Without the right connectivity, at the best quality and price for your specific requirements, any IoT project is unlikely to ever get beyond the initial planning stages.</p><h2><strong>5 key IoT connectivity considerations:</strong></h2><h3><strong>1. The location, power, and bandwidth payoff</strong></h3><p>If you haven&rsquo;t realized it already, you will soon. IoT projects are all about negotiating requirements and payoffs to find the right balance for your service. Your use case will determine in which location you need your connectivity to function, how long you need your devices&rsquo; power supply to last, and whether you need low latency real-time updates, or less frequent, less speedy updates. Combined, this offers a roadmap when making a decision on the type of connectivity you will need.</p><h3><strong>2. Ease of network deployment</strong></h3><p>Successful IoT solutions must &nbsp;be integrated with existing technologies and infrastructure rather than attempting to build something entirely new from scratch. There is no value to either the end-user or the business in creating something that is more complex, more expensive and will take longer to deploy. And no one benefits if your IoT applications and devices are operating in a vacuum, &ldquo;talking&rdquo; only to each other. The challenge is how to streamline the deployment of devices, and the process for the transfer of data and connectivity to the rest of your operations. Plug-and-play IoT connectivity offers a simple way to do this, reducing both the cost and complexity of any IoT deployment. Legacy OT and IT systems need to be looped in, and your connectivity choice must take this into account.&nbsp;<strong>&nbsp;</strong></p></div></div></section><section data-element_type="section" data-id="b0402c5" data-particle-mobile-disabled="false" data-particle_enable="false"><div data-element_type="column" data-id="5b3122fa"><div data-element_type="widget" data-id="41ecac30" data-widget_type="image.default"><img data-fr-image-pasted="true" width="800" height="356" src="https://monogoto.io/wp-content/uploads/2022/11/monogoto-5-IoT-consedrations-for-IoT-projects-scaled-1-1024x456.jpg" alt="" srcset="https://monogoto.io/wp-content/uploads/2022/11/monogoto-5-IoT-consedrations-for-IoT-projects-scaled-1-1024x456.jpg 1024w, https://monogoto.io/wp-content/uploads/2022/11/monogoto-5-IoT-consedrations-for-IoT-projects-scaled-1-300x134.jpg 300w, https://monogoto.io/wp-content/uploads/2022/11/monogoto-5-IoT-consedrations-for-IoT-projects-scaled-1-768x342.jpg 768w, https://monogoto.io/wp-content/uploads/2022/11/monogoto-5-IoT-consedrations-for-IoT-projects-scaled-1-1536x684.jpg 1536w, https://monogoto.io/wp-content/uploads/2022/11/monogoto-5-IoT-consedrations-for-IoT-projects-scaled-1-2048x912.jpg 2048w" sizes="(max-width: 800px) 100vw, 800px" class="fr-fic fr-dii"></div><div data-element_type="widget" data-id="54e36838" data-widget_type="text-editor.default"><h3><strong>3. An IoT solution with scale and breadth</strong></h3><p>An IoT solution is unlikely to be static. Over time, you may add devices, design new applications or take advantage of technology upgrades. Your choice of connectivity needs to be able to scale to adjust to the changing scope of your projects.&nbsp;</p><p>This may seem difficult because every IoT service has slightly different requirements, but there is likely to be enough commonality between them to deploy a single connectivity service. To work, two things need to be in place. First, your chosen connectivity service has to scale effortlessly so that newly added endpoints don&rsquo;t affect overall service levels. Second, your connectivity platform should be built for the broad needs of the IoT industry so that it caters for a variety of applications, sensors, modules, and controllers, as well as varied protocols, networks, and connectivity types.</p><h3><strong>4. No fuss global coverage</strong></h3><p>Anyone who has traveled with a mobile phone knows that getting genuinely global data roaming can be hard. For IoT to be truly global, any attempt to DIY global, or even regional or national cellular coverage will add complexity and create additional opportunities for connectivity drops. Instead, bypass setting up, managing and troubleshooting a host of mobile network operator (MNO) relationships by connecting to a single connectivity platform that has already taken care of all this. &nbsp;You get quality of service, faster response times, and integrated connectivity in each location. And don&rsquo;t forget to look for a user-friendly management platform that offers full visibility of all your IoT applications, wherever they are in the world.</p><h3><strong>5. Upholding security and data privacy</strong></h3><p>The wireless portion of an IoT network can be a significant security risk. It needs to be adequately secured and, if managed by others (e.g. MNO), you need complete transparency and visibility to understand to/from where your IoT device is transmitting/receiving data. Without this, you are vulnerable to attacks or data leaks and are offering malicious actors a convenient entry point into your wider enterprise network.</p><p>With comprehensive self service functionality you are able to see what is happening, track data, block irrelevant IPs and allow only trusted IPs, and create a VPN to ensure a secure data transfer tunnel between your devices and your cloud platform.&nbsp;</p><p>Planning and future proofing will ultimately ensure the success of your next IoT project and connectivity is at the center of this. Find the right IoT connectivity partner and you&rsquo;ll be on your way to a long-term, scalable and successful project.</p></div></div></section>

As IoT evolves, projects are shifting from being experimental and exploratory to business critical. This makes them more complex, ensures they receive more scrutiny and, inevitably, increases the opportunities for things to go wrong. This is even more true when you consider that IoT devices and solutions have a long shelf life, making long-term success only possible if you’re properly planning and building today for the unknown factors in the future.

For every geometric axis that a joint can rotate around or extend along, this is counted as a Single Degree of Freedom.&nbsp;</p><p>In theory, there are quite a few types of joints that provide varying numbers of degrees of freedom in terms of rotation and translation (see the chart below). In practice, however, most robotic arms will be made up of a series of joints that provide one degree of freedom. The two most common joints are:</p><p><strong>Revolute Joint:</strong> Providing one degree of rotational freedom</p><p><strong>Prismatic Joint:&nbsp;</strong>Providing one degree of linear freedom</p><p>As such, robotic arms are often described in terms of how many total DoF they have. E.g. <a href="https://blueprintlab.com/products/manipulators/reach-bravo/" target="_blank">the Bravo 7</a> is a 6 Degree of Freedom robotic arm (Why not call it the Bravo 6?

Of course, there are a <a href="https://www.nist.gov/blogs/manufacturing-innovation-blog/4-types-robots-every-manufacturer-should-know" rel="noreferrer noopener" target="_blank">variety of different types of robotic arms</a> across different industries, ranging from one degree of freedom (sometimes called an &lsquo;axis&rsquo;) to over seven.</p><p><span class="fr-img-caption fr-fic fr-dib" style="width: 768px;"><span class="fr-img-wrap"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1649929821040-kinematic-pairs.png" style="width: 766px;" class="fr-fic fr-dib"><span class="fr-inner"><em id="isPasted">Chart Credit: Cavacece, Massimo &amp; Vita, L..

In other words, it does not move the position or orientation of the end-effector/gripper/tool/sensor (the part of the robot that &lsquo;does stuff&rsquo;). For <a href="https://blueprintlab.com/products/manipulators/" target="_blank">Blueprint Lab manipulators</a>, we usually have a set of jaws at the end of the robotic arm. To open or close the jaws of the robotic arm, we use a prismatic actuator (a fancy word for a motor and gear set &ndash; a single joint).&nbsp;</p><p>We define the reference point as a floating location in between the jaws of the manipulator. As the manipulator moves, it is this location that is being updated in terms of the &lsquo;position&rsquo; of the end-effector. If you want to grab something at position (x,y,z) with orientation (a,b,c), it is this position that is optimised in the<a href="https://robotacademy.net.au/masterclass/inverse-kinematics-and-robot-motion/" rel="noreferrer noopener" target="_blank">&nbsp;inverse kinematics algorithm</a>.</p><p>Because of this, the movement of the linear actuator to open and close the manipulator&rsquo;s gripper does not change the reference point and thus it is not providing a &lsquo;degree-of-freedom.&nbsp;</p><p>In this scenario, the prismatic actuator is providing a &lsquo;function&rsquo; but not a &lsquo;degree of freedom&rsquo;. As such, we may define a manipulator as having a different number of DoF and Functions; for example, the Bravo 7 is a 7-Function, 6 DoF manipulator, with one function being the open/close of the jaws.&nbsp;</p><p>Why is all this important?

RE2 Robotics Marks its 20th Anniversary with Launch of a New Robotic Arm

<p><strong>SITUATION&nbsp;</strong><br>Numerous industries rely on commercial divers to conduct underwater maintenance and repair tasks, including the maintenance and inspection of offshore oil rigs and pipelines, and the construction and repair of bridges, piers, and dams. With two-thirds of the earth’s surface covered in water, the commercial diving industry is a high-demand profession—and it is also one of the most hazardous for workers. Therefore, there is great potential for robotic systems to enhance worker productivity and safety, and to assist in the exploration of oceans and waterways.</p><p><strong>PROBLEM</strong><br>The U.S. Occupational Safety and Health Administration (OSHA) classifies commercial diving as a high-risk occupation, reporting that the industry has a “very high rate” of fatality and injury. Commercial divers often need to use machinery, tools, or materials that can expose them to hazards such as electrocution, burns, explosions, respiratory distress, or drowning. These risks are exacerbated by the need to work for extended periods of time in water with low visibility, constrained environments, or frigid temperatures. In addition, the extended exploration or inspection of marine objects is limited to the amount of time that divers can safely remain underwater, including the time it takes for divers to descend and resurface to rest and replenish their air tanks. Due to the strenuous nature of the work, commercial diving also has a high turnover rate— skilled divers typically don’t work past the age of 45, requiring younger, less experienced divers to be trained on a regular basis.</p><p><strong>SOLUTION</strong><br>Originally engineered for the U.S. Navy to operate in harsh marine environments, RE2 has developed a dual-arm, highly dexterous, electronically driven manipulation system designed for deep ocean use. <a href="https://www.resquared.com/underwater" rel="noopener noreferrer" target="_blank">RE2 Sapien Sea Class™</a> dual-arm system featuring two 6-degree-of-freedom arms that easily integrate with numerous remotely operated vehicles (ROVs) and are used in a variety of industry applications. RE2’s electric, energy-saving system frees up subsea vehicle power to allow cameras and sensors to interrogate the environment for extended periods of time. In addition, the system’s lightweight, compact design allows for a smaller footprint in constricted environments, allowing it to dexterously operate in precarious areas that are difficult, if not impossible for more traditional underwater systems to access. The RE2 Sapien Sea Class provides near human performance at human scale.</p><p></p><div class="fr-img-space-wrap"><span class="fr-img-caption fr-fic fr-dib" style="width: 300px;"><span class="fr-img-wrap"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1622222899209-Copy+of+ExploringNewDepths-FB+%281%29.png" style="width: 300px;" class="fr-fic fr-dib"><span class="fr-inner">RE2 Sapien(TM) Sea Class can reach depths of more than 300 meters.</span></span></span><p class="fr-img-space-wrap2">The system’s neutral buoyancy ensures that it stays controllable when performing a variety of inspection and repair tasks, even at depth. When both arms are used, the second arm provides stability in less-than-ideal conditions, such as in fast-moving currents; the system’s high degree of dexterity allows one arm to be used to perform a task while the other arm is used to secure the system to an object. To allow for extended subsea interactions, the closed, sealed design of RE2 Sapien Sea Class™ also features a multi-level corrosion management system, which includes the use of sacrificial anodes and anodized joints, providing a very rugged and reliable solution with minimal maintenance. Using a robotic system for underwater inspection and maintenance tasks can also allow older, skilled divers to stay on the job longer, as they may be able to transition to a topside role and use their experience to guide operations, whether through teleoperation or autonomously via RE2’s computer-vision and machine-learning algorithms, <a href="https://www.resquared.com/products" rel="noopener noreferrer" target="_blank">RE2 Detect™</a> and <a href="https://www.resquared.com/products" rel="noopener noreferrer" target="_blank">RE2 Intellect™</a>.&nbsp;</p></div><p></p><hr><p>How can RE2 Robotics help your team improve worker safety through robotics?
