Lidar SLAM: The Ultimate Guide to Simultaneous Localization and Mapping

Based on an interview with Dr. Anita SenguptaImages of futuristic societies have long included high-tech urban air transportation for average citizens. With small drones becoming ubiquitous, such a future seems within reach. With the expansion of electric vertical takeoff and landing (eVTOL) aircraft, a significant portion of the population is looking forward to reduced congestion, shorter commutes, improved accessibility, and increased sustainability.Many also wonder what is delaying this future. When will we move beyond drones that deliver packages to air taxis that can carry human passengers across regions and urban areas for sustained periods?According to Dr. Anita Sengupta, CEO of Hydroplane, an up-and-coming hydrogen fuel cell powerplant manufacturer, the answer to these questions lies in solving four key challenges: power density limitations, competition from established aviation technologies, reliability requirements for autonomous flight, and sustainability concerns associated with combustion engines.<h2>Challenge 1: Power Density</h2>Non-electric VTOLs have been in use for decades, including helicopters and other aircraft such as the Bell Boeing V-22 Osprey. However, nearly all these aircraft have relied on internal combustion engines. As VTOL manufacturers shift their focus to electric powertrains to reduce air and noise pollution, they face the challenge of power density. That is, eVTOLs need sufficient power to run near-constant urban and regional flights from lightweight batteries.According to Sengupta, "In aviation, weight is everything. Batteries are heavy and can do short hops, but once you start talking about meaningful range and quick turnaround, the numbers just don't work."Currently, most eVTOLs can manage 20–30 minutes of flight time per charge and then have to spend significant time on the ground to recharge. "This might be enough to move people a limited distance within a certain metropolitan area, but not much more," Sengupta continues. "In urban air mobility, cargo, and regional flights, every minute and every pound counts. The time required to recharge frequently would significantly reduce the number of people a sky taxi could move in a given time period."<h3>Solution</h3>To overcome the power density challenges of electric batteries, the Hydroplane team has turned to hydrogen fuel cells. These cells generate electricity through an electrochemical reaction between hydrogen and oxygen, producing water, heat, and electricity."Hydrogen-fuel-cell–powered electric propulsion gives you much higher energy density," Sengupta says. "This makes it possible to fly farther and carry more, putting regional air mobility and urban flights easily within reach."In addition, Hydroplane's hydrogen fuel cells refuel quickly when needed, unlike the lithium-ion, solid-state, and sodium-ion batteries used by the current generation of eVTOLs. "For example, in the case of airport-to-city-centre shuttles, hydrogen electric would allow eVTOLs to cover a route and, then, with their rapid refuelling, turn around quickly and keep going," Sengupta explains.<h2>Challenge 2: Heavy Competition</h2>The next generation of air taxis faces stiff competition from a broad ecosystem of original equipment manufacturers (OEMs) of fixed-wing and rotary aircraft, as well as traditional VTOLs. Electric urban air mobility vehicles also face the daunting challenge of competing with combustion-engine aircraft, which offer broad capabilities and are time-tested, especially for the unique requirements of aviation.<h3>Solution</h3>Sengupta's strategy for this challenge is to avoid direct competition by emphasizing modularity. "We're focused on being the 'engine company' of the hydrogen-electric industry," she explains. "Our aim is to support—rather than compete with—OEMs. So, we have designed ourselves to be a drop-in replacement for both existing and new aircraft."Also, unlike other alternatives, Hydroplane's hydrogen fuel cell powertrain is explicitly designed for aviation."It's modular, liquid-cooled, and integrates high-efficiency power electronics [and an] axial flux motor, all powered by a fuel cell stack optimized for flight," Sengupta says. "The entire unit is designed for high specific power [and] compact packaging and meets aviation standards. We also have a [Controller Area Network (CAN)]-enabled software architecture that can be customized for various piloted and autonomous aircraft."So far, the Hydroplane team has tested its hydrogen fuel cell powertrain in a Piper Cherokee—a fixed-wing, propeller-driven aircraft—and US Army helicopters. This has provided rich, real-world data to improve the integration, operation, and reliability of Hydroplane fuel cells in eVTOLs and air taxis.<h2>Challenge 3: Reliability</h2>"As VTOLs move increasingly toward autonomy, it puts even more pressure on propulsion systems to be ultra-reliable," Sengupta explains. "For example, an autonomous sky bus service that runs the same route all day will require a propulsion system that demands only minimal downtime and predictable maintenance. And in terms of safety, with no pilot on board, it needs to have built-in redundancy in the event of an airborne fuel cell failure."<h3>Solution</h3>To address this challenge, the Hydroplane team has designed its hydrogen fuel cells to be more reliable than its electric counterparts. "We've built our fuel cells with fewer moving parts, fewer potential points of failure," Sengupta says. "This results in a significant reduction in downtime and maintenance that makes these eVTOLs a much more feasible, reliable option."She continues: "And of course, our hydrogen fuel cells also address safety concerns with built-in redundancy between modules. If one module has an issue, the other modules will ensure that you stay in the air."<h2>Challenge 4: Sustainability</h2>While many see automobiles as the worst offenders for air-polluting emissions, aircraft combustion engines have performed far worse in this area.Helicopters are notorious gas guzzlers that outperform most automobiles in emissions. For example, the Robinson R44, a helicopter commonly used in sightseeing, uses approximately 60L of fuel and produces an estimated 185kg of carbon dioxide equivalent emissions for every flight hour.<a href="https://www.mouser.com/blog/eit-2025-hydrogen-fuel-cells-power-future-of-evtols#_edn1" target="_blank">[1]</a> The Bell 206 JetRanger, however, dwarfs this output, with fuel consumption of 100L and more than 321kg of carbon dioxide equivalent emissions per flight hour.<a href="https://www.mouser.com/blog/eit-2025-hydrogen-fuel-cells-power-future-of-evtols#_edn2" target="_blank">[2]</a>Therefore, filling urban airspace with combustion-powered VTOLs that emit similarly high levels is untenable.<h3>Solution</h3>eVTOLs offer a significant reduction in polluting emissions because they produce none. However, they can still indirectly contribute to air pollution if their electricity is generated from non-renewable sources such as coal.The Hydroplane team's approach eliminates the need to draw electricity from the grid, generating its own energy in a fully emission-free process."We are proud to be able to help air travel take a big step forward in drastically reducing emissions," Sengupta says. "These advances will let us enjoy the benefits of this increased mobility without the anxiety and guilt that come with pollution."<h2>Conclusion</h2>According to Sengupta and the Hydroplane team, hydrogen fuel cells address four key challenges facing eVTOLs: the power-density limitations of batteries, competition from established aviation technologies, reliability requirements for autonomous flight, and sustainability concerns associated with combustion engines. Their aviation-specific, modular fuel cell powertrains offer higher energy density, rapid refueling capabilities, fewer points of failure, and zero emissions during flight. With successful testing already completed on aircraft such as the Piper Cherokee and on US Army helicopters, hydrogen fuel cells represent a viable path forward to making sustained urban and regional air mobility a practical reality.<h2>Dr. Anita Sengupta</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1769622016946-489563271_1217858757007749_8517622216328782586_n.jpg" style="width:100%px" class="fr-fic fr-dib" alt="Dr. Anita Sengupta, CEO - Hydroplane Ltd." />Dr. Anita Sengupta, CEO - Hydroplane Ltd.Dr. Anita Sengupta is an aerospace engineer, climate tech entrepreneur, commercial pilot, and professor at USC.

Hydrogen Fuel Cells Power the Future of eVTOLs

New Transport Canada RPAS regulations go into effect November 4, 2025.Among many coming changes, the industry is most excited about the prospect of enabling routine, low-risk BVLOS flight for those with the new Pilot Certificate: Level 1 Complex Operations (plus an organization or point person – an Accountable Executive – holding an RPAS Operator Certificate). The RPOC holder accepts overall responsibility for safe operations, including maintenance, training etc. In addition, the drone must meet TC’s safety requirements for Level 1 Complex Operations.But to fly BVLOS, the regulations require some sort of Detect and Avoid (DAA) system to avoid conflict with traditional low-flying aircraft. TC has provided <a href="https://tc.canada.ca/en/corporate-services/acts-regulations/list-regulations/canadian-aviation-regulations-sor-96-433/standards/standard-923-vision-based-detect-avoid" target="_blank">a standard</a> for vision-based DAA, but it has limitations including a max distance of 4 NM. For longer range BVLOS missions (and there are many applications) or other scenarios that don’t align with the standard, the operation must use a technology-based DAA solution.For an industry scrambling to take on routine, low-risk BVLOS operations, that’s a bit of a stumbling block. The cost of DAA systems (including ground-based radar) is prohibitive. And that’s why a recent LinkedIn post by <a href="https://www.linkedin.com/in/brian-fentiman-55024b111/" target="_blank">Brian Fentiman</a>, CEO of BlueForce UAV Consulting (and InDro’s Law Enforcement Division Consultant) recently caught our attention.“Canada’s drone industry is ready for BVLOS, but one major barrier remains: affordable Detect and Avoid (DAA) solutions,” he wrote. “Most DAA systems cost over $100k and can run into the millions. That’s not scalable.”InDro’s Training and Regulatory Specialist, Kate Klassen, agrees, saying “It might be the first time the regulations have been ahead of the technology.”Below: A look at the issue<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1761575455274-Detect-and-Avoid-scaled.jpg.webp" style="width:100%px" class="fr-fic fr-dib" alt="Detect and Avoid" /> <h3 id="isPasted">Electronic Conspicuity</h3>A far simpler and more cost-effective solution, argue many, would be a mandatory requirement for all crewed aircraft flying at lower altitudes to be equipped with an electronic system that constantly broadcasts information about its position and altitude. This generally means Automatic Dependent Surveillance – Broadcast Out, or ADS-B Out. It’s a vastly more affordable path to avoiding conflict between RPAS and low-flying aircraft, and the cost for RPAS operators for technology to detect these signals is inexpensive, accessible, and available.“The answer lies in Electronic Conspicuity (EC), low-cost ADS-B Out broadcast by crewed aircraft that lets RPAS operators safely detect and avoid traffic,” writes Fentiman. “The US, Australia, the UK, and New Zealand are already doing this. Canada must catch up.”Fentiman argues such a mandate would quickly open the skies to much-needed RPAS services, including:<ul><li>Search and Rescue</li><li>Energy Corridor Inspection</li><li>Emergency Response</li><li>Infrastructure Monitoring</li></ul>NAV CANADA mandated the use of this technology by traditional aviation flying in Class A Domestic Airspace in 2019, expanding it to include Class B in August of 2023. ADS-B is currently not required in uncontrolled airspace. There will be no further changes for some time to come.“The implementation of any subsequent Canadian ADS-B mandate in Class C, Class D or Class E airspace will occur no sooner than 2028, pending further assessment and engagement with stakeholders,” <a href="https://www.navcanada.ca/en/news/news-releases/ads-b-mandate-comes-into-effect-in-canadian-domestic-class-b-airspace.aspx" target="_blank">says NAV CANADA</a>.That’s part of the reason why the RPAS industry believes it’s critical to address this issue as soon as possible.“We don’t have a good RPAS-based solution for Detect And Avoid,” explains Klassen. “And size, weight and power restrictions are a challenging problem, which makes it hard to execute BVLOS missions under these regulations. That’s where Electronic Conspicuity comes in. If we expand the NAV CANADA mandate for ADS-B Out…then the only thing we need on the drone is a system to detect those signals.” <h3>Petition</h3>With the lack of an approved and affordable DAA system for drones themselves, many in the RPAS industry believe the simplest and most expedient solution is a broader mandate for ADS-B Out on all aircraft that fly below 500′. And so multiple industry partners (including the <a href="https://www.aerialevolution.ca/" target="_blank">Aerial Evolution Association of Canada</a>) have come together to create a petition to Transport Canada “to implement a nation-wide requirement for Electronic Conspicuity systems on all low-flying crewed aircraft that share airspace below 500 feet AGL with drones.”“It’s time to unlock safe and economical BVLOS drone operations in Canada,” writes Fentiman. “A national EC (Electronic Conspicuity) mandate would make Canada safer for both drones and general aviation.”You’ll find Brian’s full LinkedIn post <a href="https://www.linkedin.com/posts/brian-fentiman-55024b111_bvlos-rpas-dronesafety-activity-7384362846127792128-_b04?utm_source=share&amp;utm_medium=member_desktop&amp;rcm=ACoAAAeV1aUBl9vIw9w1aG6GtX4bsmUk5yhLt_U" target="_blank" rel="noopener noreferrer">here</a> – feel free to repost – and you can find a link to the petition <a href="https://indrorobotics.ca/enable-bvlos/" target="_blank">here</a>.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1761575793182-The-Path-Forward-EC-scaled.jpg.webp" style="width:100%px" class="fr-fic fr-dib" alt="The Path Forward" /><h3 id="isPasted">InDro's Take</h3>Like many in the industry, InDro embraces the coming regulations. But we share the belief that the lack of an affordable and approved DAA system will impinge RPAS operators during what should be a period of rapid expansion into routine, low-risk BVLOS flight. That’s why InDro is one of the partners pushing forward this petition.“Mandating Electronic Conspicuity for all crewed aircraft that share airspace with drones is a logical, practical and cost-effective solution that has the benefit of enhancing safety for traditional aviation, too” says InDro’s Kate Klassen.Once again, you can sign the petition <a href="https://indrorobotics.ca/enable-bvlos/" target="_blank">here</a>. And please spread the word.

Biologists have observed when and how these feathers deploy, but no studies have quantified the aerodynamic role of covert feathers during bird flight. Engineering studies have investigated covert-inspired flaps for improving engineered wing performance, but have mostly neglected that birds have multiple rows of covert feathers. The Princeton team has advanced the technology by demonstrating how sets of flaps work together and exploring the complex physics that governs the interaction.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzMwMTYzMTAzMjIwLVdpc3NhLXBsYW5lLWZlYXRoZXJzLWhlcm8tZm9yLXdlYi0yMDQ4eDExNTIuanBnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" style="width: 100%px;" class="fr-fic fr-dib">Princeton researchers at the Forrestal campus. Left to right: Ahmed K. Othman, Girguis Sedky, Hannah Wiswell and professor Aimy Wissa. Photo by Lori M. NicholsGirguis Sedky, postdoctoral researcher and the paper’s lead author, called the technique “an easy and cost-effective way to drastically improve flight performance without additional power requirements.”The covert flaps deploy or flip up in response to changes in airflow, requiring no external control mechanisms. They offer an inexpensive and lightweight method to increase flight performance without complex machinery. “They’re essentially just flexible flaps&nbsp;that, when designed and placed properly, can greatly improve a plane’s performance and stability,” Wissa said.A wing’s teardrop form forces air to flow quickly over its top, creating a low-pressure area that pulls the plane up. At the same time, air pushes against the bottom of the wing, adding upward pressure. Designers call the combination of this pull and push “lift.” Changes in flight conditions or a drop in an aircraft’s speed can result in stall, rapidly reducing lift.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzMwMTYzMTIzMjAxLWZvci13ZWItMDkxMjI0LVBSTi1XaW5kVHVubmVsLUxNTjI2NDcxLTE1MzZ4MTAzMC5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjk1MCwiZml0IjoiY292ZXIifX19" style="width: 100%px;" class="fr-fic fr-dib">The researchers explored the physics behind the flaps’ performance in a wind tunnel at Princeton.Wissa’s team designed a series of experiments in the wind tunnel at Princeton’s Forrestal Campus to understand how flaps mimicking the feathers would affect flight performance, especially near stall, which usually happens when the plane is at a steep angle, when covert feathers were observed to deploy. The tunnel allowed the team to examine the way different flap arrangements affected variables like air pressure around the wings, wind speed over the wing and vortices that impact performance.The team attached the covert-inspired flaps to a 3D-printed model airplane wing and mounted it in the wind tunnel, a 30-foot-tall metal contraption that simulates and measures air flow. “The wind tunnel experiments give us really precise measurements for how air interacts with the wing and the flaps, and we can see what’s actually happening in terms of physics,” Sedky said.The wind tunnel is equipped with sensors that read the forces felt by the wing, as well as a laser and high-speed camera that measure precisely how air is moving around the wing.The study uncovered the physics by which the flaps improved lift and identified two ways that the flaps control air moving around the wing. One of these control mechanisms had not been previously identified. The researchers uncovered the new mechanism, called shear layer interaction, when they were testing the effect of a single flap near the front of the wing. They found that the other mechanism is only effective when the flap is at the back of the wing.The researchers tested configurations with a single flap and with multiple flaps ranging from two rows to five rows. They found that the five-row configuration improved lift by 45%, reduced drag by 30% and enhanced the overall wing stability.“The discovery of this new mechanism unlocked a secret behind why birds have these feathers near the front of the wings and how we can use these flaps for aircraft,” Wissa said. “Especially because we found that the more flaps you add to the front of the wing, the higher the performance benefit.”Following the results of the wind tunnel experiments, the team moved outside the lab and into the field to test the covert-inspired flaps on a scaled model aircraft. Princeton’s Forrestal Campus was once an airport and still features an operational helipad. So, the researchers teamed up with Nathaniel Simon, graduate student in mechanical and aerospace engineering who researches drone flight, and demonstrated the technology in real-world conditions by equipping a radio-controlled (RC) airplane with covert-inspired flaps.The researchers worked with members of the Somerset RC model aircraft club to select a model plane. The researchers then modified the airplane body to outfit it with an onboard flight computer, and Simon drew on his experience piloting drones to fly it. They programmed the flight computer to stall the aircraft autonomously and repeatedly. Simon said it was amazing to see the flaps deploy in-flight and to see that they helped delay and reduce stall intensity, just as they did in the wind tunnel. “It’s cool to be able to collaborate in the shared space at the Forrestal campus, and to see how many areas of research this project touched,” he said.Sedky said that in addition to improving flight, their findings could be extended to other applications where modifying the surrounding fluid would benefit performance. “What we discovered about how coverts alter the airflow around the wing can be applied to other fluids and other bodies, making them applicable to cars, underwater vehicles, and even wind turbines,” he said.Wissa said that this study could open the door to collaborations with biologists to learn more about the role of covert feathers in bird flight, and that the results of this study will help form new hypotheses that can be tested on birds. “That’s the power of bioinspired design,” she said. “The ability to transfer things from biology to engineering to improve our mechanical systems, but also use our engineering tools to answer questions about biology.”<hr>The paper, “Distributed feather-inspired flow control mitigates stall and expands flight envelope,” by was published Nov. 20 in the Proceedings of the National Academy of Sciences. Besides Wissa, Sedky and Simon, authors include Ahmed K. Othman, and Hannah Wiswell, graduate students in mechanical and aerospace engineering. Support for the project was provided in part by the National Science Foundation.

Taking inspiration from bird feathers, Princeton engineers have found that adding rows of flaps to a remote-controlled aircraft’s wings improves flight performance and helps prevent stalling, a condition that can jeopardize a plane’s ability to stay aloft. 

Bird wings inspire new approach to flight safety

<h2>Why Connectors Are a Critical UAV Design Constraint</h2>Unmanned aerial vehicles (UAVs) have changed significantly over the past decade. Platforms that were relatively simple remote-controlled systems are now highly integrated airborne computers, carrying advanced sensors, communication modules, and autonomous control systems. Airframes are also getting smaller and lighter, and prioritizing payload efficiency and extended flight times. Miniaturization and performance expansion place pressure on every subsystem within the vehicle.The range of onboard electronic systems influences the design of the interconnect architecture that links them. Flight control units, inertial measurement systems, cameras, LiDAR modules, communication radios, and power distribution boards are required to exchange data and power reliably within a confined, weight-sensitive space. In this regard, connectors directly influence weight, reliability, signal integrity, and system resilience.<h1 id="isPasted"><a href="https://vat.aero/" target="_blank" rel="noopener noreferrer"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1779805369590-1779805369590.jpeg" width="576" height="432" class="fr-fic fr-dii" />Visionair Engine Starter Part. Image credit: visionair | Next Level Safety</a></h1>In UAVs, connectors are a non-trivial design choice. A marginal decision on connector selection can affect vibration resistance, introduce signal degradation, or add unnecessary weight. This article explores how connector design influences UAV performance in demanding environments and examines how <a href="https://www.harwin.com/">Harwin</a> addresses these requirements in next-generation UAV platforms.<h2>UAV Operating Environments and Mechanical Stress</h2>The conditions in which UAV connectors operate are quite different from those of terrestrial electronic systems. For instance, even small multi-rotor drones generate continuous vibration from their propulsion systems. Fixed-wing platforms introduce additional dynamic loads during take-off, maneuvers, and landing. These mechanical stresses are persistent throughout flight.Repeated micro-movements at contact interfaces due to vibrations can lead to fretting corrosion, intermittent signal interruption, or gradual loosening of the connection. In UAVs used for surveillance, mapping, or tactical operations, intermittent faults can compromise mission data without immediately presenting as a total system failure. Hence, robust mechanical retention is a primary design consideration.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1779805550182-1779805550182.jpeg" width="576" height="321" class="fr-fic fr-dii" />Landing Gear System of an Advanced Unmanned Aerial Vehicle. Source: Adobe StockShock loads are also common in UAVs. Hard landings and recovery operations expose connectors to sudden accelerations. In some tactical applications, UAVs may experience abrupt impacts during deployment or transport. Maintaining contact integrity under these transient loads is imperative to avoid any interruptions in power or signal paths.Similarly, dust, sand, moisture, and temperature fluctuations at altitude contribute to long-term reliability challenges. For instance, rapid temperature transitions can cause expansion and contraction of materials, stressing solder joints and mechanical interfaces. Therefore, connectors must be evaluated not only on their nominal electrical ratings, but on their mechanical and electrical stability under vibration, shock, and environmental exposure.<h2>Size, Weight, and Power (SWaP) Pressures in UAV Design</h2>Size, weight, and power (SWaP) constraints impact UAV design decisions. Every gram added to the airframe reduces payload capacity or shortens flight time. Small components, when multiplied across multiple subsystems, accumulate into a meaningful mass.Although connectors are small individually, a UAV may contain dozens of interconnects linking avionics boards, sensor modules, battery systems, and actuators. Selecting heavier connector systems where lighter alternatives would suffice can result in unnecessary weight. PCB real estate is another SWaP constraint as compact airframes limit board size, which pressures designers to increase component density. Connectors with higher contact density in smaller footprints enable more compact avionics architectures. However, reducing size introduces trade-offs. Smaller connectors must still provide sufficient contact force, electrical isolation, and mechanical robustness. If contact integrity is sacrificed for compactness, vibration-induced faults may increase.Similarly, connector selection also influences power distribution efficiency. High-current paths to motors, battery systems, and onboard compute modules require connectors capable of handling current without excessive resistive losses or thermal buildup. Therefore, lightweight connector systems that maintain mechanical retention and electrical performance are imperative for compact UAV designs as they provide tighter packaging of avionics without forcing compromises in reliability. <h1><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1779805369609-1779805369609.jpeg" width="576" height="321" class="fr-fic fr-dii" />Advanced Unmanned Aerial Vehicle (UAV) Components and Wiring. Source: Adobe Stock</h1><h2>Electrical and Signal Integrity Challenges in Compact Airframes</h2>Advanced UAVs integrate several electrical subsystems within confined spaces. For example, high-speed data links connect cameras and sensors to onboard processors, radio frequency modules transmit telemetry and video streams, and  power distribution networks deliver energy from batteries to motors, flight controllers, and auxiliary electronics. These mixed-signal environments create complex electromagnetic conditions.High-speed digital signals are sensitive to impedance discontinuities and electromagnetic interference (EMI). Cable harness construction influences electromagnetic performance and mechanical durability. The use of backshells, shield terminations, and braided cable shielding helps reduce susceptibility to EMI while providing protection against wear caused by movement and vibration within the airframe. Proper harness routing and shielding practices work together with connector geometry to maintain signal quality in densely packed avionics layouts.Moreover, poorly designed connectors can increase susceptibility to EMI. Contact plating materials and surface finishes also affect long-term electrical performance, particularly in vibrating or humid environments. In UAVs used for imaging or mapping, minor signal distortion can degrade data quality.Connector design with these considerations in mind can mitigate these issues. For instance, controlled contact geometry helps maintain consistent impedance for high-speed data lines. Adequate spacing and insulation help maintain electrical isolation in dense layouts. In some applications, integrated shielding features and robust grounding strategies reduce EMI susceptibility.<h2>Connector Design Features That Enable UAV Reliability</h2>Given the mechanical and electrical challenges described, certain connector design characteristics are valued in UAV applications. For example, secure mating mechanisms, such as locking features or screw retention, reduce the likelihood of accidental disengagement due to vibrations or shocks. Multi-point contact systems can improve electrical stability by providing redundant contact interfaces. Advanced material selection and optimized housing geometries help reduce weight without compromising structural integrity.High mating cycle durability is important for maintenance and modular system architectures. Many UAV platforms are designed with interchangeable payloads or field-replaceable modules. Connectors in these systems may be mated and unmated repeatedly during testing, upgrades, or repairs. Durable contact systems maintain performance across multiple cycles and reduce the wear-related failure risks.Companies with experience in the aerospace and defense sectors bring relevant expertise to UAV interconnect challenges. Harwin is a prime example that has developed connector families specifically engineered for high-reliability environments. For instance, Harwin’s <a href="https://www.harwin.com/hri-range/gecko">Gecko and Gecko-MT Series</a> connectors are designed for systems with strict SWaP limitations.

For instance, small tactical drones are deployed in field environments where maintenance opportunities are limited. Long-endurance systems operate at high altitudes for extended durations, subjecting electronics to temperature extremes and sustained vibration. Advanced autonomous and swarming systems complicate integration through distributed processing and inter-vehicle communication.Reliable connectors play an important role in these advanced designs. Sensor fusion systems rely on uninterrupted data exchange between cameras, radar units, inertial sensors, and onboard processors. A single intermittent connector fault can compromise data alignment or degrade navigation performance. Redundant system architectures require multiple parallel signals and power paths. Connectors in these systems are designed to ensure consistent performance across channels without significantly increasing weight. In swarming or networked UAV systems, compact and lightweight connectors facilitate distributed electronics, which allows designers to place processing nodes and communication modules throughout the airframe. This architectural flexibility enhances system resilience and scalability.<h2>Designing Connectors as Part of the Airframe System</h2>Connectors are treated as an integral part of the overall airframe system in next-generation UAV design. They influence weight, packaging density, signal integrity, and mechanical robustness. Lightweight, vibration-resistant connectors support the SWaP objectives central to UAV development. They help ensure consistent system behavior in demanding operational conditions by maintaining secure mating under continuous mechanical stress and preserving electrical performance in mixed-signal environments.Companies such as Harwin apply aerospace-grade connector design principles to emerging UAV applications, offering compact, durable interconnect solutions tailored to vibration-prone and weight-sensitive platforms. Engineers interested in exploring high-reliability connector technologies for UAV architecture can find further technical information and product specifications on <a href="https://www.harwin.com/" target="_blank" rel="noopener noreferrer">Harwin's website</a>.<hr /><h2>References</h2><ol><li>Harwin.

How does connector design influence UAV performance in demanding environments? Harwin explores high-reliability connectors for next-generation UAVs.

Lightweight, High-Reliability Connectors for Next-Gen UAVs

Electronic systems are becoming smaller, more powerful, and more densely integrated. Higher current levels, faster data speeds, tighter layouts, and harsher mechanical conditions are forcing engineers to rethink how connectors deliver both power and signal integrity without compromising reliability. In this interview, Ryan Smart, VP of Product at <a href="https://www.harwin.com/">Harwin</a>, shares insights into three major areas shaping advanced connector design, including effective shielding in high-reliability environments, higher-current compact connectors, and the importance of hybrid power-and-signal layouts.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzc3MzEwNzU0MTYzLVJ5YW4gU21hcnQsIFZQIG9mIFByb2R1Y3QgYXQgSGFyd2luLnBuZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width:100%px" class="fr-fic fr-dib" />Ryan Smart, VP of Product at Harwin<h2> </h2><h2> </h2><h2>Connector Reliability &amp; Shielding</h2>As electronic systems become more compact and densely integrated, maintaining signal integrity in electrically noisy environments is a major challenge for design engineers. Shielding has become a core aspect of connector design, particularly in high-reliability sectors such as aerospace, defense, motorsport, and industrial systems, where vibration, temperature cycling, and long service life are expected.We asked Ryan Smart about the practical challenges engineers face when designing shielded connectors and how Harwin approaches these issues in demanding applications.Wevolver Team: High-reliability applications demand robust signal protection. What are the biggest challenges engineers face today when designing shielded connectors?Ryan Smart: “I’d say the three biggest are the ability to manage EMI, to maintain shielding effectiveness and to ensure long-term reliability. Taking these in order, modern systems tend to be more compact and so have components more densely packed than they previously would, with noise sources sitting closer together. The shift to more compact systems also creates challenges in terms of shielding design – how do you ensure the performance while still also making them smaller, lighter and easier to assemble? And then there are the conditions in which they operate, for example the shield connection is likely to be undergoing constant vibration and/or temperature cycling, which require special measures to prevent failure from occurring. “Wevolver Team: As systems operate at higher data speeds and in electrically noisy environments, how is connector shielding improving to maintain signal integrity?Ryan Smart: “ There are several methods that can be used. For example, Harwin implements 360° shielding designs to reduce leakage and improve grounding continuity. But it’s much more than any one individual step and allowing operations to continue in such environments needs to be factored in right from the very start of a connector and shield’s conception. Material selection naturally plays a highly significant role, as does plating to improve conductivity and corrosion resistance. And then there are features such as latches and Screw-Loks that improve mechanical retention, which will also help prevent degradation of shielding performance over time.”Wevolver Team: From your perspective, what design considerations are most often overlooked when engineers specify shielded high-reliability connectors?Ryan Smart: “Definitely grounding paths, with some customers implementing these properly in the connector itself but failing to do so beyond it.After that, another area that we seek overlooked is the impact of termination quality and cable preparation on shielding performance. My final one relates to environmental factors that the connectors will come into contact with. Whether it’s an industrial system or a mil-aero computer, the connector and its shielding will be exposed to considerable vibration, moisture, and temperature ranges. These can all affect shield integrity significantly and designs must therefore take these into consideration to maintain the required performance and service life.”Wevolver Team: Harwin has developed connectors for demanding aerospace and industrial environments. How do your design principles translate into improved performance for such applications?Ryan Smart: “Harwin’s has a very strong track record here, and we are trusted by the military, by space agencies, by motorsport teams, and by industrial equipment manufacturers to cope with this. Material science and plating systems are vital in achieving this. For example, the Gecko G125 series of connectors have a vibration rating of 20G for 6 hours and implement a 4-finger beryllium copper contact design that provides a high spring force [BG6.1] to maintain connectivity through high vibration and shock. It additionally uses gold-over-nickel plating for high-reliability conduction over 1,000 mating cycles. And stainless-steel Screw-Loks and latching hardware are used for enhanced connections under stress.Testing is also essential, and it’s critical that all connectors are verified beyond basic compliance to simulate and ensure reliability in real-world operating environments.”<h2>Power Contacts &amp; High-Current Trends (10–100A)</h2>Designers are being asked to deliver more power in less space across industries such as UAVs, electrified vehicles, robotics, and industrial automation. The increasing reliance on battery systems, distributed power architectures, and compact system layouts is pushing connectors into higher current ranges, often between 10A and 100A, without increasing footprint. This introduces new thermal, mechanical, and materials challenges that need to be addressed at the connector design stage.We discussed with Ryan Smart about the trends driving this shift and the engineering trade-offs involved in designing compact connectors capable of safely delivering higher current.Wevolver Team: Many industries are pushing toward higher power density and electrification. What design and application requirements are pushing connectors toward higher current ratings, particularly in the 10-100A range?Ryan Smart: “This is absolutely the case and can be seen in systems such as UAVs, but also in the electrification of vehicles, as well as in robotics, and in industrial equipment too. Shrinking system size is common to all of these: UAVs obviously need to be lighter and smaller to travel further, but even industrial systems face this pressure with the more systems and more functionality needing to fit into the same facilities. In addition to this, there is an increased use of battery systems and distributed power architectures, which is pushing connectors to the higher current ranges. “Wevolver Team: What are the primary engineering trade-offs when designing compact connectors that must safely deliver high current?Ryan Smart: “Everything is a trade-off, but the top three are probably the balancing of contact size with space constraints; the need to implement thermal management without increasing the connector footprint; and the need to deliver increased durability and mating cycle performance but without adding bulk.”Wevolver Team: How is Harwin addressing challenges such as thermal management, contact durability, and reliability in high-current connector solutions?Ryan Smart: “Firstly, contact geometry can be better optimized to reduce resistance and heat generation. Beyond this, we are designing for thicker PCBs, which enables better heat dissipation and are therefore often a requirement in high current systems. From a materials point of view, our use of high-performance copper alloys and plating for long service life also plays a key role. And, as I said for vibration, validation for real-world conditions (including extremes) is vital to ensure our connectors meet our customers’ needs.”<a href="https://www.harwin.com/products?range=hri" target="_blank" rel="noopener noreferrer"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzc2ODgwNDE2OTEwLTE3NzY4ODA0MTY5MTAuanBlZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" width="624" height="446" class="fr-fic fr-dii" />Connectors fitted with backshells offer higher levels of durability, as well as EMC shielding</a><h2>Mixed Layout &amp; Hybrid Connectors</h2>Modern systems bring together motors, sensors, control electronics, and high-speed communication links within compact enclosures. Designers deal with power delivery, low-level signals, and high-speed data within the same tightly constrained mechanical layout. This can be seen in robotics, aerospace platforms, autonomous systems, and advanced industrial equipment, where reducing size and weight directly affects performance, efficiency, and system integration.Hybrid connectors address this challenge by allowing power, signal, and data lines to be consolidated into a single interface. This saves space, simplifies assembly, reduces cabling complexity, and lowers the number of potential failure points in the system. Ryan Smart talked about the applications driving hybrid connectors and the design challenges engineers face when combining multiple electrical requirements into one interface.Wevolver Team: In what types of applications are hybrid power-and-signal connectors becoming most valuable, and why?Ryan Smart: “While there are lots of applications, there are probably three core underpinning trends that dictate the need for hybrid connectors. First are applications where size and weight are critical, which would be aerospace and defense systems or drones. Second are those applications where both control signals and power are needed in tight spaces, and a good example of this is industrial automation systems. Finally, we have those systems where there is a need to combine motors, sensors, and data in one, and this can be seen in robotics and other autonomous systems.”Wevolver Team: What design challenges do engineers typically face when combining power, signal, and high-speed data within a single connector?Ryan Smart: “There is obviously a need to prevent electrical interference between high-current and sensitive signal lines. And maintaining mechanical strength while keeping the connector compact is also vital. But these come with the need to manage thermal effects from power contacts, which adds a whole world of complexity.”Wevolver Team: How is Harwin approaching hybrid connector development to help designers reduce space, simplify assembly, and maintain high reliability?Ryan Smart: “Harwin’s approach here comes down to designing for ease of assembly without compromising retention or durability. And this can probably be shown best if we look at a connector like the Datamate Mix-Tek, a 2.00/4.00mm pitch connector that delivers 3.3A for signal and up to 40A per contact for power. This retains many of the vibration resistance features of Gecko, allowing it to be rated up to 20G, but also brings in features such as a modular design that allow flexible pin configurations, and a 50Ω coaxial ganged contact for frequencies up to 6GHz. Bringing these onto a single connector enables smaller, lighter systems that are highly robust and offer the specifications to meet the performance needs of modern systems without compromising on size or reliability.”<h2>Conclusion</h2>Across shielding, high-current delivery, and hybrid layouts, Ryan Smart’s insights suggest that connector reliability depends on viewing the interconnect as part of the entire system rather than as an isolated component. Electrical performance, mechanical robustness, thermal behavior, materials, and assembly practices are closely linked, and overlooking any one of these aspects can affect long-term performance in demanding environments.The margins for error in connector specification and integration are becoming smaller as systems shrink. Grounding paths beyond the connector, termination quality, thermal management, and environmental exposure are all practical considerations that need to be addressed early in the design process. These factors influence not only signal integrity and current-carrying capability but also how well connectors withstand vibration, temperature cycling, and extended service life. Similarly, hybrid connectors can simplify layouts while maintaining performance and reliability by combining power, signal, and data into a single interface.Designing connectors for compact, high-power systems is less about any single feature and more about how multiple design decisions work together. Attention to these details enables connectors to meet the requirements of modern electronic systems without compromising reliability.

Designing for Reliability in Compact, High-Power Systems: Insights from Ryan Smart, VP of Product at Harwin

Radar has long been a foundational sensing technology in defense and critical infrastructure. It excels at detecting objects at distance, operating reliably in darkness, smoke, fog, and adverse weather where optical systems fail. Yet traditional radar systems can determine where an object is, but not necessarily what it is. Addressing this challenge is central to Physical AI, where systems must interpret sensor data and act on it instantly in real-world environments.The rapid proliferation of Unmanned Aerial Vehicles (UAVs) has introduced a new class of low-cost, highly mobile aerial threats. Commercial drones are widely available, inexpensive, and increasingly capable. At the same time, birds, debris, and environmental clutter continue to populate the skies. Distinguishing between a harmless bird and a hostile drone is no trivial problem. It is an operational requirement.<a href="https://brainchip.com/leadgen-radar-platform-registration/" target="_blank" rel="noopener noreferrer">BrainChip’s Radar Reference Platform</a> addresses this gap by embedding intelligent, low-power classification directly into the radar signal chain. Built around the Akida™ neuromorphic processor, the platform demonstrates how micro-Doppler analysis can enable real-time identification and classification of flying objects without relying on GPUs or cloud infrastructure, bringing Physical AI into operational radar systems.<h2>The Identification Gap in Modern Radar Systems</h2>Traditional radar systems detect motion and range using reflected radio waves. They provide position, velocity, and sometimes size estimations. While this can be good enough for many applications, in today’s aerial threat landscape, detection alone is insufficient.Security operators face three compounding challenges:<ol><li>Proliferation of UAVs introduces unpredictable aerial activity</li><li>Limitations of cameras and RF scanners in poor weather, night conditions, or spoofed environments</li><li>False alarm fatigue caused by radar systems unable to distinguish drones from birds or debris</li></ol>Cameras depend on line-of-sight visibility, while RF scanners depend on signal emissions that can be spoofed or suppressed. Radar remains the most robust sensing modality across conditions. However, without classification capability, operators must manually interpret signals or escalate unnecessarily.This results in wasted time, misallocated resources, and in defense scenarios, potentially expensive countermeasures deployed against low-cost targets. The missing capability is, therefore, intelligent classification at the sensor edge.<h2>Micro-Doppler: Extracting Identity from Motion</h2>When an object moves, radar detects Doppler shifts caused by its velocity. But complex objects, such as drones, produce additional fine-grained motion signatures. Rotating propellers create distinct micro-Doppler patterns embedded within the radar return.These micro-motions act as a fingerprint. Bird wingbeats differ from propeller rotations, debris exhibits irregular motion, and fixed-wing drones differ from quadcopters. The information is present in the signal, but extracting and interpreting it in real time remains an engineering challenge.Micro-Doppler classification requires continuous processing of high-resolution radar returns. Conventional AI hardware, particularly GPU-based systems, can perform this task but at a significant cost in power, size, and thermal complexity. Such architectures introduce cooling requirements, increased SWaP, and system-level constraints that limit field deployment.<h2>The Akida Radar Reference Platform</h2>BrainChip’s Radar Reference Platform combines:<ul><li>The Akida AKD1500 neuromorphic co-processor</li><li>A compact FMCW radar module</li><li>A micro-Doppler classification model optimized for <a href="https://brainchip.com/introducing-tenn-revolutionizing-computing-with-an-energy-efficient-transformer-replacement/">Temporal Event-Based Neural Networks (TENNs)</a></li><li>Raspberry Pi-based system integration</li></ul>This reference design demonstrates real-time classification of flying objects using neuromorphic computing at the edge, providing a validated blueprint for intelligent radar integration.<img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzc2MTc2Mjk2NjIzLUJyYWluQ2hpcCBSYWRhciBSZWYgUGxhdGZvcm0gTW9ja3VwLmpwZyIsImVkaXRzIjp7InJlc2l6ZSI6eyJ3aWR0aCI6OTUwLCJmaXQiOiJjb3ZlciJ9fX0=" style="width:611px" class="fr-fic fr-dib" />Image of the Akida Radar Reference Platform<h3>Event-Driven Processing for Radar Signals</h3>Akida processes radar data using TENNs and spatiotemporal CNN models, designed to capture both spatial and temporal features in dynamic signals. The architecture focuses on extracting meaningful temporal patterns from the signal without continuous, power-intensive computation.The input to the system is a time-frequency spectrogram generated from Frequency Modulated Continuous Wave (FMCW) radar data. Within this representation, micro-Doppler signatures appear as distinct textures formed by periodic micro-motions, such as propeller rotations or wingbeats. These patterns can be learned and recognized efficiently by models optimized for temporal signal interpretation.Micro-Doppler features manifest as repeating, time-dependent patterns, making them well-suited for TENN-based and spatiotemporal model architectures. This approach enables:<ul><li>Sub-2W total system power consumption</li><li>Low-latency inference directly on-device</li><li>Elimination of GPU dependency</li><li>Fanless, compact system design</li></ul>The result is a compact radar platform capable of classification within constrained power and thermal envelopes.<h2>Smart Classification Without Cloud Dependency</h2>A critical advantage of the Radar Reference Platform is complete on-device operation. All classification occurs locally with no reliance on cloud connectivity. This has significant implications, including:<ul><li>Comms-denied environments: The system operates independently without network access.</li><li>Data privacy and security: Sensitive radar data does not leave the device.</li><li>Low latency: Classification decisions occur immediately at the sensor.</li></ul>For defense and infrastructure monitoring, such autonomy is essential. In contested environments, transmitting data may reveal position. A system that can classify threats silently and locally preserves operational security while maintaining real-time responsiveness.<h2>Strategic Applications</h2>The Radar Reference Platform serves as a blueprint for deployments requiring real-time classification of motion signatures:<ul><li>Aerial Object Classification for Drones and UAVs: Micro-Doppler signatures enable reliable distinction between drones, birds, and debris in real time. This allows defense systems to classify targets early and avoid unnecessary countermeasures.</li><li>Defense and Early Threat Detection: On-device object identification supports real-time awareness in comms-denied environments. Systems operate silently, without data transmission, preserving operational security while maintaining responsiveness.</li><li>Automotive In-Cabin Sensing and Human Activity Detection: Radar can capture fine human motion patterns such as breathing or posture. This enables occupancy detection and health-related monitoring without cameras, preserving privacy.</li><li>Marine and Autonomous Platform Awareness: Radar-based classification helps distinguish between vessels, obstacles, and environmental motion in low-visibility conditions, supporting safer autonomous navigation.</li><li>Drone Countermeasures: Detection of propeller micro-Doppler signatures enables targeted response, reducing false alarms and improving response accuracy.</li></ul><h2>Ultra-Low SWaP for Portable Deployment</h2>Size, weight, and power are central constraints in field systems. The Akida-based radar platform delivers ultra-low SWaP characteristics:<ul><li>Compact FMCW radar module</li><li>Fanless architecture</li><li>Sub-2W total system power consumption, including Raspberry Pi 5, radar module, and Akida processor</li><li>Portable, man-deployable design</li></ul>This makes the system suitable for mobile early warning deployments, forward-operating environments, or temporary infrastructure setups. Conventional GPU-based solutions require active cooling and higher power budgets. The neuromorphic approach fundamentally reduces SWaP constraints while maintaining real-time classification capability.<h3>Reliability in Harsh Environments</h3>Radar inherently operates through smoke, fog, dust, and storms. By integrating classification directly into the radar platform, the system maintains robustness and performance.Unlike camera-based systems, it does not depend on visibility. And unlike RF detection systems, it does not rely on emitted signals that can be suppressed or spoofed. The reference design demonstrates validated, low-latency classification in a fully integrated stack. This reduces integration risk for product teams looking to embed intelligent radar into their solutions.<h2>A Blueprint for Intelligent Radar Products</h2>The Radar Reference Platform is not a standalone product. It is a complete, validated design that combines hardware, software, and AI modeling into a reproducible architecture ready for product adaptation.For defense contractors, infrastructure providers, and OEMs, it provides:<ul><li>Proven micro-Doppler classification capability based on TENNs</li><li>Integration framework around the AKD1500</li><li>Clear path from reference to deployment</li></ul>BrainChip’s ecosystem can adapt this design to specific product requirements, accelerating time to market while preserving low-power advantages.<a href="https://brainchip.com/leadgen-radar-platform-registration/" target="_blank" rel="noopener noreferrer"><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzc2MTc1NTEwOTUyLTE3NzYxNzU1MTA5NTIucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" width="602" class="fr-fic fr-dii" style="width:800px;height:197.75px" />BrainChip’s Radar Reference Platform Webinar April 20, 2026</a><h2>Redefining What Radar Can Do</h2>Radar has always provided visibility. The addition of intelligent classification transforms it into an autonomous decision-support system. Instead of reporting “an object detected at 300 meters,” intelligent radar can report “a quadcopter approaching.” That shift reduces false alarms, conserves resources, and increases operator confidence.By combining compact FMCW radar with neuromorphic processing, BrainChip’s Akida enables micro-Doppler classification at the edge, without GPUs, without cloud dependency, and without high power overhead. This moves radar systems beyond detection toward real-time understanding at the edge.For an exclusive deep dive into BrainChip’s Radar Reference Platform, check out the upcoming Webinar, April 20th: <a href="https://brainchip.com/leadgen-radar-platform-registration/">https://brainchip.com/leadgen-radar-platform-registration/</a>

Adding Intelligence to Radar with the BrainChip Real-Time Micro-Doppler Classification

Intelligent Radar Classification with Neuromorphic AI

Canada’s new budget was unveiled Monday, November 4.Delivered by Finance Minister François-Philippe Champagne, there was a lot of focus on technology and defence – both for global competitiveness and to reflect a changing geopolitical world. CBC carried extensive live coverage of the event, which included an interview on the program The House with InDro Founder and CEO Philip Reece on a panel.The headline for the tech sector? A massive investment in defence spending, which includes dual-purpose technologies, meaning they can be utilised both for defence and industrial/civilian purposes. And the money? It’s big, including $81.8B over five years to rebuild, rearm, and invest in the Canadian Armed Forces.Here’s a breakdown:<ul><li>$17.9 billion over five years to expand Canada’s military capabilities including investments in additional logistics utility, light utility, and armoured vehicles, counter-drone and DRONE long-range capabilities, and domestic production, among other investments.</li><li>$6.6 billion to support the Defence Industrial Strategy</li><li>$6.2 billion over five years to expand Canada’s defence partnerships, including military assistance to Ukraine.</li></ul>The Defence Industrial Strategy is new – and Canada’s first-ever such strategy. Details will be released in the coming months. But during the recent GCXpo in Ottawa, <a href="https://indrorobotics.ca/gcxpo-2025-another-successful-showcase-of-cutting-edge-technology/" target="_blank">Defence Minister David McGuinty</a> explained that it will lean heavily on Canada’s technology innovators.“This is what I do know, and for sure: I know that at the heart of the strategy is you. The innovators, the investors, the risk-takers, the entrepreneurs, and the startups. You’re going to help us develop the dual-use technologies that are going to shape the future of defence and security,” he said.Below: Dual-purpose technologies, such as our Sentinal inspection robot, could play a significant role in Canada’s Defence Industrial Strategy.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1764090883389-DSC02754-980x655.jpg+copy.jpg" style="width:100%px" class="fr-fic fr-dib" alt="Inspection Robot Sentinel" /> <h3 id="isPasted">Canada Strong </h3>It was clear from Finance Minister François-Philippe Champagne’s opening remarks that this would be a very different kind of budget.“The world is undergoing a series of fundamental shifts at a speed, scale, and scope not seen since the fall of the Berlin Wall,” he said.“The rules-based international order and the trading system that powered Canada’s prosperity for decades are being reshaped – threatening our sovereignty, our prosperity, and our values….Budget 2025 represents the largest defence investment in decades.”And perhaps most revelant for this sector?“With our new Defence Investment Agency and Defence Industrial Strategy, we will build up Canada’s defence industry – strengthening Canadian businesses and supporting Canadian workers…We will further build our security and defence capabilities, right here at home – creating new jobs for our engineers, technicians and scientists in sectors such as aerospace, shipbuilding, cybersecurity, and AI.”In many ways, the budget signified that Canada is at a critical turning point. And while it wasn’t all focused on defence and innovation, there was a striking emphasis on these areas. And that means challenges – and opportunities – right across the entire technology sector.“This is about more than one company; it’s about building a Canadian defence ecosystem,” says Reece. <h3> </h3><h3>Innovation in a Changing World</h3>The world is changing in unprecedented ways. The stability of geopolitics we’ve traditionally enjoyed is now much more uncertain. Significant conflicts, using newer technologies, are in the news every day. So it was no surprise the Canada Strong budget emphasized this country needs to advance its capabilities.Following the budget, CBC’s The House interviewed a panel that included InDro Robotics Founder/CEO Philip Reece for his reaction from the technology sector. He started by touching on the budget’s potential to help grow SMEs, which are really the backbone of bringing new technologies to the fore.“This budget is a strong start for that,” he said. “Now…we need the Canadian government to follow through and allow innovators like InDro – and the many others that are out there – to really compete and become those global companies that we deserve to be.”Part of that plan will be contained in the forthcoming Defence Industrial Strategy, which will be released in the months to come. As previously hinted by Canada’s Minister of Defence, this strategy will rely heavily on technology entrepreneurs ranging from startups and SMEs through to major corporations. InDro Robotics invents and manufacture technologies that have already assisted the Department of Defence and have carried out work directly for the Ministry. (Most recently, InDro and partner CHAAC Technologies carried out a demonstration for the DoD of an <a href="https://indrorobotics.ca/indro-partners-with-montreals-chaac-on-landmine-detection-project/" target="_blank">AI land mine detection project</a>that fuses drones, ground robots, and a neural network.)Devices like our dual-purpose Sentinel inspection robot can be put to work in the field for reconnaissance, and our InDro Cortex greatly enhances the capabilities of a wide range of existing devices – including military vehicles and drones. We also have extensive expertise in customised drone and Counter-UAS technologies.“It’s the same kind of technology now that can be rapidly swapped over to defence,” Reece told The House. “And we have seen that sort of build over the last couple of years, but it needs to build faster. “InDro Robotics is ready to deliver on Canada’s defence vision. We have the tech, the talent, and the ambition, now we need a clear path from government that allows us to grow and meet the moment,” says Reece.Below: Philip’s interview on CBC’s The House, followed by an image of our Cortex – a dual-purpose InDro innovation that can be used for defence, industrial and civilian purposes<iframe width="640" height="360" src="https://www.youtube.com/embed/Gq7kdGZBzi0??si=DTWJOhV-YHgE7-oV&amp;wmode=opaque&amp;rel=0&amp;enablejsapi=1&amp;origin=https://www.wevolver.com" frameborder="0"> </iframe><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1764090997953-Image-38-scaled.jpeg.webp" style="width:100%px" class="fr-fic fr-dib" alt="InDro Cortex" /><h3 id="isPasted">InDro's Take</h3>It is indeed a changing world. And we’re pleased (and relieved) to see the Government of Canada recognise the important role that technological innovation will play in our future sovereignty and security. InDro Robotics, and many other tech companies in this country, are ready to answer this call.“The Canada Strong budget marks a pivotal moment for Canada’s defence and economic resilience,” says InDro Robotics Founder/CEO Philip Reece.“InDro Robotics welcomes the increased investment and urges the government to now deliver a clear strategy to help Canadian businesses grow into true global leaders, capable of supplying the men and women of the Canadian Armed Forces with the tools and equipment they need and supporting Canada’s trade diversification goals. It is indeed a challenge, and we are up for it.”We look forward to the forthcoming details of Canada’s Defence Industrial Strategy, and will update you at that time.
