World’s First Industrial Grade 3D Ultrasonic Collision Avoidance Sensor

RoboticToposens 3D Collision Avoidance System for mobile robots based on the proprietary Toposens 3D ultrasonic echolocation technology.

Addressing the unmet need for higher safety of mobile robots in industrial settings, the Toposens 3D Ultrasonic Echolocation Sensor ECHO ONE® and Toposens PROCESSING UNIT with sophisticated filters for 3D collision avoidance is now available, having been run through rigorous commercial testing in real-life industrial scenarios with reputable mobile robotic companies. This kind of “co-developing” of a high-tech product together with leading tech firms ensures highest levels of performance for the commencing serial deployment.

Detecting the Undetectable

With the autonomous vehicle industry booming and mobile robots, such as automated forklifts, AMRs and AGVs, experiencing exponential growth levels, the safety of humans and machines is kept at the forefront of manufacturing efforts. The market has come to realize that 3D collision avoidance is a necessity, since the obligatory 2D safety LiDARs can only deliver two-dimensional data output not matching highest safety needs.

Due to their physical properties, other 3D Sensor systems, such as LiDAR or camera have limitations in their perception capabilities when for example the optical conditions in their environment are unfavorable or objects like forklift forks are close to the floor. As a result, they struggle to detect objects well enough, making them an unreliable and insufficient collision avoidance solution. In fact, the leading cause of industrial accidents in 2022 has been identified as blocked vision, and the associated costs are forecast to amount to over 2.5 Bn $ by 2025 in over 50,000 factories being equipped with mobile robots. Also, the traditional one-dimensional ultrasonic sensor does not deliver the needed data for reliable 3D collision avoidance, as it can only measure simple distance data (= time-of-flight), compared to the 3D point cloud the Toposens 3D COLLISION AVOIDANCE SYSTEM is able to generate.

Re-defining robotic safety

 Trying to find a way to compensate these shortcomings and provide the market with a best-in-class 3D collision avoidance, Toposens has over the past few years been working towards a commercial version of its 3D Ultrasonic Echolocation Sensor to serve the need for a reliable mobile robot 3D collision avoidance.

Based on the principle of echolocation as seen in bats, Toposens ECHO ONE® compensates the drawbacks of optical sensors through sound-based triangulation in combination with sophisticated noise-filtering software. This in turn delivers robust 3D data output in real-time for each obstacle detected within the fully adjustable warn- and stop zones. What’s more, the zones can both be set to dynamically follow a mobile robot taking a left- or right turn and adjust to the speed of the vehicle.

The sensor sends the obtained data (echo reflections perceived by three microphones) in a 3D point cloud format to the Toposens PROCESSING UNIT which is equipped with an easy-to-configure advanced 3D collision avoidance software.
