This is staging - but I edited this directly from the DB - woo wooPowered by <a href="https://www.froala.com/wysiwyg-editor?pb=1" title="Froala Editor">Froala Editor</a>

This is staging

In the classic cartoon “The Jetsons,” Rosie the robotic maid seamlessly switches from vacuuming the house to cooking dinner to taking out the trash. But in real life, training a general-purpose robot remains a major challenge.Typically, engineers collect data that are specific to a certain robot and task, which they use to train the robot in a controlled environment. However, gathering these data is costly and time-consuming, and the robot will likely struggle to adapt to environments or tasks it hasn’t seen before.To train better general-purpose robots, MIT researchers developed a versatile technique that combines a huge amount of heterogeneous&nbsp;data from many of sources into one system that can teach any robot a wide range of tasks.Their method involves aligning data from varied domains, like simulations and real robots, and multiple modalities, including vision sensors and robotic arm position encoders, into a shared “language” that a generative AI model can process.By combining such an enormous amount of data, this approach can be used to train a robot to perform a variety of tasks without the need to start training it from scratch each time.This method could be faster and less expensive than traditional techniques because it requires far fewer task-specific data. In addition, it outperformed training from scratch by more than 20 percent in simulation and real-world experiments.“In robotics, people often claim that we don’t have enough training data. But in my view, another big problem is that the data come from so many different domains, modalities, and robot hardware. Our work shows how you’d be able to train a robot with all of them put together,” says Lirui Wang, an electrical engineering and computer science (EECS) graduate student and lead author of a <a href="https://arxiv.org/pdf/2409.20537" target="_blank">paper on this technique</a>.Wang’s co-authors include fellow EECS graduate student Jialiang Zhao; Xinlei Chen, a research scientist at Meta; and senior author Kaiming He, an associate professor in EECS and a member of the Computer Science and Artificial Intelligence Laboratory (CSAIL). The research will be presented&nbsp;at the Conference on Neural Information Processing Systems.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730247515325-MIT-HeteroGenRobot-02-press.jpg" style="width: 100%px;" class="fr-fic fr-dib">A figure shows how the new technique aligns data from varied domains, like simulation and real robots, and multiple modalities, including vision sensors and robotic arm position encoders, into a shared “language” that a generative AI model can process. Image: Courtesy of the researchers<h2>Inspired by LLMs</h2>A robotic “policy” takes in sensor observations, like camera images or proprioceptive measurements that track the speed and position a robotic arm, and then tells a robot how and where to move.Policies are typically trained using imitation learning, meaning a human demonstrates actions or teleoperates a robot to generate data, which are fed into an AI model that learns the policy. Because this method uses a small amount of task-specific data, robots often fail when their environment or task changes.To develop a better approach, Wang and his collaborators drew inspiration from large language models like GPT-4.These models are pretrained using an enormous amount of diverse language data and then fine-tuned by feeding them a small amount of task-specific data. Pretraining on so much data helps the models adapt to perform well on a variety of tasks.“In the language domain, the data are all just sentences. In robotics, given all the heterogeneity in the data, if you want to pretrain in a similar manner, we need a different architecture,” he says.Robotic data take many forms, from camera images to language instructions to depth maps. At the same time, each robot is mechanically unique, with a different number and orientation of arms, grippers, and sensors. Plus, the environments where data are collected vary widely.The MIT researchers developed a new architecture called Heterogeneous Pretrained Transformers (HPT) that unifies data from these varied modalities and domains.They put a machine-learning model known as a transformer into the middle of their architecture, which processes vision and proprioception inputs. A transformer is the same type of model that forms the backbone of large language models.The researchers align data from vision and proprioception into the same type of input, called a token, which the transformer can process. Each input is represented with the same fixed number of tokens.Then the transformer maps all inputs into one shared space, growing into a huge, pretrained model as it processes and learns from more data. The larger the transformer becomes, the better it will perform.A user only needs to feed HPT a small amount of data on their robot’s design, setup, and the task they want it to perform. Then HPT transfers the knowledge the transformer grained during pretraining to learn the new task.<h2>Enabling dexterous motions</h2>One of the biggest challenges of developing HPT was building the massive dataset to pretrain the transformer, which included 52 datasets with more than 200,000 robot trajectories in four categories, including human demo videos and simulation.The researchers also needed to develop an efficient way to turn raw proprioception signals from an array of sensors into data the transformer could handle.“Proprioception is key to enable a lot of dexterous motions. Because the number of tokens is in our architecture always the same, we place the same importance on proprioception and vision,” Wang explains.When they tested HPT, it improved robot performance by more than 20 percent on simulation and real-world tasks, compared with training from scratch each time. Even when the task was very different from the pretraining data, HPT still improved performance.“This paper provides a novel approach to training a single policy across multiple robot embodiments. This enables training across diverse datasets, enabling robot learning methods to significantly scale up the size of datasets that they can train on.&nbsp;It also allows the model to quickly adapt to new&nbsp;robot embodiments, which is important as new robot designs are continuously being produced,” says David Held, associate professor at the Carnegie Mellon University Robotics Institute, who was not involved with this work.In the future, the researchers want to study how data diversity could boost the performance of HPT. They also want to enhance HPT so it can process unlabeled data like GPT-4 and other large language models.“Our dream is to have a universal robot brain that you could download and use for your robot without any training at all. While we are just in the early stages, we are going to keep pushing hard and hope scaling leads to a breakthrough in robotic policies, like it did with large language models,” he says.

A faster, better way to train general-purpose robots

When a leading INDEX multi-spindle machine encountered significant challenges with chip removal, tool life, and coolant management, the introduction of a custom 3D-printed coolant ring provided an innovative solution that dramatically improved performance.The Challenge: Poor Chip Removal and Inconsistent Coolant CoverageThe machining process on an <a href="https://www.index-group.com/en_us/company/about-us/index-corporation" target="_blank" rel="noopener noreferrer">INDEX</a> multi-spindle machine was being compromised by poor chip removal, leading to shortened tool life and heightened fire risks. These issues stemmed from inconsistent coolant coverage, which was exacerbated by the machine’s compact design. Standard coolant nozzles were difficult to install due to limited space, and accessing tools with the probe was challenging. Moreover, operators were required to manually remove coolant lines during each tool change, introducing delays and variability that depended on the skill and experience of the operator.This situation not only reduced the efficiency of the machining process but also posed safety risks, making it clear that a more reliable and effective solution was needed. The Solution: A Custom Metal 3D-Printed Coolant RingTo address these challenges, the engineering team designed a custom metal 3D-printed coolant ring with internal channels optimized for efficient coolant flow. <a href="https://oneclickmetal.com/boldseries/" target="_blank" rel="noopener noreferrer">Metal 3D printing</a> was chosen for its ability to produce highly customized parts that precisely meet the stringent specifications required for this application.The coolant ring was engineered to withstand coolant pressures of up to 40 bar, resist oil, and ensure non-flammability. It was fabricated from non-toxic, non-corrosive materials to maintain an absence of contaminants throughout its life cycle. The design also ensured that the coolant ring was easy to install, space-saving, and allowed for easy probe accessibility.The coolant oil is directed through an adapter block into the inlet of the coolant ring. Inside the ring, the oil flows uniformly, being dispensed evenly from three openings to ensure precise delivery to the tool's tip. This design not only improved coolant coverage but also enhanced process stability, as the coolant ring could be removed and reattached independently of the operator, significantly reducing the time required for tool changes.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730200060177-Coolant+ring.jpg" style="width: 487px;" class="fr-fic fr-dib">The Benefits: Enhanced Efficiency, Safety, and Tool LifeThe introduction of the custom 3D-printed coolant ring brought numerous benefits to the machining process:<ol><li data-list-indent="1" data-list-type="bulleted">Better Chip Removal: The optimized design of the coolant ring ensured consistent and effective coolant flow, greatly improving chip removal and reducing the risk of tool damage.</li><li data-list-indent="1" data-list-type="bulleted">Increased Tool Life by a Factor of 20: With improved coolant coverage and chip removal, the tool life was extended dramatically, reducing the frequency of tool changes and lowering operating costs.</li><li data-list-indent="1" data-list-type="bulleted">Improved Process Stability: The ability to remove and reattach the coolant ring without relying on the operator reduced variability and enhanced overall process stability.</li><li data-list-indent="1" data-list-type="bulleted">Three Times Faster Tool Change Time: The streamlined design and ease of reattachment allowed for much quicker tool changes, tripling the speed of this critical process and further enhancing productivity.</li><li data-list-indent="1" data-list-type="bulleted">Safer Manufacturing Environment: The consistent coolant coverage and improved chip removal minimized the risk of fire, contributing to a safer working environment.</li></ol>Conclusion: A Custom Solution for Optimized PerformanceThe integration of a custom metal 3D-printed coolant ring into the INDEX multi-spindle machine represents a significant advancement in machining efficiency and safety. By leveraging the capabilities of metal 3D printing, the engineering team was able to overcome the limitations of traditional coolant systems, providing a solution that not only met but exceeded the demands of the application. This case study highlights the transformative potential of 3D printing in creating tailored solutions that enhance the performance and reliability of critical manufacturing processes.

In the world of precision machining, efficiency and reliability are paramount. This case study explores the challenge, solution, and benefits of integrating a metal 3D-printed coolant ring into the machining process.

Improving Efficiency with Customized 3D-Printed Coolant Rings

In a previous article, we talked about the benefits of&nbsp;<a href="https://ultimaker.com/learn/benefits-of-3d-printing-in-automated-packaging/">3D printing in automated packing</a> from a high-level overview outlining how the flexibility of additive manufacturing can save costs, simplify material components and improve the end-to-end process.More recently we’ve also hosted a webinar on how to&nbsp;<a href="https://ultimaker.com/learn/leverage-3d-printing-for-automated-packaging-with-real-life-applications/">leverage 3D printing for automated packaging with real life applications</a> (we highly recommend you check it out) and based on the interest generated and questions received during the presentation we wanted to provide you with a more comprehensive in-depth view over actual examples where 3D printing has made significant and sustained impact for several of our clients.So let’s dive into it!<h3>Automated Packaging Systems</h3>Leaning into the flexibility aspect previously covered, we want to be clear that 3D printing can be integrated in all types of automated packaging systems such as filling, sealing, labeling and wrapping machines, palletizing systems and many others. Clients such as Heineken, Krones, Ben&amp;Jerry’s, P&amp;G, Schubert, CocaCola, PepsiCo, Lego and Trivium to name a few, have all successfully integrated UltiMaker’s 3D printing solutions in their automated packaging processes and have all been part of our customer success stories.Below we’ll cover different wear parts, starwheels/sprockets, format specific tools such as infeed screws, LOTO/safety tools and ergonomic enhancements that have been made possible by 3D printing.Starwheel, infeed starwheel and sprockets:<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730169955965-UltiMaker-Packaging-starwheel-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib">Let’s start with one of the backbones of any production line, the starwheel used to drive conveyor/packaging lines, which was also featured on our&nbsp;<a href="https://ultimaker.com/learn/krones-optimized-3d-printed-parts-spares-for-customers-anywhere/">Krones success story</a>. The key requirements for a starwheel is for the part to have a high dimensional stability and high wear and tear resistance.When compared to traditional starwheels made out of POM, the 3D printed variant is cheaper (example part shown above was printed out of PET CF for around 44 €) and able to be optimized for each individual use case, which went coupled with the fact that these parts need to be replaced periodically, the fact that you can set the part to print at the end of your work schedule and have it ready the next day is a benefit that we simply don’t see with traditional sourcing or manufacturing methods.We also want to point out one of the cooler features that can be leveraged with 3D printing that is unavailable for other manufacturing processes (such as milling): dual material extrusion. The ability to print 2 different materials into one part, for example in an infeed starwheel, where the bulk of the part can be made out of a stiff high resistant material, and the outer wall can be printed out of a low friction material enables our clients to save up on material costs without compromising part integrity or functionality.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730169970195-UltiMaker-Packaging-infeed-starwheel-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib">Another benefit is the ability to optimize designs to use less material when printing, while part of this process is already accounted for when considering infill percentage (infill being the amount of material used to fill the internal volume of a part) the design process allows our clients to optimize the part further.One relevant example can be seen in the sprocket design below where the inside was printed out of a rigid technical material and a wear resistant material on the outside which allowed for reduced printing times while retaining part functionality and durability.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730169982608-UltiMaker-Packaging-sprocket-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib"><h3 id="isPasted">Inverter tunnels</h3>Product orientation changes during the packaging process, for example expiration dates on ice cream cups are typically printed on the bottom which is obviously not the natural orientation of the product during the filling process. As their name indicates, inverter tunnels are used to flip or invert products as they pass through the production line, designed to rotate items 180 degrees allowing them to be positioned correctly for the next step in packaging process (typically used for labeling, sealing or further processing).Traditionally, most inverter tunnels are made out by milling large blocks of POM material which is both wasteful and time consuming, but with 3D printing inverter tunnels can be optimized to be printed without supports as a single funnel system as seen below (for reference the part in the image cost €15 to print out of UltiMaker PLA Blue).<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730169996187-UltiMaker-Packaging-inverter-tunnel-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib">In case there are any concerns regarding the layer lines, please note that they do not cause any snagging or reduction in performance when compared to a traditional inverter. We’ll touch upon materials a bit later in the article but suffice to say that there is a plethora of low friction materials available that practically enable the item inside the tunnel to slide by itself.Inverter tunnels are also a prime example where the complex geometries of some products would make the part manufacturing through milling impossible due to the limitation in producing curved, non-uniform pathways. You can check out&nbsp;<a href="https://www.linkedin.com/posts/jeremy-evers-18a79bb1_3dprinting-additivemanufacturing-ultimaker-activity-7236632063146143744-upOx">this cool short presentation</a> made by our Senior Application Engineer, Jeremy Evers.<h3>Guide Rails</h3>One of the easiest things to optimize in a production line are product guide rails, whether it’s over longer distances or short corners; the flexibility that comes with 3D printing allows for the implementation of durable guide rails with several benefits over traditional options.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730170011020-UltiMaker-Packaging-guide-rails-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib">In the above example the guide rails were created for a bottle packaging line and printed in two materials, the tougher more rigid PET CF Gray for the structure and a more wear resistant low friction material on the inside as it would come in contact with the bottles. The best part in this use case is that when the wear strips need to be replaced you would only need to reprint them and slide them into place on the existing structure (for reference the part shown cost €25 to print with the cost of the wear strips alone being around €7-8).<h3>Infeed scroll/timing screws</h3>With previous parts we’ve touched upon the cost savings through reduced material use in manufacturing, faster lead times and design optimizations but what about instances where you are not able to source components for existing machinery? This was one of the challenges that our client Trivium faced when they were no longer able to source infeed worms to push aluminum cans forward on the production/packaging line.With UltiMaker they were able to quickly iterate and design their own infeed worms, 3D print them and ultimately print their optimized design using carbon reinforced nylon and keep their production rolling. For more information on how Trivium used 3D Printing to help replace parts in their automated packaging lines, you can also <a href="https://ultimaker.com/learn/trivium-3d-printing-replacement-parts-for-automated-packaging-lines/">check out this article</a>.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730170025902-UltiMaker-Packaging-indeed-scroll-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib">The ability to quickly design replacement parts for existing machines without compromising on part functionality or durability and have production back up and running within days without the need to externally source parts and get bogged down with delivery times is a critical benefit that becomes even more important when talking about remote locations such as Africa or South America. The best thing about UltiMaker’s 3D printing solution is that clients can send the digital part files to any connected location and have the part printed locally reducing the need of skilled onsite labor.<h3>LOTO safety tool</h3>At a glance the ability to optimize safety during maintenance with 3D printing by always having an affordable and adaptable safety LOTO (“lockout-tagout”) procedure for any valve, switch, latch, connector for any type of machine in bright visual colors cannot be overstated.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730170039983-UltiMaker-Packaging-LOTO-safety-tool-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib">For this application, it’s the flexibility that offers the biggest advantage as any potential risks that are identified can be resolved onsite, for example a chain cover that would normally require a lengthy delivery time, could easily be designed and printed onsite within hours optimizing worker’s safety.<h3>Wear parts</h3>From bottleneck grippers to can pushers, pack spinners to transition combs, 3D printing allows quick on-demand part replacement without taking up valuable warehouse space which as mentioned earlier is especially valuable when talking about remote plant locations.The intrinsic value of additive manufacturing in creating complex custom geometries means that not only can you replace individual parts but also complete assemblies creating a single, stronger part that is less likely to break or leak. One especially useful example we’ve seen is for top-loading machine (TLM) suctions assemblies.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1730170057682-UltiMaker-Packaging-wear-parts-wide.jpg" style="width: 100%px;" class="fr-fic fr-dib"><h3 id="isPasted">Materials</h3>One of the most common concerns when it comes to 3D Printing materials is whether it can hold up to the same standard as metal milled parts and we want to be clear, you can replace metal with plastic. Working with hundreds of companies we’ve noticed that applications made of metal are often overkill for a part’s mechanical needs, and because of the mentioned benefit of 3D printing technology being able to create geometries that are not achievable through machined metal, clients are able to create lightweight parts using a wide range of available materials that are fit for purpose.That being said, when thinking about what material to use, you have to know the requirements:<ul><li>Functional: e.g. strength, flexibility, durability, rigidity</li><li>Environmental exposure: e.g. temperature, humidity, chemicals</li><li>Weight and size constraints</li><li>Industry standards, material certifications, safety or regulatory material constraints. .</li><li>Aesthetic or surface finish: e.g. color, texture</li><li>How long should the material last under normal usage conditions.</li></ul>While a full list of available materials can be referenced on our&nbsp;<a href="https://marketplace.ultimaker.com/app/cura/materials">UltiMaker Marketplace</a> where we’re confident that you’ll find everything you need to best suit your needs, from FDA and EU Food Contact certified materials, medical grade polymers to PPS CF steel and aluminum replacement alternatives, we also wanted to present some of the recommended materials we’ve seen used by our clients in the food and beverage industry:<ul><li><a href="https://marketplace.ultimaker.com/app/cura/materials/Nicolas_Tokotuu/Polymaker_PolyMide_CoPA_2019">Polymaker CoPA</a> - Low friction coefficient, impact resistant</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/NE/IGUS_iglidurI150">Igus iglidur i150</a> - EU 10/2011 certified for food contact, self-lubricating, easy to print</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/NE/IGUS_iglidurI180">Igus iglidur i180</a> - High load and wear resistance</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/thiagomedeiros/LUVOCOM3F50588">Lehvoss 50588</a> - Magnetically detectable, FDA food safe certified, available in blue</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/FVI/kimya_PETG">Kimya PETG-S</a> - Easy to print, FDA food contact certified, available in blue</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/UltimakerPackages/UltimakerPPSCF">UltiMaker PPS CF</a> - Easy to print, extreme stiffness, high temperature resistance(HDT B of over 230℃ after printing)</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/UltimakerPackages/ultimaker_pet_cf">UltiMaker PET CF</a> - Easy to print, dimensional stability, high toughness, available in blue</li><li><a href="https://marketplace.ultimaker.com/app/cura/materials/NE/IGUS_iglidurI190">Igus Iglidur i190</a> - High temperature resistance, wear resistance</li></ul><h3>Change the game</h3>With overall costs increasing in the manufacturing and packaging industry and supply chain instability further contributing to volatile market dynamics we know that 3D printing can help you not just adapt, but change the game.All of our clients so far have benefitted from safer working environments, decreased lead-times and costs, improved warehousing and stock management, increased factory line uptime, faster time to market and increased overall equipment efficiency.

Leaning into the flexibility aspect previously covered, we want to be clear that 3D printing can be integrated in all types of automated packaging systems such as filling, sealing, labeling and wrapping machines, palletizing systems and many others.

Applications of 3D Printing in Automated Packaging

<section id="isPasted">When it comes to inspections in the maritime environment, the status quo has long been marked by challenges that impede efficiency and incur significant costs. Routine vessel inspections, vital for maintaining operational integrity, optimizing fuel efficiency, and ensuring safety underwater, have traditionally relied on divers or drydocking methods, both of which are inherently costly and time-consuming.The emergence of remotely operated vehicles (ROVs) promises a more accessible and cost-effective alternative, yet their usability has been hindered by the perennial problem of navigation beneath vessels' hulls.This article provides a comprehensive exploration of Dead Reckoning and the seminal work undertaken by Deep Trekker in mini ROV technology, with a particular emphasis on its potential to transform routine vessel inspections. The focus is on highlighting the implications for fuel efficiency, defect detection, and the cost-effective optimization of vessel maintenance.This innovative breakthrough was achieved by Deep Trekker’s pioneering work on Dead Reckoning technology. These latest achievements have the potential to advance underwater vessel inspections by providing a practical solution to the long-standing challenge of underwater navigation.<img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/3t6Sd0J8AmQJovMiFiUn2a/a62bd6232bd4c359e78a51496aabe8c7/Group_Glamor_Shot_crop1.jpg" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></section><section><h2>Applications of Dead Reckoning with Underwater Robotics</h2>Beyond just hull inspections, Dead Reckoning finds widespread application in the field of underwater robotics, where autonomous vehicles and ROVs navigate complex underwater environments for various tasks, including oceanographic research, underwater surveys, pipeline maintenance, and search and recovery, to name a few.In oceanographic research, ROVs equipped with Dead Reckoning systems can gather data on ocean currents, temperature gradients, water quality, and marine life distribution. By continuously updating their positions through Dead Reckoning calculations, ROVs can execute predefined survey patterns, enabling scientists to study ocean dynamics and ecosystem health.Similarly, in underwater inspections and maintenance operations, ROVs rely on Dead Reckoning to navigate complex underwater structures, such as offshore oil rigs and submerged pipelines.

Deep Trekker ROVs equipped with Dead Reckoning systems can systematically cover large search areas, narrowing down the search radius based on calculated positions and sensor feedback.Overall, the integration of Dead Reckoning with underwater robotics facilitates more effective navigation in challenging underwater environments, enabling a wide range of scientific, commercial, industrial, and humanitarian applications.</section><section><h2>The Significance of Dead Reckoning in Maritime Inspections</h2>Dead Reckoning is a key component in maritime operations, especially in underwater inspections, as it provides a fundamental means of tracking the position and movement of inspection equipment in underwater environments, such as ROVs. This enables inspectors to navigate, track, and collect data accurately in challenging subaquatic settings.When combined with other navigation aids and sensors, Dead Reckoning contributes to the safety, efficiency, and effectiveness of maritime inspections, ensuring that they meet their intended objectives.Here are some key points highlighting the significance of Dead Reckoning in maritime operations:<h3>Navigating Underwater Without GPS or Electronic Aids</h3>Dead Reckoning serves as a valuable alternative for navigation in GPS-denied environments like underwater regions where GPS signals may be obstructed or jammed. In underwater inspection scenarios, GPS signals are unavailable or unreliable due to the water's attenuation of satellite signals. Dead Reckoning can provide positional data when these systems are unavailable, allowing for underwater navigation without the assistance of GPS or optics in underwater environments.By harnessing a combination of inertial sensors, gyroscopes, accelerometers, and sophisticated algorithms, Dead Reckoning enables ROV operators to maintain accurate spatial awareness and navigate with confidence, irrespective of GPS availability.Operators can rely on Dead Reckoning’s positional data to guide the ROV along predetermined routes and conduct thorough inspections, all without the need for GPS or optics assistance.<h3>Maximizing Inspection Efficiency with Position Tracking</h3>Dead Reckoning enables inspectors to continuously estimate the position of Deep Trekker ROVs as they move underwater during inspections. This information is critical for ensuring that the inspection covers the intended area. When you know where you are, you know where you have already inspected, and you know where you need to go next. Up until now, there has not been an effective method for position tracking for underwater ROVs near ships.By integrating various sensors and algorithms, Dead Reckoning provides real-time feedback on the ROV's location, allowing inspectors to maintain control. By employing Dead Reckoning technology, inspectors can monitor the ROV's position relative to predefined waypoints or planned trajectories, ensuring that the inspection remains on course and covers all targeted areas effectively.<img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/76y0rV73H4Knpiq1h0jdGP/654a1b0426b093d3ada261e9c8bb45d7/gif-__ROV_MOVING_ALONG_HULL_OF_SHIP_WITH_TRACK_LINE_FOLLOWING.gif" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></section><section><blockquote>"Real-time position tracking enables inspectors to adapt to changing underwater conditions or unexpected obstacles, allowing for dynamic adjustments to the inspection strategy as needed."</blockquote>By maintaining accurate spatial awareness throughout the inspection process, inspectors can assess underwater assets, identify potential issues, and make informed decisions to optimize maintenance and repair activities.<h3>Enhancing Underwater Safety</h3>When working underwater, safety is a primary concern, both for the ROV operators and any accompanying divers - and knowing the location of the ROV and divers is essential for safety.Dead Reckoning helps inspectors ensure that ROVs or divers do not stray into hazardous areas, such as underwater structures, shipwrecks, or areas with strong currents. By utilizing Dead Reckoning for tracking the precise location of ROVs relative to underwater structures and currents, potential risks can be identified and avoided, minimizing the likelihood of accidents or damage to equipment.<h3>Optimizing Maintenance Strategies through Data Driven Insights</h3>Positional data obtained through Dead Reckoning improves the quality of inspection data, enabling inspectors to navigate ROVs to specific areas of interest. This targeted approach ensures that inspections focus on the most important areas, reducing the chance of missing essential details and improving data accuracy.<img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/5sM6RDNMt3mhw0FFcZ4pfK/55f0e7b543ed7c1e8d6b733f221c3aa0/gif-__LOOKING_UP_CLOSE_AT_SHIP_WITH_DEAD_RECKONING_TRACK_LINE_ON_SCREEN.gif" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii">This includes data such as the location of underwater structures, defects, or anomalies, which must be precisely recorded for effective analysis. Higher quality data can lead to more informed decision-making, potentially reducing the need for follow-up inspections that consume additional fuel and resources.The data collected by ROVs utilizing Dead Reckoning technology provides valuable insights that can optimize vessel maintenance strategies. By accurately documenting hull conditions and identifying areas requiring attention, ROVs allow maintenance teams to prioritize repairs, schedule cleaning operations, and implement proactive maintenance measures.This data driven approach minimizes downtime, reduces operational costs, and extends the lifespan of vessels, ultimately raising the bar for operational efficiency and profitability.</section><section><h3>Fuel Efficiency and Resource Management</h3>Dead Reckoning assists in efficient resource management by helping inspectors monitor the progress of inspections. It helps ROVs identify the optimal times to clean the ship, to ensure that the hull remains clear of biofouling. Fuel efficiency in maritime operations can be dramatically improved by regular inspections and keeping the hull clear of marine growth - which can potentially reduce fuel efficiency by up to 40% by creating drag from the rough surface.Minimizing fuel consumption not only saves money but also reduces the environmental impact of maritime operations. Dead Reckoning, by ensuring efficient maintenance schedules, contributes to sustainability efforts by reducing emissions associated with fuel burning.<img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/5wlYcwl6ZPnGvJmvXR1PbL/23d532b66f95008b4391b9f560b8b9d5/Wed-Aug-7-12-56-13-2019-hi-res-date-removed.jpg" alt="Hull inspection biofouling" class="fr-fic fr-dii"></section><section><h2>Integration of Dead Reckoning with Advanced Sensor Technologies</h2>Dead Reckoning technology is often integrated with advanced sensor technologies to further enhance the capabilities of ROVs during vessel inspections.
