there aren’t any best practices you can leverage to optimize your experience! Below are some tips and tricks to assist with your ROV piloting.</p><h3>The 6 Rules of Dead Reckoning</h3><p>The <a href="https://www.usna.edu/Sailing/_files/documents/2019_OSTS_Documents/Navigation_101_05MAR19.pdf" target="_blank" data-lf-fd-inspected-kn9eq4roawkarlvp="true">"6 Rules of Dead Reckoning"</a> are guidelines used in navigation, particularly in maritime and aviation contexts, to ensure that an estimated position (Dead Reckoning position) remains as accurate as possible throughout a journey. These rules help navigators keep track of their position and make necessary adjustments. To effectively maintain the vessel’s Dead Reckoning position, the navigator should follow theses 6 rules:</p><p><strong>1. Regular Position Updates:</strong> Update the Dead Reckoning position at regular intervals, typically every hour on the hour. This helps account for changes in speed, course, and environmental conditions that may affect the estimated position. This periodic recalibration is essential for compensating for sensor drift, especially prevalent in underwater technology. Manual recalibration or resurfacing with GPS helps in correcting any deviations and maintaining accuracy.</p><p><strong>2. Adjustment after course changes:</strong> Following any alteration in the vehicle's course, promptly update the Dead Reckoning position to accommodate the modified trajectory. Utilize additional sensors such as a Doppler Velocity Log (DVL) sensor that tracks changes from the seafloor for underwater vehicles or Inertial Measurement Unit (IMU) sensors that track vehicle orientation changes to ensure alignment with the intended route.</p><p><strong>3. Adjustment after speed changes:</strong> Whenever there is a change in the vehicle's speed, it's also important to update the Dead Reckoning position immediately to help ensure that the calculated position remains accurate, considering the altered velocity.</p><p><strong>4. After every fix or running fix:</strong> A "fix" is a position obtained from external references, such as celestial observations, GPS, or terrestrial landmarks. A "running fix" is an ongoing series of fixes that helps refine the Dead Reckoning position. After obtaining either a fix or running fix, the navigator should update the Dead Reckoning position to incorporate this more accurate position information. In the case of an ROV, running fixes could be a GPS mounted on top that gets a fix whenever surfacing or a USBL getting pings during its dive. A fix also could be from a manual GPS input by the user when the ROV surfaces.</p><p><strong>5. After plotting a single line of position:</strong> A line of position is a navigational line that represents the possible positions of a vehicle at a specific time. It is determined using observations of celestial bodies, radar ranges, or other means. After plotting a single line of position, the navigator should update the Dead Reckoning position to account for this new piece of positional data.</p><p><strong>6. DR twice and label with Course and Speed:</strong> After every fix or running fix (repeated for emphasis). Reiterating the importance of updating the Dead Reckoning position after obtaining a fix or running fix. This ensures that the Dead Reckoning position continuously incorporates the most accurate position information available.</p><p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgxMDk5LTE3MjAwMjQ5ODEwOTkucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></p><p>Fig. 1: Example of a Mercator chart style Universal Plotting Sheet used by the Navy for navigation.</p></section><section><h2>Integration of Dead Reckoning with Other Navigation Techniques</h2><p>While Dead Reckoning serves as a foundational navigation method and can be a standalone tracking method, its effectiveness can be amplified through integration with complementary techniques. By combining Dead Reckoning with other navigation methods, such as acoustic positioning systems and satellite-based navigation, navigators can enhance positional accuracy and resilience to environmental challenges.</p><p>Acoustic positioning systems, such as Ultra-Short Baseline (USBL), Short Baseline (SBL), and Long Baseline (LBL), provide precise localization capabilities by measuring the time of flight of acoustic signals between transponders and the vehicle. By incorporating acoustic position updates into Dead Reckoning calculations, navigators can refine their estimated positions and mitigate drift accumulation.</p><p>Similarly, satellite-based navigation systems, including GPS and GNSS (Global Navigation Satellite System), offer helpful external references for validating Dead Reckoning positions. While traditional GPS signals may be unavailable underwater, emerging technologies such as underwater GPS and Differential GNSS (DGNSS) enable precise positioning in submerged environments. By cross-referencing Dead Reckoning positions with satellite-derived fixes, navigators can ensure greater accuracy and reliability in their navigational estimates.</p><p>Furthermore, fusion algorithms, such as Deep Trekker’s Sensor Fusion algorithms, that integrate data from multiple sensors and navigation methods can optimize positional accuracy and robustness. By leveraging the strengths of each technique while compensating for their respective limitations, fusion algorithms provide a comprehensive solution for underwater navigation challenges.</p></section><section><h2>The Role of Sensors in Dead Reckoning</h2><p>Sensors play a significant role in Dead Reckoning by providing essential data inputs for calculating position estimates. Particularly in underwater navigation scenarios with ROVs, characterized by limited visual references, sensors serve as the eyes and ears of the vehicle, capturing crucial information about its movement and surroundings.</p><p>Various types of sensors are employed to track different aspects of the vehicle's motion. Doppler Velocity Log (DVL) sensors measure the vehicle's velocity relative to the seafloor by analyzing Doppler shifts in acoustic signals. This data is integral for calculating speed and direction changes, forming the basis of Dead Reckoning calculations. Additionally, Inertial Measurement Unit (IMU) sensors track the vehicle's orientation and angular velocity, providing necessary inputs for maintaining course accuracy.</p><p>Advancements in sensor technology, such as miniaturization and improved accuracy, have also enabled more sophisticated Dead Reckoning systems. MEMS (Micro-Electro-Mechanical Systems) sensors, characterized by their compact size and low power consumption, have become increasingly prevalent, offering a perfect blend of performance and efficiency for underwater navigation applications.</p><p>By leveraging the capabilities of these sensors, Dead Reckoning systems can navigate with improved precision, overcoming the challenges posed by the underwater environment and enabling safer and more efficient navigation.</p></section><section><h2>Understanding the Limitations of Dead Reckoning</h2><p>While Dead Reckoning serves as a valuable navigation technique, it is not without its challenges and limitations. Understanding these factors is important for mitigating risks and optimizing the performance of Dead Reckoning systems.</p><p>One notable challenge is the accumulation of errors over time, often referred to as "dead reckoning drift". This drift can arise from sensor inaccuracies, environmental disturbances, and uncertainties in the vehicle's dynamics. It’s important to note that these errors can compound, leading to considerable deviations from the true position, which is why periodic updates and recalibrations are so critical for maintaining accurate positional data.</p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgxMTM4LTE3MjAwMjQ5ODExMzgucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><p>Dead Reckoning is also susceptible to disruptions caused by external factors such as ocean currents, water density variations, and submerged obstacles. These dynamic environmental conditions can impede the vehicle's trajectory, making it challenging to maintain accurate position estimates.</p><p>Additionally, reliance solely on Dead Reckoning in scenarios with limited external references, amplifies the risk of navigation errors. In such cases, a single miscalculation or sensor malfunction could lead to navigation errors with potentially serious consequences.</p><p>Addressing these challenges requires a multi-faceted approach, combining robust sensor technologies, advanced algorithms, and strategic operational practices. By continually refining Dead Reckoning systems and incorporating complementary navigation techniques, such as Deep Trekker’s Sensor Fusion algorithms, operators can navigate with greater confidence and reliability in challenging underwater environments.</p></section><section><h2>Dead Reckoning Empowering ROV Operations</h2><p>Dead Reckoning is a fundamental navigation technique, offering a practical solution for navigating the intricate and often unpredictable underwater terrains encountered by ROVs (remotely operated vehicles) used for underwater operations.</p></section><section><p>By leveraging known parameters and updating positions in responses to changes in course and speed, Dead Reckoning provides a practical means of estimating positions where traditional navigation aids may be unavailable or impractical.</p><p>Its integration with complementary technologies such as acoustic positioning systems enhances its accuracy and robustness, making it a valuable tool for underwater operations and inspection tasks.</p><p>As advancements in sensor technology and navigation algorithms continue, Dead Reckoning holds promise as a dependable navigation technique for conducting essential vessel inspections with improved precision and efficiency, even in challenging underwater environments.&nbsp;</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1720025957910-IMG_6444.png" style="width: 100%px;" class="fr-fic fr-dib"></p></section><section><h2>The Deep Trekker Advantage</h2><p>Deep Trekker ROVs, engineered with rugged industrial-grade materials, are designed for versatility and durability.

Drones are integral to military operations globally, especially in high-risk environments where manned flight is impractical. Learn how to integrate sensors into these devices properly. 

Drone PCBAs: Tackling Sensor Integration for Defense & Beyond

<p id="isPasted">InDro Robotics – as always – has been hard at work on innovative new products. And we’re particularly proud of our latest accomplishment: The InDro Controller.</p><p>It’s an all-in-one solution for operating virtually any type of robot from a highly secure console. It’s completely robot-agnostic, very easy to use – and exceedingly powerful. We’ll get into the details as we go, but first let’s hear from Front End Developer RJ Bundy with an elevator pitch.</p><p>“It’s an all-in-one data visualization, robot management and robot control software,” he says. “Whether&nbsp;you’re a student first learning how to use a robot or you’re a commercial giant, you’d be able to manage and maintain all of your robots.”</p><p>He’s not exaggerating. We walked through a demo of this system recently, with Head of R&amp;D Sales Luke Corbeth at the controls and Bundy explaining the various features. We connected remotely with one of our InDro robots. The software immediately detected all of the sensors on the platform, offering up a display of windows showing the data they were collecting with minimal latency.</p><p>“It can handle all sorts of data,” says Bundy. “It doesn’t matter if the robot has standard or custom sensors, InDro Controller can automatically detect and visualize them. For example, if you added a radar unit to an existing robot, the system will pick up on that immediately.”</p><p>Of course, it has teleoperation. Missions can be run manually or autonomously (with InDro’s autonomy stack loaded onto any ROS-based robot).</p><p>“We have a GPS-based autonomy – which is better for outdoors – and then we have a SLAM- (Simultaneous Localisation and Mapping) based autonomy which is ideal for indoors,” says Corbeth.</p><p>And while InDro Controller has very complex capabilities, it’s a snap to use.</p><p>“Once it’s set up, it’s pretty straightforward to initiate the mission. Even someone without any robotics knowledge could do it,” he adds.</p><p><em>Below: The Pilot View mode in InDro Controller. Data from any desired sensors is displayed with minimal latency via a highly secure connection.</em><em><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE4MjkyNzQ3Mzk1LVBpbG90LVZpZXcucG5nIGNvcHkuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib" alt="Teleoperation Pilot View"></em></p><h3 id="isPasted">Highly Secure</h3><p>Regardless of whether you’re a startup, researcher, or a major corporation collecting sensitive data – security is important.&nbsp;InDro Controller has been built with that in mind.</p><p>“We’ve created an interface that makes it very hard for a third party to intercept any of those commands or the data coming from the robot to you.”</p><p>Though the person controlling the robot is the primary login, others with a secure login can also monitor the missions remotely from anywhere in the world. The software can store as many repeatable missions as you can throw at it, and you can initiate a previously stored mission with a single click.</p><h3><br></h3><h3>Mission Planning</h3><p>Mission planning could not be simpler.</p><p>For the first mission, the pilot would manually control the robot. InDro Controller uses an Xbox controller plugged into your computer for intuitive operation (though other options are available). All buttons on the Xbox device can be quickly mapped to carry out specific functions.</p><p>InDro Controller tracks everything you’ve done – and we mean everything – and saves it as a repeatable autonomous mission.</p><p>“If you manually drive the robot somewhere, it will remember it’s been there and it’ll be able to go back, follow that same path every time. It will also remember to carry out any specific actions you’ve taken at those points of interest, including camera angles, zoom, etc.” says Bundy.</p><p>The mission planner also automatically loads a map to locate your robot (you also have the option of satellite view), so you can monitor exactly where it is on any given mission.</p><p>And, of course, it can do this for an entire fleet of robots.</p><p><em>Below: InDro Controller shows Points of Interest – which can be repeated with saved missions</em><em><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE4MjkyODA1NzE1LUF1dG9ub215LUdob3N0cy5wbmcgY29weS5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 100%px;" class="fr-fic fr-dib"></em><br></p><h3 id="isPasted">Highly Customizable</h3><p>InDro Controller has been designed to allow users to easily customize the user interface for any robot, any mission, and any dashboard view. Multiple streams of data, including upload and download speeds, battery levels and overall robot health are available at a glance. Oh, and did we mention it also works with third-party autonomy stacks?</p><p>“The dashboard, the cameras, the heads up display on the autonomous missions – those all can be customized,” says Bundy. “We’re also adding other personal user customizations, like a light and dark mode, metric conversion, schedule missions – all the kinds of features you could want.”</p><p>InDro Controller already works exceptionally well. But – as with all of our R&amp;D projects – it will continually be refined with additional features and functionality.</p><p>“We’re heavily invested in continuously improving the software,” says Corbeth. “So regardless of which version you’re shipped, know that this is something that InDro Robotics is constantly developing and improving with client feedback in mind to ultimately provide the best mission planning, teleoperations and development software tool in the robotics industry.”</p><p>Speaking of versions, there’s a simpler version of InDro Controller – which does not have the autonomy features – already being used for missions in the academic world. Feedback has been excellent.</p><p>“Users tell us they find InDro Controller Lite exceedingly powerful, but also very simple to use. That was exactly our goal in developing this product,” says Corbeth.</p><p><span dir="ltr">Academics and corporate innovation groups could take advantage of the Lite version, while the Industrial package is intended for solving more complex problems in an industrial environment.</span></p><p>&nbsp;</p><h3>Satisfying R&amp;D</h3><p>For Front End Developer Bundy, who oversaw this project with support from other engineering staff, it’s been a hugely satisfying – and challenging – project.</p><p>“A lot of the customization features were pretty difficult because it has to be robust and dynamic, which is always tough,” he says. “This is a relatively complicated application and I’ve managed to put together something pretty nice and functional – and it will only get better. “I’ve had a bunch of other help, but putting together the UI for InDro Controller has been, and continues to be, highly satisfying.”</p><p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE4MjkyOTIxNTg4LUFkbWluLnBuZyBjb3B5LmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 100%px;" class="fr-fic fr-dib"></p><h3 id="isPasted">InDro's Take</h3><p>We’re obviously excited about InDro Controller. And we’re particularly excited because we have a forthcoming piece of hardware – the InDro Module. It’s a small box with a lot of brains that can be added to any robot to increase functionality and enable the seamless addition of sensors and other modifications (as well as pre-loaded autonomy stack and ROS drivers). We’ll have more on that soon, but it’s the perfect match for InDro Controller for users with complex requirements.</p><p>For the moment, we’re looking forward to putting both the Lite and Industrial versions into the hands of clients.</p><p>“When we first began remote teleoperation several years ago, we relied on third-party software as the UI,” says InDro Robotics CEO Philip Reece. “But we found it wasn’t powerful or customizable enough for our needs. It also required that we have our own autonomy stack – and we did – but many clients do not. InDro Controller comes with our proprietary autonomy stacks for both outdoor and GPS-denied locations. And, as noted previously, this is a long-term project, where even early adopters can be assured the package will be continuously refined with additional features.”</p><p>Word has already been spreading in the R&amp;D and commercial fields about this product, and the feedback from those using the Lite version has been outstanding.

Enhancing Diver Safety: The Vital Role of ROVs in Commercial Diving

<section id="isPasted"><h2>Chapman Marine's Mission: Safeguarding Critical Infrastructure Below the Surface</h2><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/6BEr6SgPsMMp32IVs2QRJB/5b94431418dd1547136c90fc4e0f152a/image4.jpg" alt="chapman dam" class="fr-fic fr-dii"></p><p>Chapman Marine specializes in underwater inspections of critical infrastructure such as dams, power plants, and raw water intakes. Their primary goal is to identify and address issues before they escalate, ensuring the safety and reliability of these structures. Prior to incorporating ROVs, the company primarily relied on dive teams to gather critical information about underwater conditions. Now, they bring their Deep Trekker DTG3 and PIVOT ROVs to every job.</p></section><section><h2>Enhancing Safety and Efficiency in Underwater Inspections: The Role of ROVs at Chapman Marine Inc.</h2><p>Chapman Marine Inc., one of Texas’ trusted commercial dive and underwater construction companies, has revolutionized the field of underwater inspections by incorporating Remotely Operated Vehicles (ROVs) into their routine operations. In this case study, we will explore how Chapman Marine utilizes ROVs to enhance safety and efficiency during pre-job, routine, and emergency inspections. By doing so, they have not only reduced costs but also improved the quality of deliverables and safety for their team and customers.</p></section><section><h2>The Challenge of Underwater Inspections</h2><p>Philip Wolfe, General Manager at Chapman Marine, highlighted a recurring challenge in their operations: "We get the information that there's a problem down there, we know we've got an issue, but we don't know what it is."</p><p>Often, their team receives limited information about underwater issues, making it difficult to assess risks accurately. This lack of clarity poses a significant safety hazard for divers. Ultimately, the ROVs are much faster, safer, and easier to deploy than a diver.</p></section><section><h2>The Solution: Leveraging ROVs for Comprehensive Underwater Inspections</h2><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/2HlhtDflcr3ceNAxZXkicZ/8c6472960bb03f32ab1481c92057b8a9/image2.jpg" alt="Deep Trekker DTG3 ROV and tether reel package" class="fr-fic fr-dii"></p><p>Deep Trekker DTG3 ROV and tether reel package</p><h3>A Closer Look Before the Dive: ROVs Enhancing Safety in Pre-Job Inspections</h3><p>Before diving into the water, the team uses the limited information received from the customer to develop an initial understanding of the situation. This helps them gauge the safety risks involved.</p><p>“We use the ROVs to develop an understanding before we put divers in, to help us understand the safety risk before getting in the water,” Wolfe explains.</p><h3>Streamlining Routine Inspections: ROVs' Efficiency in Action</h3><p>ROVs are deployed for routine inspections, especially in confined spaces or areas requiring penetration. These inspections are completed in a fraction of the time it would take a dive crew, saving both time and resources.</p><p>“In some circumstances,” says Wolfe, “we use the ROV as the primary solution for certain inspections in areas where there's confined space or where we have to go into pipes or something like that, where it would take an entire day and a large crew to load out just to do the inspection, and we can do it in a few hours with the ROV and get the information that we need.”</p><h3>Responding Swiftly to Emergencies: ROVs in Critical Situations</h3><p>In emergency situations where immediate action is required, ROVs provide essential situational awareness. It’s dangerous to put divers into a situation where hazards aren’t entirely identified. Divers can be exposed to unknown dangers, making ROVs invaluable in understanding the situation better.</p><p>“We won't know all the safety issues. The ROVS help to develop the situation and we're often able to back off the urgency a little bit to say, ‘Here's the video. Here's what we understand. This is what we see is going on’. Then we pass that off to engineers, and make some recommendations so that they can develop that situation. So that's helpful for us and we're able to satisfy that gap in understanding in an emergency that often happens. It makes owners very uncomfortable, not knowing what's going on, and they want it fixed yesterday. So, it gives us some time to develop a better plan and then get out there and get after it.”</p><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/2K5gmK7Ut4m7JK9qzINpgk/28dad4a5c6f8865d5f7246557bedf273/image1.jpg" alt="chapman case study dam" class="fr-fic fr-dii"></p></section><section><h2>ROVs vs. Tripod Mounted Sonar: A Paradigm Shift in Underwater Inspections</h2><p>Wolfe explained their preference for ROVs over a tripod mounted sonar (the current standard in the Gulf of Mexico for the oil industry that's used offshore when mapping and inspecting underwater assets), emphasizing the quick access ROVs offered to inspection sites. Tripod mounted sonar systems, while capable of producing high-quality images, required additional equipment and were less versatile.</p><p>“So, that was why we went with the ROV versus just a tripod mounted sonar, because of its very quick access to the site, where the tripod mounted sonar requires additional equipment to get there because it's not mounted to anything. It's a tripod, you need a boat and crew, you drop it down, and it sits on the bottom. You get a beautiful picture, but to get that beautiful picture, you have to have all that other stuff, and you have to have access to that point,” Wolfe illustrated.</p><p>“The limitations of a tripod mounted sonar is that it's not attached to an ROV, that it's not a two-man crew, and you have to have a boat. If you want GPS, you have to have that receiver attached to a boat. You have to do all this setup, which any GPS is going to require. I can't take a tripod mounted sonar with two guys and go 400 feet away from the shoreline when there's an issue on an intake or a dam or something. We need to have a place to launch, and all of these things that require additional equipment - which we have, but, It takes longer, it's more expensive, and a lot of times we just don't have direct access to the water - unless you're bringing ladders or you're doing a heck of a lot of work to get down there. If you're gonna do all that work, you might as well put a diver in the water.”</p></section><section><h2>ROVs in Action: Unveiling the Triad of Safety, Efficiency, and Quality</h2><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/740BJyCwuL4rDJcIdUIoo3/4c65a9c661ec75462cc06cfc9e703197/image3.jpg" alt="pelican case chapman " class="fr-fic fr-dii"></p><p>Chapman Marine has experienced numerous benefits since incorporating ROVs into their operations:</p><h3>Safeguarding Lives and Insights: How ROVs Prioritize Safety</h3><p>ROVs significantly reduce the risks associated with underwater inspections. Divers are no longer exposed to unidentified hazards, ensuring the overall safety of the team. “Anytime a diver enters without visibility, they are exposed to a risk that they don’t need to be if we run an ROV.”</p><h3>ROVs: The Turbocharged Engines of Inspection Efficiency</h3><p>Routine inspections that once took a full day to mobilize and deploy now require just a few hours with an ROV pilot, resulting in substantial time and cost savings.</p><h3>Delivering Clarity: ROVs and High-Quality Customer Communication</h3><p>ROVs provide high-quality video footage that can be shared directly with customers. This not only improves situational awareness but also allows customers to identify issues firsthand. “Visualization is the most important part of analysis,” explains Wolfe.</p><h3>Comprehensive Reporting: The Cornerstone of Effective Inspections</h3><p>After every inspection, whether performed by ROVs or divers, Chapman Marine produces comprehensive reports with videos, pictures, and descriptions of the work performed, and issues recommendations.</p><p>“When you're looking at the reports that we're putting together, what is good to decision makers, you're talking about the highest echelon of whatever organization that we're working for, and sending them a link to a video. They're not watching the video. They want a one to two page report that has a picture with a description. When you look at the executive level of making decisions on a project that we're working on, that's the type of report that we put together. It needs to be simple and very clear: ‘Here is what it looks like. Here's what your problem is.’ It is very helpful that the ROVs make producing reports very easy.”</p><h2>A New Era of Collaboration: ROVs Enhancing Customer Engagement</h2><p>Chapman Marine recognizes the importance of involving their customers throughout the inspection process. By utilizing ROVs, they can have their customer's eyes directly on live ROV surveys, aiding in issue identification. This customer-centric approach improves communication and helps solve problems more effectively. Previously, they had divers entering low visibility environments with regular cameras, or describing the situation for post inspection with hand drawings.</p><p>“The customer knows the original problem better than the divers. With an ROV video, we can have their eyes directly on the live ROV survey and can better identify issues rather than relying on diver descriptions. With ROVs we can get there fast, get the information, and get it in front of more eyes, quicker, to better solve the problem.”</p></section><section><h2>Deep Trekker: The Game-Changer in Underwater Inspections</h2><p><img data-fr-image-pasted="true" src="https://downloads.ctfassets.net/kzewhs8e6cvu/4H4NjDluiIL0HzoHj9U7RF/0aaf965ab8e7fe2b67793651ffd272ac/REV_Standalone.png" alt="REVOLUTION at Pier" class="fr-fic fr-dii"></p><p>transforming their approach to safety, efficiency, and customer satisfaction. ROVs have become indispensable tools that not only reduce costs but also enhance the quality of deliverables and the overall safety of their team. As Philip Wolfe succinctly puts it, "It's all about how to tell the customer what is happening," and ROVs have become their most valuable means of communication in the underwater inspection field.</p><p>When asked what he likes most about utilizing the Deep Trekker ROVs:</p><p>“Previous ROVs we have used required a lot of set up and programming that we just don’t have time for. With a Deep Trekker, I can plug it in and it’s ready to go, you do all the updates, and I can give it to somebody, give them some training, and then they can go out and execute.”</p><blockquote><p>It's not a science project every time we try to pass it off to somebody.</p></blockquote><p>So that's really what I'm looking for. I don't need a project. I've got enough projects. I just need something where I can take this and put it in the water now. I understand it takes work, there's a little bit of work, like building a report takes work, but there's different levels of work and there's a threshold at which I'm willing to go up to. But once it surpasses that threshold, it's just too much for us because it's too time consuming," explains Wolfe.</p><p>When asked why he stays with Deep Trekker:</p><p>“So, I will tell you, customer service for me is big. We're willing to pay a little bit more to have customer service because, in the end, that means saving time and money for us when we run into an issue - and that goes across everything that we do, whether we're buying a new engine for our boats, or whatever it is. We changed manufacturers for all the motors on our boats because there wasn't service for them. They're great motors, but no service doesn't help us. That's important, and I do like the updates. Deep Trekker just adds some additional capability to the ROV that you already have, to increase the functionality of the system. It’s awesome.”</p><h2>Exploring the Deep Trekker Family of ROVs</h2><p><img data-fr-image-pasted="true" src="https://downloads.ctfassets.net/kzewhs8e6cvu/5qr0cwf5B052kcAgyjmAH2/b3b3864cdf537fa3f718ccf8b045906e/Group_Glamor_Shot_2.png" alt="Family photo Group Glamor Shot 2" class="fr-fic fr-dii"></p><p>From left to right: DTG3, PHOTON, PIVOT, REVOLUTION</p><p>Deep Trekker ROVs present the ideal solution for conducting inspections of dams, infrastructure, and intake systems.

<h1 id="isPasted"><br></h1><section><p>When you hear the word “drone,” you likely imagine an airborne device the size of a hat box that uses propellers to fly and is controlled remotely by someone in the immediate vicinity, perhaps in a park or another open area. Recreational drones like these have become increasingly popular in recent years.</p><p>But if you expand your definition of drones to include all unmanned aerial vehicles (UAVs), ranging from long-range drones used in military applications, to transport vehicles, to insect-sized drones, their potential applications expand exponentially. Imagine commercial airliners without pilots, drones capable of transporting shipping containers like those now delivered by trucks and ships, or even tiny, dexterous drones that fly into narrow gaps like insects.</p><p>While there are many obstacles for developers to overcome before these innovations can become a reality, the technology is evolving quickly – much faster than you might expect. This blog discusses where the technology currently stands and where it may go.</p><h2></h2><h3>High-Capacity Drones: Autonomy and Engine Innovations</h3><p>Scaling up drones to carry larger payloads, fly at higher altitudes, and travel greater distances presents major challenges for developers. Currently, semi- and fully autonomous large-scale drones (classified as UAVs that can carry a payload of greater than 1320 pounds and operate at altitudes greater than 18,000 feet) are most commonly implemented by military organizations to replace aircraft piloted by human operators.</p><p>Unlike smaller counterparts that rely on electric motors, larger drones use more robust internal combustion or jet engines. Not just a matter of size scaling, this means enhanced efficiency, reduced weight, and optimized fuel consumption, while also delivering precision control crucial in moving large loads.</p><p>By removing the human pilot and the various systems needed to support him, most large-scale drones are lighter and are usually built from lighter materials like plastics or carbon fibers. This increases the range of the vehicle. It can also reduce engine weight without compromising strength.</p><p>This is especially true for high-altitude long-endurance (HALE) drones. HALE drones must stay airborne for extended periods, sometimes days, at various altitudes and temperatures, and are often solar-powered. They are ideally suited for reconnaissance. In 2021, the U.S. Forest Service began testing HALE drones to locate and fight wildfires.</p><p>However, UAVs that operate at higher altitudes have more difficulty dissipating heat in the thinner atmosphere where they fly. <a href="https://www.macrofab.com/blog/overview-pcba-manufacturing-processes-technologies/" target="_blank">Printed circuit boards</a> for larger UAVs require additional heat transfer and use additional metal to connect to heat sinks to maximize performance at higher altitudes. This must be taken into consideration at the design stage. Simulating heat generation, flow, and dissipation in the development process is a valuable tool for these types of designs.</p><p>In terms of operational control, remotely piloted ICE (internal combustion engine) or jet aircraft aren’t significantly different from their traditional onboard piloted counterparts. A human operator guides the drone from a station with controls and monitors that are similar to the ones in airplane cockpits while cameras and radar-based imaging systems provide the visuals.</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1714573625993-1714573625993.png" alt="Drone carrying package" class="fr-fic fr-dii"><p>“Flying cars,” or “air taxis,” are already a reality, with China approving the first self-driving air taxi late in 2023. <a href="https://www.faa.gov/air-taxis" target="_blank">Similar air taxis are being planned in the USA</a>, though they will initially require a pilot on board for safety.</p><p>However, a significant hurdle in designing UAVs for human transportation or valuable cargo lies in bridging the information gap. While current sensors can track weather conditions, altitude, and airspeed, they cannot do so with the speed and sensitivity necessary. Onboard pilots can sense subtle changes in an aircraft’s behavior intuitively, a nuance challenging to replicate with sensors. By 2030, 6G wireless networks should significantly alleviate this issue by enabling ultra-low latency and improved data reliability, enhancing sensor responsiveness.</p><p>Lastly, many UAVs today boast semi-autonomous features like the ability to return to their starting point unaided. Autonomous or semi-autonomous flight software must be capable of dynamically adjusting flight paths in response to changing conditions, akin to how commercial airline pilots maneuver to avoid turbulence. This capability underscores the ongoing evolution and increasing sophistication of UAV technology in adapting to complex operational environments.</p><h2></h2><h3>Compact Drone Engineering: Revolutionizing Small-Scale UAVs</h3><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1714573626104-1714573626104.png" alt="Compact drone engineering" class="fr-fic fr-dii"><p>Every drone, from super large to shoe-box sized, relies on motors or engines to propel itself. In contrast to making drones larger, which requires increasing their power while reducing their overall weight, making them smaller necessitates removing motors altogether.</p><p>Using actuators to mimic how an insect flaps its wings plays a role in “micro drone” design. Early versions of this technology used ceramic materials to conduct and store electricity, but their inherent fragility made them unsuitable for repeated use.</p><p>The most recent innovations implement soft actuators composed of rubber cylinders surrounded by carbon nanotubes. Applying voltage causes the rubber cylinders to expand and contract repetitively and at high frequency (as much as 500 times per second), causing the drone “wings” to flap up and down.</p><p>These tiny drones, with their soft actuators, are resilient and capable of withstanding mid-air collisions, making them suitable for various tasks, including agricultural monitoring and pollination. Future uses may include structural inspection, search and rescue, surveillance, and data collection.</p><p><a href="https://www.macrofab.com/prototyping/" target="_blank">PCB designs</a> for smaller, more malleable devices have to consider factors like weight, rigidity, and resistance to impact and vibration. As in the case of larger UAVs, software simulation to test mechanical reliability in smaller UAVs is a valuable development tool.</p><h2></h2><h3>The Future of UAVs Great and Small</h3><p>In the future, UAV commercial passenger flights or large material transport using entirely autonomous flights still have some design challenges to overcome. Regulations, however, are more likely to hinder their long-term progress. Like self-driving cars, the adjustment period will require examining and discussing the risks and rationale of flying without a human pilot, with safety always taking precedence.</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1714573626041-1714573626041.png" alt="Uav future" class="fr-fic fr-dii"><p>On a smaller scale, however, UAVs may have more immediate practical applications. With micro drones with cameras that relay images back to a human operator, inspecting intricate mechanisms is possible in small spaces that are otherwise impossible to reach without dismantling the entire mechanism, such as industrial motors or airplane engines. Drones can even be used during natural disasters to locate missing or injured people who cannot be reached by rescue workers.</p><p>As UAVs shrink and grow, it will alter how we define them. Along with providing previously difficult-to-obtain images and delivering small payloads, UAVs will become a practical and labor-saving alternative to traditional means of transportation, cultivation, and commerce.</p></section><h3>Need UAV PCBAs Manufactured?</h3><p><a href="https://www.macrofab.com/pcba/" target="_blank" rel="noopener noreferrer">Check out MacroFab’s PCBA production services</a></p>

The Future of UAV Design: Very Big and Very Small

<h1 id="isPasted">Wired for Autonomy: Confronting PCBA Complexities in Mobile Robotics</h1><section><p>The field of untethered robotics is booming, and across industries, autonomous robots are rapidly assuming responsibility for an increasing number of tasks. In their expansion into increasingly diverse industries, these robots place additional demands on their internal workings, specifically the PCBAs that help them function.</p><p>However, developing PCBAs for autonomous robot systems presents several unique challenges that electrical engineers must overcome to succeed. We take a deep dive into these challenges by exploring design considerations beyond those associated with conventional PCBAs.</p><h3>Beyond the Basics: Design Considerations for Autonomous Robots</h3><p>While core electrical principles remain a top priority, autonomous robotics introduces additional complexity to PCBA design that electrical engineers must consider from day one. To function properly, these machines must anticipate and plan for the unexpected in harsh, changing conditions.</p><p>Intuitive Machines’ Odysseus moon lander recently brought this to light, when the private spacecraft <a href="https://www.reuters.com/technology/space/moon-lander-described-alive-well-day-after-white-knuckle-lunar-touchdown-2024-02-23/" target="_blank">landed on the moon’s surface</a>. As much as the sideways landing attracted media attention, few reports focused on last-minute troubleshooting that kept the mission afloat, a testament to the quick-thinking nature of the engineers involved.</p><p>Here are some of the important factors to consider when designing PCBAs for untethered robotics:</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713979758192-1713979758192.png" alt="Autonomous robot design considerations" class="fr-fic fr-dii"><ul><li><strong>PCBAs Must Prioritize Efficiency:</strong> Untethered robots almost entirely rely on batteries, so PCBAs must focus on efficiency. The key to this is meticulous component selection, such as using low-power microcontrollers and efficient voltage regulators, as well as excellent circuit design that minimizes standby currents. Using clock gating also maximizes battery life and reduces heat generation.</li><li><strong>Maintain Signal Integrity Amid Noise:</strong> Robots operate in dynamic environments with <a href="https://www.macrofab.com/blog/bypass-caps-decouple-your-way-to-cleaner-power/" target="_blank">potential electrical noise</a> from motors, sensors, and external sources. EMI can wreak havoc on robotic sensors, causing glitches, calibration issues, or even complete sensor failure. Consider layout strategies in detail to cut crosstalk and ground loops and maintain clear signal transmission.</li><li><strong>Build for Endurance:</strong> Many robots are subjected to extreme temperatures, temperature fluctuations, vibrations, and shocks. Use ruggedized PCBA boards that have components with adequate vibration and temperature ratings. To prevent overheating, soldering must be properly performed to handle thermal expansion and contraction, mechanical fatigue, and dust and moisture infiltration. Enclosures need to protect against dust and moisture egress.</li><li><strong>Size Matters:</strong> Robots must be mobile, so PCBAs must also be compact and lightweight to minimize robot weight. Choose wisely when choosing mechanisms within your robot, like vacuum track-based models or electromagnetic ones. They may increase the mass of your robot and reduce maneuverability. High-density interconnect (HDI) techniques and minimizing wasted space become crucial.</li><li><strong>Don’t Compromise Reliability:</strong> Autonomous robots, operating alone, demand ultra-reliable PCBAs to minimize failure. Filtering tackles this by reducing sensor noise for cleaner data, smoothing data for fewer errors, extracting key features for better navigation, and even lowering processing load for faster decision-making. Redundancy and fail-safe features further enhance reliability.</li><li><strong>Play by the Rules:</strong> Robots must comply with <a href="https://www.macrofab.com/blog/safeguarding-pcba-design-from-electromagnetic-interference/" target="_blank">Electromagnetic Compatibility (EMC) regulations</a> to ensure proper operation and avoid interfering with other electronic devices. Shielding techniques and filtering components become necessary.</li><li><strong>Ensure Maintainability:</strong> After assembling, it’s crucial to diagnose faults and perform maintenance. Make sure test points are conveniently accessible after the final assembly. Consider implementing Built-in Test (BIT) features on the PCBA for self-diagnostic features or options for wireless troubleshooting.</li></ul><h2><br></h2><h3>The Unexpected Factors: When Biology Interferes</h3><p>Biological influences are often overlooked when designing PCBAs for autonomous robotics but are an important factor. Autonomous robotics may work in many different environments, encountering biological challenges that can undermine even the most robust and reliable designs.</p><h3><p>Biofouling</p></h3><p>Biofouling, or the accumulation of microorganisms on surfaces, happens most frequently in aquatic environments. However, this issue can also occur within humid industrial settings or food processing facilities. Biofouling causes issues in many ways including:</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713979758511-1713979758511.png" alt="Biofouling" class="fr-fic fr-dii"><ul><li><strong>Reduced Performance:</strong> Fouling on sensors, thrusters, and hulls can decrease efficiency and accuracy. As a result, sensors become less sensitive, propellers drag more, and overall power consumption increases. Special coatings applied to surfaces can deter organism attachment.</li><li><strong>Problems with Navigation:</strong> Fouling on navigational equipment leads to positioning and localization errors, which make it difficult for the robot to map its surroundings, keep its trajectory, and reach its destination.</li><li><strong>Maintenance Issues:</strong> Regular cleaning to remove biofouling is essential, particularly in remote locations. As a result, downtime occurs and reduces operational efficiency. Prevent biofouling with brushes or wipers, as well as scheduled cleaning protocols.</li><li><strong>Damage and Disruption:</strong> Biofouling can cause physical damage by promoting barnacle growth and corroding structures. Choosing materials that discourage organism growth is a passive defense, and monitoring systems can detect biofouling early and trigger automatic cleaning.</li></ul><p>Especially within industrial and food processing industries, biofouling can create a surprising but challenging issue for logistics robotics in order fulfillment, for example, or other autonomous vehicles. Make sure to consider this possibility when designing for specific applications.</p><h3><br></h3><h3>Biological Challenges Across Environments</h3><p>While biofouling dominates aquatic environments, other biological factors impact robots in other settings:</p><ul><li><strong>On Land:</strong> Dust, dirt, and debris can accumulate on sensors and cameras in terrestrial robots, hindering performance. Agricultural robots may encounter challenges with mud and plant debris.</li><li><strong>Airborne:</strong> Airborne robots face issues with dust, pollen, insects, and other airborne particles that can increase drag, reduce lift, and affect sensor accuracy.</li></ul><p>To address animal-related challenges, EEs can employ design strategies like:</p><p><strong>1. Physical Resilence:&nbsp;</strong></p><ul><li><strong>Challenge:</strong> Animals may chew on cables or antennas, causing malfunctions.</li><li><strong>Solution:</strong> Employ ruggedized components, reinforced substrates, and protective enclosures to enhance PCBA durability against physical damage from animal interactions. Additionally, utilize encapsulation and conformal coatings to safeguard critical components from moisture, dust, and possible damage by animals.</li></ul><p><strong>2. Sensor Integrity</strong>:</p><ul><li><strong>Challenge</strong>: Animals brushing against sensors can distort sensor inputs, leading to navigation errors.</li><li><strong>Solution:</strong> Design sensors with robust shielding, noise filtering capabilities, and redundancy features to ensure reliable operation and accurate data despite potential interference from animals. Develop strategies for preventing animals from brushing against sensors to keep distortions and navigational errors from happening. For example, anti-fouling paints or cages around the robot could prevent fouling, or sensors might be placed where animals cannot access them.</li></ul><p><strong>3. Mobility Optimization</strong>:</p><ul><li><strong>Challenge:</strong> Animals blocking pathways or obstructing movement can impede the robot’s forward progress.</li><li><strong>Solution:</strong> Develop strategies to address mobility constraints caused by animals blocking pathways or obstructing movement, ensuring that robots can navigate effectively and complete their objectives. This could include low-power LEDs or subtle sounds that encourage animals to move away. Optimize power management systems to maximize operational autonomy and extend battery life in resource-constrained environments where robots may interact with animals.</li></ul><h3>Security: The Next Level in AMR PCBA Design</h3><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1713979758575-1713979758575.png" alt="AMR PCBA security" class="fr-fic fr-dii"><p>AMR PCBA security</p><p>PCB design traditionally focuses on protecting against electrical malfunctions and physical damage. However, for AMRs (autonomous mobile robots) connected to the internet, cybersecurity emerges as a key concern. Hacking hazards present significant security risks. A compromised robot can open the door to major security breaches. Thus, incorporating encryption and secure boot mechanisms in PCBA design is essential to block unauthorized access.</p><p>Hardware Trojan Horses also pose a silent yet profound threat. These sneaky modifications, made during manufacturing, can go almost unnoticed. To counteract this, it’s critical to partner with trustworthy suppliers and employ hardware authentication methods.</p><p>Consider working with a partner with a connected technology platform that keeps you in touch with your manufacturing process from start to finish. Moreover, work with a partner that employs robust security practices and can provide proof of such, such as ISO and ITAR certifications, or membership in the ERAI, an organization established to <a href="https://www.macrofab.com/blog/electronics-industry-counterfeit-parts-problem/" target="_blank">combat counterfeit electronics</a> and high-risk components in the electronics industry. MacroFab holds these standards, and it is a member of ERAI.</p><p>Another challenge is the theft of PCBAs after robot deployment, especially those containing valuable intellectual property. Consider using tamper-evident seals or protective enclosures if you will be installing robotics in an unsupervised area.</p><p><strong>Want to read more about designing PCBAs for robotics?

This technique ensures precise pipeline alignment and involves simultaneous excavation and pipe installation, enhancing safety and efficiency. Widely used for utilities, microtunneling's precision and reduced environmental impact make it a preferred choice for constructing water, sewage, and other infrastructure systems in congested settings.</p><p dir="ltr">This article highlights the progress a young engineering student team from Switzerland has made with its self-developed micro tunnel boring machine. It describes the project on its way to revolutionizing the tunneling industry with specific regard to its innovative 3D-printing-like tunneling mechanism.</p><h2 dir="ltr">The Journey of Swissloop Tunneling</h2><p dir="ltr"><a href="https://swisslooptunneling.ch/" target="_blank">Swissloop Tunneling</a> is a student group from ETH Zurich that focuses on developing innovative tunneling technologies. This team, composed of students, works on designing and testing tunnel boring machines that incorporate advanced technologies and methods. Their efforts aim to enhance the efficiency and reduce the costs of tunneling processes, contributing to the broader goal of revolutionizing tunneling to facilitate ambitious infrastructure projects, including proposed systems like the Hyperloop transportation system.</p><p dir="ltr"><em><strong>Further reading:&nbsp;</strong></em><a href="https://www.wevolver.com/article/swissloop-tunneling-revolutionizing-the-tunneling-industry" target="_blank"><strong><em>Swissloop Tunneling: Revolutionizing the Tunneling Industry</em></strong></a></p><p dir="ltr">Throughout the last 3 years, over 100 Swissloop Tunneling members have made contributions to a common goal: unleashing the potential of time-, cost-, and resource-efficient tunneling. In this regard, innovation is needed to accelerate the infrastructural progress to benefit society by supporting the rapid expansion of connected underground systems. Therefore, Swissloop Tunneling aims to contribute to advancements in technology, demonstrated by its two iterations of prototypical tunnel boring machines since its founding in 2020.&nbsp;</p><p dir="ltr">Building upon its first model named Groundhog Alpha, the team has maintained the first machine components’ strengths while further extending it with technological add-ons, designing certain subsystems from scratch, conducting tests, and optimizing for higher reliability. Those efforts have now led to the current model Groundhog Beta.</p><h2 dir="ltr">The Groundhog Beta</h2><p dir="ltr">The current model of the association’s (micro) tunnel boring machine named Groundhog Beta consists, among others, of these functions:</p><h2 dir="ltr">Erosion</h2><p dir="ltr">Extracts and processes the underground material during the boring phase. At the front of the machine, where the cutterhead is placed, a special soil-conditioning foam is used to help decompose the sticky clay ground in Bastrop (TX), where the prototype was being tested. The erosion subsystem can further handle small to medium-sized rocks by crushing them into smaller pieces. A suctioning mechanism then transports the eroded material through and out of the machine. At this point, an external sedimentation system is ensuring a constant circulation of used water and the removal of the extracted material.</p><p dir="ltr"><span class="fr-img-caption fr-fic fr-dib" style="width: 790px;"><grammarly-extension data-grammarly-shadow-root="true" style="position: absolute; top: 0px; left: 0px; pointer-events: none;" class="dnXmp"></grammarly-extension><grammarly-extension data-grammarly-shadow-root="true" style="position: absolute; top: 0px; left: 0px; pointer-events: none;" class="dnXmp"></grammarly-extension><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEzNzExOTM0NDY1LXguanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib" alt="groundhog-beta-soil-conditioning-foam"><span class="fr-inner" spellcheck="false">Fig. 1: Groundhog Beta tackling clay using soil conditioning foam</span></span></span></p><h2 dir="ltr">Navigation</h2><p dir="ltr">Consists of a two-component system. The steering component allows for angled digging and enables withholding stronger vibrations. It consists of a comprehensive sensory system to achieve an accurate autonomous movement of the machine.

The liner mechanism simultaneously builds the interior tunnel wall while continuously moving forward with the tunnel boring machine, acting like a 3D printer. As it stands right now, a mechanism of this type has not been tested in tunneling yet and provides an ecologically sustainable solution regarding the reusability of the wall material. By using a pneumatic system, a polypropylene granulate to later build the tunnel wall gets transported into the machine. It then gets extruded by melting it and steering the viscous material into the right shape, finally being cooled down to achieve its intended tunnel wall structure. This mechanism has been optimized since last year - especially in terms of reliability. Additionally, an external testing system was designed to make isolated testing of this subsystem’s functionality possible. In the end, a 15mm thick tunnel wall is produced, being able to withhold the intense forces of machine and earth pressure.</p><p dir="ltr"><span class="fr-img-caption fr-fic fr-dib" style="width: 790px;"><span class="fr-img-wrap"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzEzNzExOTc1MDE2LURTQzA2NDY1LmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 100%px;" class="fr-fic fr-dib" alt="groundhog-beta-tunnel-lining"><span class="fr-inner" spellcheck="false">Fig. 3: Polymer starting to come out of the tunnel lining component on the right</span></span></span></p><h2 dir="ltr">Achievements Over the Years</h2><p dir="ltr">In addition to refining the engineering processes, the Swissloop Tunneling team has consistently participated in every Not-a-Boring Competition an event aimed at fostering innovation in tunneling technologies.
