Tailwind supplies visible navigation to drones in GPS-denied environments. Supply: KEF Robotics

Whereas autopilots have helped fly plane for almost a century, current enhancements in pc imaginative and prescient and autonomy promise to convey extra software-based capabilities onboard. KEF Robotics Inc. has been creating applied sciences to extend plane security, reliability, and vary.

Based in 2018, KEF mentioned it supplies algorithms that use digital camera information to allow autonomous flight throughout a wide range of platforms and use circumstances. The Pittsburgh-based firm works with designers to combine these autonomy options into their plane.

“Our firm’s mantra is to offer visible autonomy capabilities with any digital camera, any drone, or any pc,” mentioned Eric Amoroso, co-founder and chief expertise officer of KEF Robotics. “Being versatile and deployable to drones adjustments the mixing from days to hours, in addition to offering protected, dependable navigation,” he informed The Robotic Report.

“Consider us as a substitute for GPS,” mentioned Olga Pogoda, chief working officer at KEF Robotics. “The scenario in Ukraine reveals the problem of working with out GPS and true autonomy on the plane.”

KEF Robotics permits plane to function with out indicators

“We based KEF whereas coming into a Lockheed Martin competitors, which whittled 200 groups right down to 9,” recalled Amoroso. “The drones needed to be autonomous, which was an ideal take a look at case for modular, third-party software program.”

Since then, KEF Robotics has labored with the Protection Risk Discount Company (DTRA), which makes use of drones with a number of sensors to seek for weapons of mass destruction.

The corporate mentioned its Tailwind visible navigation software program can use stereo cameras for hazard detection and avoidance and that it makes use of machine studying to localize objects and full missions. That is significantly necessary for protection and safety missions.

“Our long-term objective is to permit an plane to finish complicated missions with a button push,” mentioned Pogoda. “An operator can present an overhead picture of a constructing and a common course.”

“Then, the autonomous plane can take off, fly to a location, and conduct a search sample,” she defined. “It might probably reroute based mostly on hazards on the best way, after which it might probably take photos or readings and are available again to an operator with out transmitting any indicators.”

KEF Robotics mentioned Tailwind, which might work at night time and long-range, GPS-denied flights, is in testing and on its option to availability. The software program has been validated at speeds as much as 100 mph and supplies closed-loop autonomous operations with drift charges of two% of the gap traveled. It has not but been certified for excessive climate or situations reminiscent of mud, fog, or smoke.

Integration necessary for modular strategy

As with different autonomous methods reminiscent of vehicles, a expertise stack with layers of capabilities from totally different, specialised suppliers is evolving for plane and drones.

“We’re seeing an attention-grabbing financial development in buying plane — producers are specializing in producing plane, and autonomy software program is complicated,” Pogoda famous. “Extra firms simply need to construct the plane with open interfaces to permit their clients so as to add capabilities after the preliminary supply.”

To facilitate a extra fast integration of superior autonomy, the U.S. Division of Protection’s Modular Open Programs Strategy (MOSA) is an initiative meant to save cash, allow sooner and simpler tools upgrades, and enhance system interoperability. KEF Robotics is following this strategy.

“MOSA says that every thing ought to be open structure, and the business should create instruments for every thing to work collectively,” mentioned Pogoda.

KEF Robotics has gained Small Enterprise Innovation Analysis (SBIR) grants to advance its expertise. How does modular software program determine in?

“The Protection Innovation Unit began pushing the MOSES philosophy that firms like KEF Robotics are embracing to quickly combine and innovate UAS [uncrewed aircraft system] expertise,” Amoroso mentioned. “We specialise in offering plug-and-play visible notion — expertise that’s costly and difficult to develop if you happen to’re additionally designing novel UAS. With MOSA, drone builders can let KEF Robotics concentrate on the reliability and efficiency challenges of visible notion whereas promoting a product with state-of-the-art autonomy.”

“The battle in Ukraine confirmed the crippling impacts of widespread GPS jamming and the utility of low-cost UAS,” he added. “It’s solely via MOSA will we consider that we are able to circumvent these threats affordably and at scale.”

“KEF affords two types of our answer,” mentioned Amoroso. “One is for these all in favour of GPS-denied navigation, collision avoidance, and goal localization. It’s a hardware-based payload that features methods to speak with an autopilot.”

“There’s additionally a software-only deployment for drones which will have already got such {hardware} onboard,” he added. “We comply with the MOSA philosophy for deploying our software program, together with others’ software program and digital camera drivers.”

For instance, KEF Robotics’ software program can take measurements and localize them, and a third-party structure can do customized object detection to identify smokestacks, Amoroso mentioned.

KEF Robotics collaborates with Auterion, Duality AI

“Earlier than KEF got here alongside, there was already an awesome neighborhood engaged on GPS-denied navigation, together with Auterion and Cloud Floor Management,” mentioned Amoroso. “However we had groups and corporations coming to us saying, ‘How can we get imaginative and prescient navigation to be plug and play?’”

In June 2023, Auterion Authorities Options partnered with KEF Robotics to mix AuterionOS with Tailwind for robots and autonomous methods.

“We’ve an awesome relationship with Auterion, which sees the identical core wants for ease of integration and reliability,” Amoroso mentioned. “We provide an instantiation of vision-based navigation, however we need to set it up for brand new gamers to fit in and supply their options extra simply, reminiscent of a lidar-based state estimator.”

“We began chatting early final 12 months about how we’d work with Auterion Enterprise PX4,” he famous. “Auterion wished to see a GPS-denied demonstration with its personal UAVs, and inside 18 hours, we obtained our system working with autopilot in a closed loop. We’re nonetheless doing demos with them and are all in favour of getting our software program working with Auterion’s Skynode.”

In November, KEF Robotics mentioned it was working with Duality AI’s Falcon digital-twin integration program to develop autonomy software program for a tethered uncrewed plane system (TeUAS) beneath a U.S. Military SBIR contract. Falcon can simulate totally different environments and drone configurations.

“It might probably simulate difficult eventualities like cluttered forests to check our software program and drones,” mentioned Amoroso. “That is just like how simulation might help autonomous autos increase security, with the good thing about with the ability to deploy totally different digital camera configurations and software program.”

Why decoupling software program and {hardware} is smart 

How does KEF divide duties between its methods and people of its companions? “The business has already aggregated round some requirements, however there are all the time customizations concerned to fulfill a buyer’s wants,” replied Amoroso.

“Some clients will say it’s OK to plug in our navigational messaging, and others want a companion pc that may monitor measurements or steering instructions to confirm or help their very own planning,” he mentioned. “It’s necessary to be versatile and to know early on what are the interfaces and to do drone demos to indicate that we are able to nonetheless execute a mission even when we don’t have full management of place or velocity.”

“However the benefit is, by decoupling autonomy from particular {hardware}, we are able to generalize our strategy and quickly combine on a brand new platform,” Amoroso mentioned. “If an plane has an open design, we are able to combine our complicated software program in lower than a day, begin flying, after which progress to a tighter integration at a buyer’s request.”

KEF Robotics is presently targeted on protection purposes, with a multi-aircraft demonstration of Tailwind for the Military deliberate for September 2024.
