Topsens 3D Ultrasonic Collision Avoidance Sensor

The 3D ultrasonic sensor, designed for automotive and industrial applications, addresses the limitations of optical sensors through sound-based triangulation in combination with noise filtering software.

Toposens, manufacturer of safety equipment, announces the launch of a 3D ultrasonic anti-collision sensor for automotive and industrial vehicles. Called ECHO ONE, the product is based on proprietary 3D ultrasonic echolocation technology. The ECHO ONE and Toposens processing unit with filters to avoid 3D collisions is now available to order.

Based on the principle of echolocation as seen in bats, Toposens ECHO ONE addresses the limitations of optical sensors through sound-based triangulation in combination with noise filtering software. This in turn provides real-time 3D data output for each detected obstacle within the fully adjustable warning and stop zones. Zones can be configured to follow a mobile robot making a left or right turn and adapt 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 3D collision avoidance software.

From there, depending on the detected 3D zone violations, the Toposens processing unit triggers either a “slow down” or “stop” command to the mobile robot’s CPU. When no zone violation is detected, the mobile robot continues to drive.

“Being able to detect multiple difficult-to-detect obstacles reliably and in real time, regardless of environmental conditions, allows us to provide next-level robotic safety to our customers. Our technology addresses the shortcomings of optical sensors, such as LiDARs, which may not detect ground objects like forklift forks on the ground, in adverse lighting conditions, or transparent or reflective object surfaces.” , said Tobias Bahnemann, CEO and co-founder. by Toposens.

“Receiving data in 3D, i.e. in x, y and z coordinates, ensures the most reliable level of 3D collision avoidance.”
