Munich-based startup Toposens is asserting the market launch of its first industrial 3D collision avoidance system for cellular robots based mostly on its proprietary 3D ultrasonic echolocation expertise. This represents a key milestone for the corporate following greater than seven years of R&D and product commercialization.

Addressing the unmet want for greater security of cellular robots in industrial settings, the Toposens 3D Ultrasonic Echolocation Sensor ECHO ONE and Toposens processing unit with subtle filters for 3D collision avoidance is now out there, having been run by rigorous industrial testing in real-life industrial eventualities with respected cellular robotic firms. This sort of “co-developing” of a high-tech product along with main tech corporations ensures highest ranges of efficiency for the commencing serial deployment.

Detecting the undetectable

With the autonomous car trade booming and cellular robots, similar to automated forklifts, AMRs and AGVs, experiencing exponential progress, the security of people and machines is stored on the forefront of producing efforts. The market has come to comprehend that 3D collision avoidance is a necessity, for the reason that compulsory 2D security LiDARs can solely ship two-dimensional knowledge output not matching highest security wants.

On account of their bodily properties, different 3D sensor programs, similar to LiDAR or imaginative and prescient have limitations of their notion capabilities when the optical situations of their atmosphere are unfavorable, or objects like forklift forks are near the ground. Consequently, they wrestle to detect objects effectively sufficient, making them an unreliable and inadequate collision avoidance resolution.

The standard one-dimensional ultrasonic sensor doesn’t ship the wanted knowledge for dependable 3D collision avoidance, as it could possibly solely measure easy distance knowledge (= time-of-flight), in comparison with the 3D level cloud the Toposens 3D COLLISION AVOIDANCE SYSTEM is ready to generate. The Toposens has a sensing vary of 10 mm – 3000 mm.

Re-defining robotic security

Looking for a technique to compensate these shortcomings and supply the market with a best-in-class 3D collision avoidance, Toposens has over the previous few years been working in the direction of a industrial model of its 3D Ultrasonic Echolocation Sensor to serve the necessity for a dependable cellular robotic 3D collision avoidance.

Primarily based on the precept of echolocation as seen in bats, Toposens ECHO ONE compensates the drawbacks of optical sensors by sound-based triangulation together with subtle noise-filtering software program. This in flip delivers sturdy 3D knowledge output in real-time for every impediment detected inside the absolutely adjustable warn- and cease zones. What’s extra, the zones can each be set to dynamically comply with a cellular robotic taking a left- or proper flip and alter to the pace of the car.

The sensor sends the obtained knowledge (echo reflections perceived by three microphones) in a 3D level cloud format to the Toposens processing unit which is supplied with superior 3D collision avoidance software program.

From there, relying on which 3D zone violations are detected, the Toposens PROCESSING UNIT triggers both a “decelerate” or “cease” command to the cellular robotic’s CPU. When no zone violations are detected, the cellular robotic drives on.

Bat imaginative and prescient versus unhealthy imaginative and prescient

“Having the ability to detect a number of difficult-to-detect obstacles reliably and in real-time, no matter environmental situations, allows us to offer next-level robotic security for our clients. Our expertise addresses the shortcomings of optical sensors, similar to LiDARs, which might fail to detect floor-based objects like forklift forks on the ground, in unfavorable lighting situations or clear or mirrored object surfaces. Receiving knowledge output in 3D, that means in x, y, and z coordinates, ensures essentially the most dependable degree of 3D collision avoidance”, says Tobias Bahnemann, CEO and Co-Founding father of Toposens and continues:

“Forward of manufacturing, we’ve got been co-developing and testing our Toposens ECHO ONE in pilot tasks and precise real-life set-ups with famend firms for nearly two years. This has put us able, from which we will now supply our clients a state-of-the-art, next-level robotic security system. With 3D collision avoidance capabilities lacking in present sensor options, the financial setback of broken items, and even costly manufacturing stops as a consequence of undetected obstacles, can significantly restrict the ROI of any cellular robotic system. This highlights the need for cellular robots to “see” their atmosphere utilizing a unique type of imaginative and prescient expertise – we name it “BAT VISION” and are delighted to now be transferring on to serial manufacturing.”

Toposens is now taking orders for its first industrial model of its 3D ultrasonic collision avoidance expertise.
