Cost-efficient and suitable for many industries


For the future of robotic, automotive, and industrial markets, there is a need for reliable, robust, and cost-efficient solutions. Whether you want your robot to avoid collisions or you want to avoid scratching your rims on curbstones.

Our Ultrasonic 3D Echolocation sensor will help you to solve these tasks.

The sensor works by combining the time-of-flight principle of conventional ultrasonic sensors with triangulation and advanced signal processing algorithms.

ultrasonic 3D echolcation collision avoidance

“The game-changing technology can be used for collision avoidance of autonomous vehicles, people tracking in smart buildings and gesture control for consumer electronics.”

How does the sensor work?

Measurement cycle of an Ultrasonic 3D Echolocation Sensor:

  • Transducer sends out an ultrasonic pulse
  • Pulse is reflected by surrounding objects
  • Reflected pulse is received by an array of microphones on the sensor
  • Positions of the echoes are calculated as 3D coordinates, based on the different times when echoes arrive at the individual microphones
  • 3D coordinates are outputted at the end of each measurement cycle

Locate object positions in 3D, based on proven ultrasonic technology


Detect objects in the dark, through dust and dirt and in varying lighting conditions


Robust, energy-efficient, and suitable for a wide variety of industries


“Through powerful software, the sensor enables the precise detection of objects in real time […] This completely new method of positioning generates new ways […] of seeing the world via sound.”
