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.

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.

Dead Reckoning 101: Everything You Need to Know

<p id="isPasted">We did a quick check, just now, on the current wildfire situation in British Columbia.</p><p>Nine wildfires were burning and labelled as “Out of Control” by the BC Wildfire Service. An additional two fires were categorised as “Wildfires of Note.” And we’re still very early in the wildfire season.</p><p>Recent years have seen an increase in devastating wildfires – in British Columbia, Alberta, California, Hawaii and elsewhere in North America. A 2014 fire in the Northwest Territories completely destroyed 8.5 million acres (3.44M hectares). There have also been massive wildfires in Portugal, Australia (42 million acres/17M hectares burned in 2019/2020), Russia – and other countries as well.</p><p>These examples are indicative of a trend; there’s compelling (and troubling) data to back this up.</p><p>“Multiple studies have found that climate change has already led to an increase in wildfire season length, wildfire frequency, and burned area,” says the United States Environmental Protection Agency. “The wildfire season has lengthened in many areas due to factors including warmer springs, longer summer dry seasons, and drier soils and vegetation.”</p><p>What’s worse is that major wildfires actually contribute to the likelihood there will be more of them in the future.</p><p>“Climate change is one of the major drivers of increasing fire activity,” says the <a href="https://www.wri.org/insights/global-trends-forest-fires" target="_blank">World Resources Institute</a>, which states that “the <a href="https://www.globalforestwatch.org/map/?map=eyJkYXRhc2V0cyI6W3siZGF0YXNldCI6InRyZWUtY292ZXItbG9zcy1maXJlcyIsIm9wYWNpdHkiOjEsInZpc2liaWxpdHkiOnRydWUsImxheWVycyI6WyJ0cmVlLWNvdmVyLWxvc3MtZmlyZXMiXX0seyJkYXRhc2V0IjoicG9saXRpY2FsLWJvdW5kYXJpZXMiLCJsYXllcnMiOlsiZGlzcHV0ZWQtcG9saXRpY2FsLWJvdW5kYXJpZXMiLCJwb2xpdGljYWwtYm91bmRhcmllcyJdLCJvcGFjaXR5IjoxLCJ2aXNpYmlsaXR5Ijp0cnVlfSx7ImRhdGFzZXQiOiJ0cmVlLWNvdmVyIiwibGF5ZXJzIjpbInRyZWUtY292ZXItMjAxMCJdLCJvcGFjaXR5IjoxLCJ2aXNpYmlsaXR5Ijp0cnVlfV19" target="_blank" rel="noopener">latest data</a> on forest fires confirms what we’ve long feared: Forest fires are becoming more widespread, burning nearly twice as much tree cover today as they did 20 years ago…</p><p>“Extreme heat waves are already <a href="https://www.npr.org/2021/11/08/1052198840/1-5-degrees-warming-climate-change" target="_blank" rel="noopener">5 times more likely</a> today than they were 150 years ago and are expected to become even more frequent as the planet continues to warm. Hotter temperatures <a href="https://yaleclimateconnections.org/2021/08/climate-change-and-droughts-whats-the-connection/" target="_blank" rel="noopener">dry out the landscape</a> and help create the <a href="https://www.edf.org/climate/heres-how-climate-change-affects-wildfires" target="_blank" rel="noopener">perfect environment</a> for larger, more frequent forest fires. This in turn leads to higher emissions from forest fires, further exacerbating climate change and contributing to more fires as part of a “<a href="https://www.wri.org/insights/6-graphics-explain-climate-feedback-loop-fueling-us-fires" target="_blank">fire-climate feedback loop</a>.”</p><p>This is, obviously, concerning. Existing firefighting and fire suppression techniques haven’t changed much over the years – and the threat is growing.</p><p>A new Canadian company, SkyScout AI, believes it holds part of the solution. And after seeing a demonstration of some of its capabilities recently in British Columbia, we’re inclined to agree.</p><p><em>Below: SkyScout Ai’s Shawn Bethel prepares a “drone tanker” at a demonstration outside Penticton. Scott Simmie photo</em><em><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE5NTk5NzQxMTE1LURTQ0Y3Mzg3LXNjYWxlZC5qcGcud2VicCIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 100%px;" class="fr-fic fr-dib" alt="Drone Tank Prep"></em><br></p><h3 id="isPasted">Sky Scout AI</h3><p>So. What is SkyScout Ai – and what does its solution entail?</p><p>It starts with the leadership.</p><p>“It’s a company that’s comprised of people who want to make a difference for their communities and trying to save them as climate change drives increase in fire activity,” says Chief Operations Officer and Co-Founder Geoff Griffiths.</p><p>We’ll explore some of that shortly. First, though, we asked Griffiths for his elevator pitch.</p><p>“We’ve come up with a first-in-class vertically integrated solution&nbsp;that spans satellite and drone early detection. And we have the capability with our drone tanker to not only fight the fire but protect the communities from fire by pre-treating vegetation and housing with our EPA-certified fire inhibitor called Citrotech. So it really is about a fully vertically integrated approach that really focuses on interface fires – those fires that interface with communities and critical infrastructure, that’s really our niche.”</p><p>All you have to do is think back to Kelowna last year and the threat posed to the city by wildfires. The <a href="https://en.wikipedia.org/wiki/McDougall_Creek_fire#:~:text=The%20McDougall%20Creek%20Fire%20was,at%205%3A59%20pm%20PDT." target="_blank">McDougall Creek Fire</a> forced the evacuation of West Kelowna and made headlines across the country. Griffiths has seen such fires hit close to home.</p><p>“My parents were living in Kelowna during a major wildfire in 2003. Their neighbourhood burned down so it’s always been in the back of my mind – wanting to do something.”</p><p><em>Below: Helping detect and proactively inhibit wildfires also protects wildlife. Scott Simmie photo</em><em><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE5NTk5Nzc3OTcwLURTQ0Y3MjY3LXNjYWxlZC5qcGcud2VicCIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width: 100%px;" class="fr-fic fr-dib" alt="Wildlife"></em><br></p><h3 id="isPasted">How It Works</h3><p>The SkyScout Ai system integrates multiple components that collectively can – as the company states – “Detect, respond, protect.” And there’s a lot of technology at play to make that happen.</p><p>Though the startup is at the demonstration stage, here’s how the fully integrated system will work.</p><p>Let’s take the city of Kelowna as an example. In a long-term, proactive scenario, SkyScout Ai would place multiple permanent drone docks at several locations around the city. Those weather-resistant docks would contain drones with high-resolution thermal sensors. They’re simply sitting, with the drones fully charged, waiting for a signal.</p><p>That signal could come, automatically, from satellite data. Satellites are capable of detecting thermal hotspots and lightning strikes. So, in this example, let’s say a lightning strike is detected near Kelowna. That data and GPS location is instantly relayed, via SkyScout Ai’s software, to one or more of the thermal drones. The docks open and the drones launch, headed to the area of interest.</p><p>If the drones pick up a thermal signature – a fire – that information can, in turn, be relayed immediately to First Responders. So a fire crew might be quickly dispatched. Because this early warning system can detect so quickly, that crew will have a much better chance of extinguishing a fledgling fire.</p><p>But, as we all know, fires can spread tremendously fast. And that’s where SkyScout Ai has some other options to help protect valuable assets. Those options include what the company calls “tanker drones” and a very unique product called Citrotech. It’s a food-grade fire inhibitor that can prevent ignition (and which we’ve seen in action).</p><p>If it’s still a small fire, a tanker drone carrying Citrotech could be dispatched to extinguish the fire by aerosolising that compound over the site. But don’t start thinking this has the power of a water bomber – it doesn’t (though the company envisions larger drone tankers in its future).</p><p>Rather, a drone carrying Citrotech on board has the capability to protect infrastructure at that wildfire-urban interface point. The tanker can quickly spray the roofs of multiple homes or other structures requiring protecting. The product dries quickly and crystallises. Once applied, it is nearly impossible for that protected surface to ignite – even if that roof gets coated with burning embers (a common way houses are ignited during wildfires). Citrotech could also be sprayed on dry vegetation near those structures, effectively creating a firebreak.</p><p>“Citrotech modifies the material its on at a molecular level and has extremely high efficacy when it’s dry,” explains Chief Commercial Officer and Co-Founder Shawn Bethel. “So it coats combustible vegetation and really just inhibits the ability of combustible vegetation to combust. You can’t get it to ignite.”</p><p>Bethel knows what he’s talking about when it comes to wildfires. He’s the former BC Provincial Fire Control Officer – who was responsible for all of BC’s firefighting resources out of the Provincial Wildfire Operations Centre. His <a href="https://www.skyscoutai.com/team" target="_blank">bio on the SkyScout Ai website</a> says “He brings 25+ years of operational wildland fire management experience including senior roles on incident command teams and aerial firefighting asset management. Shawn also brings an additional 15+ years working in the private sector spearheading global business operations with technology services companies providing wildfire mitigation solutions and fire aviation services.”</p><p>So Bethel obviously has deep expertise in wildfires, including all available suppression technologies.</p><p>“SkyScout Ai is pushing to protect the wildland-urban interface from new fires starting from ember transfers and lightning strikes,” he says. “When it’s applied in advance of anticipated new wildfire activity, it has time to dry – which is easy to do during drought wildfire weather conditions – and essentially stops fire in its tracks.”</p><p>Again – this is not a solution to extinguish a massive raging fire. But it definitely is capable of stopping small fires from becoming larger, and protecting homes, vineyards, orchards and critical infrastructure from igniting.</p><p>“This is not for Rank 6 conflagration fires. What this is for inception fires, combustible vegetation near homes, near assets, and for infrastructure and roadways. Citrotech is an excellent fire inhibiting product.”</p><p><em>Below: Shawn Bethel, followed by a DJI Agras T-40 during a SkyScout Ai demonstration.

That command centre (the first of many planned) contained a dock for a thermal drone, a massive spraying drone (in this case, a DJI Agras T-40), Citrotech and a control centre for the pilot(s) who will monitor autonomous operations and manually fly the tanker drone when necessary. That Command Centre, btw, is towed on a trailer. But it has been designed to quickly detach and the entire operation can be lifted by helicopter to any location where it’s required.</p><p>SkyScout Ai came to test its technology in advance of forthcoming demonstrations for the media, First Responders and other decision makers.</p><p>During testing, a small fire was set using a small fire starter brick placed on a stone. A thermal drone with RTK positioning was dispatched to locate the hotspot. In a full demo, that data and GPS location would be &nbsp;automatically forwarded to First Responders or a tanker drone which would head to that spot to dispense Citrotech (which can not only inhibit, but also extinguish).</p><p>That was impressive. But there were two real show-stoppers.</p><p>In the first, a pile of dry tumbleweeds were treated with Citrotech by spraying a fine mist on them (this was done manually, but could easily be done by the tanker drone). Thirty minutes later, a pile of untreated tumbleweeds was placed directly adjacent to the treated section. Then Bethel ignited the untreated pile with a blow torch. Within seconds, flames were shooting about two metres in the air. The burn was rapidly spreading.</p><p>And when it hit the treated tumbleweed? It stopped dead. Nothing burned.</p><h3>&nbsp;</h3><h3>Drone Tanker</h3><p>In the second exercise, the drone tanker was filled with water. Two piles of tumbleweeds (one treated, one untreated) were again placed in a pile. The tumbleweeds were ignited and the Agras took off. From a distance of about four metres AGL, the spraying function was engaged. The blaze was extinguished in mere seconds.</p><p>So with near real-time detection using satellites and thermal drones, a tanker (or other First Responder, depending on the threat) could be dispatched literally within minutes of a lightning strike. And if that fire appeared to be growing and potentially threatening homes, vineyards, or other important infrastructure, the tanker could quickly coat these with Citrotech. Because it’s EPA-approved and food-safe, there’s no issue with spraying crops like grapes, cherries, etc. You could literally drink a glass of this stuff and be fine (though we didn’t try that).</p><p><em>Below: Shawn Bethel prepares to manually treat some dry brush with Citrotech</em><em><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1719599925770-DSCF7437-scaled.jpg.webp" style="width: 100%px;" class="fr-fic fr-dib"></em></p><h3 id="isPasted">Business Model</h3><p>Though the Citrotech is important, a key part of the value proposition is in the early detection and location of fires. The earlier a fire is detected, the better the odds of mitigation before it can get out of control.</p><p>Here, SkyScout Ai has the advantage of integrating that satellite data directly into its software – which can then trigger an immediate launch of one or multiple thermal drones. With RTK positioning, they can get a precise bead on the trouble spot – and send back not only thermal images but also high resolution photos/imagery that can be shared with First Responders. Depending on the size of the conflagration and location, a tanker drone can also be dispatched.</p><p>So the primary business model would be to have a contracts with cities adjacent to forests. The docks with thermal drones would be installed at strategic locations as the first line of defense, with a tanker drone on standby. There’s also the option, as mentioned, to lift the entire command centre by helicopter to a location where it’s urgently needed.</p><p>&nbsp;</p><h3>Citrotech</h3><p>The fire inhibitor, of course, could be dispensed by drone in the above scenario. But SkyScout Ai has an exclusive distribution contract for Citrotech’s product (known as Mighty Fire Breaker MFB-31) for all of Canada. It has plans to sell the product to individuals or companies that would like to have it handy for the ability to treat their buildings or property in advance of a threat. (Citrotech washes off in the rain, but there’s generally not much rain happening during the drought-like conditions that generally precede major wildfires. When sprayed prior to painting or staining, it remains effective.) So this product is definitely part of the equation.</p><p>“The secret sauce also is the addition of citrotech,” says Geoff Griffiths. “That fire inhibitor is the only fire inhibitor certified by the EPA in the US. It’s a non-toxic option that hasn’t existed before, and as you can see by our demonstration is highly effective.”</p><p>Griffiths says the timing for the SkyScout Ai solution is perfect.</p><p>“Obviously climate change is driving a lot of the wildfire activity that we’re seeing across the world. And regulators, government, private industry now realize that the standard ways they’ve approached wildfires in the past aren’t working or maybe aren’t good enough anymore. They’re open to new approaches.&nbsp;Add in the drone technology, satellite detection, and it’s a critical extra step in the evolution of a solution.”</p><p><em>Below: SkyScout Ai’s first Mobile Command Centre.

In Kelowna last year, we were called upon to help detect hotspots indicating subterranean combustion at a landfill. Locating and extinguishing hotspots like these (or burning tree roots – which can burn for weeks and reignite new fires), are also a critical part of wildfire suppression.</p><p>When SkyScout Ai was being formed, InDro Robotics was involved.</p><p>“We’re assisting with technology on the drone side of things,” says InDro Robotics CEO Philip Reece.</p><p>“We’re providing pilots and other technical support. For example, we’re putting our InDro Command module onto the drones. This enables not only Command and Control via 5G and dense data throughput, but also the integration of all of the drone data into the SkyScout Ai dashboard. As the company grows and Transport Canada regulations change, we anticipate assisting with the R&amp;D required for much larger tanker drones…</p><p>“Wildfires can be devastating and the models unfortunately predict will only get worse.

Transforming Robotics with Next-Gen Integrated Motion Devices - A Synapticon and Nexperia Case Study

<p dir="ltr" id="isPasted">Industrial robots have brought programmable automation to factory floors and areas for storage, sorting, and packing, as businesses seek to increase their productivity and reduce operating overheads.</p><p dir="ltr">More recently, collaborative robots (cobots) have arrived and created an extra, new world of application opportunities. Designed to work safely alongside humans, they bring the unique ability to act as co-workers contributing to the processes that must be completed to achieve the result.</p><p dir="ltr">This softer image of the robot as a coworker – in contrast to those unapproachable, caged superhumans used for hazardous jobs like heavy lifting, welding, and paint spraying - promotes the adoption of cobots in a wider range of tasks. It raises the exciting prospect of combining human qualities such as natural dexterity and visual acuity, combined with the superior speed, repeatability, and strength of the robot.&nbsp;</p><p dir="ltr">Cobots are also assumed to have a reliability advantage over humans, with no tendencies towards illness, lateness, or loss of concentration while working. As important as performance, efficiency, and safety, reliability needs to be designed in to ensure that the cobot will deliver the operator’s expected return on investment (ROI).</p><h2 dir="ltr">Motor-Drive Design Requirements</h2><p dir="ltr"><span class="fr-img-caption fr-fic fr-dii" style="width: 780px;"><span class="fr-img-wrap"><img alt="A diagram of a diagram Description automatically generated" src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE3OTg1NjYwOTk2LTE3MTc5ODU2NjA5OTYucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" width="602" height="242" class="fr-fic fr-dii" style="width: 780px;"><span class="fr-inner">Figure 1. Cobot power, communication, sensing, and driving subsystems.</span></span></span></p><p dir="ltr" id="isPasted">Figure 1 describes the underlying electrical architecture of a typical industrial cobot. The motors and motor-drive circuits that move each of the cobot’s joints must be able to handle the necessary loads and movements without straining or overheating. Motors that offer a high torque-to-weight ratio and small form factor in relation to the demands at each joint are usually preferred to permit a lightweight and compact robot design that can be safe and easy to work with around humans.&nbsp;</p><p dir="ltr">However, such requirements put a significant level of expectations on the motor-drive circuitry where the power electronics reside. The smallest possible module size is required, consistent with the goals of compactness and light weight. The size constraints limit thermal performance, which increases the stress on power semiconductor components. Frequent starting and stopping, as well as emergency stops when safety sensors indicate proximity of a human coworker, generate heat within the power semiconductors which must be dissipated to preserve the device.&nbsp;</p><p dir="ltr">Cobot applications typically operate with a bus voltage of below 60V, translating to the power stage for the motor driver being driven by MOSFETs in a three-phase inverter topology. High energy efficiency is clearly an important consideration in current markets, so MOSFETs with low on-resistance are desirable. On the other hand, high availability and uptime are critical requirements that directly impact productivity and ROI, placing emphasis on choosing devices that are designed for ruggedness and reliability.&nbsp;</p><p dir="ltr">When driving high-power motors, MOSFETs are vulnerable to failures caused by locked rotors, parasitic effects and brownout events that can expose the devices to excessive current and prolonged switching time. To withstand these threats, the chosen device needs a strong safe operating area (SOA) and avalanche robustness. Enhancing these parameters usually comes at the expense of increased RDS(on). Hence trading-off some efficiency in pursuit of superior thermal dissipation and higher excess-voltage, current-surge, and avalanche capabilities is warranted. Seeking all these qualities together with a compact footprint to minimise the size of the driver module narrows the selection of suitable devices.</p><p dir="ltr">In fact, the constraints that determine the choices of power semiconductors for cobots are remarkably close to those for today’s heavy-duty cordless handheld power tools, such as high-power drills, impact wrenches, sanders, and grinders. These, too, must respect tight limitations on physical dimensions, while also delivering high current and withstanding intensive thermal loads particularly during repeated starting and stopping. German sports equipment pioneer Jaykay GmbH encountered similar limitations when creating its range of innovative e-trucks and paddle boards, and overcame them using Nexperia MOSFETs that are optimised for ruggedness and reliability in compact motor drives.</p><h2 dir="ltr">Power Semiconductor Selection</h2><p dir="ltr">Given the complexity of today’s application demands and the latest advances in device technology, focusing on the traditional RDS(on) x Qg figure of merit (FOM) is no longer the best starting point when selecting MOSFETs. The differentiating factor for every design is to find the best silicon-package combination.</p><p dir="ltr" id="isPasted">While optimisation and enhancement at the silicon level has blazed the trail for new MOSFETs with greater current and voltage handling capability than previous generations, the package technology plays a massive role in meeting the needs of high-power applications. Compared to traditional power packages, Nexperia’s LFPAK technology combines significantly lower parasitic inductance and electrical resistance with greatly improved thermal performance. The key innovation, enabling these improvements, is the copper clip bond that replaces conventional bond wires at the source connection, as shown in Figure 2. Compared to wire bonds, the copper clip bond prevents localised current crowding thereby eliminating hotspots and ensuring a more uniform current spread, while also acting as a heat sink to the die.&nbsp;</p><p dir="ltr"><span class="fr-img-caption fr-fic fr-dii" style="width: 780px;"><span class="fr-img-wrap"><img alt="Full screen preview" src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzE3OTg1NzgzMzM4LTE3MTc5ODU3ODMzMzgucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" width="485" height="450" class="fr-fic fr-dii" style="width: 780px;"><span class="fr-inner">Figure 2: Transparent view of a LFPAK56 package(LFPAK package image)</span></span></span></p><p dir="ltr" id="isPasted">Combining the latest silicon and LFPAK56 package has enabled a half-bridge MOSFET pair comprising high-side and low-side devices for 3-phase motor control in a 5mm x 6mm outline. The package uses flexible leads to improve overall reliability and the internal copper clip that connects the silicon drain and source terminals to the package leads has greater electrical performance and thermal dissipation than traditional bond wires, thereby boosting reliability. While the MOSFET drain tab remains the dominant path in dissipating heat from the die, the LFPAK source clip makes a significant contribution. Therefore, ensuring a suitable amount of copper in the PCB connections to the source pins helps to maximise the overall thermal performance.</p><p dir="ltr">In high-power applications, where space constraints conflict with demands for high performance and robustness, copper clip package technology is an extremely valuable part of the solution that helps to maximise the value of the silicon. Robustness and reliability also comes down to thermal cycling and in some cases, the sheer level of current the devices need to handle in case of a fault condition.&nbsp;</p><h2 dir="ltr">Conclusion</h2><p dir="ltr">For robot makers, delivering a safe and cost-effective system to the marketplace calls for intelligent design decisions at all stages, including an accurate, flexible, and responsive control strategy, cost-effective and optimally sized motor, and reliable and efficient power semiconductors. &nbsp;Given the intended growth of this market, with the ever-increasing power density, the power semiconductors are a critical component to ensure that the motor and, by extension, the entire cobot is driven efficiently, reliably, and safely.&nbsp;</p>
