Radar for distance measurement, collision avoidance & positioning of mobile robots or drones.

More and more drones and mobile robots are being used for automation in places that are difficult to access or dangerous for people. These are often challenging environments with poor visibility, lots of dust, water vapor, vibrations or extreme temperatures. Robust sensor solutions are therefore necessary for the obstacle detection, distance measurement and positioning of these robots and drones.

With our powerful, reliable radar sensors, the exact position of drones and robots in relation to walls, vehicles, windows, pipes and other target objects or obstacles can always be reliably recorded, even in difficult conditions. The  application scope ranges from high-pressure cleaning with steam, dust or mud, inspections in dangerous environments with smoke, fire or extreme temperatures to spraying with cement and dyes. Our reliable radar solution ensures reliable distance measurement, obstacle detection, collision avoidance and positioning of drones and mobile robots even in the most adverse conditions. As a result, you will avoid avoid unplanned downtime and achieve from productive robot and drone operations.

Positioning & collision avoidance of mobile robots & drones - with radar

Your added value with radar


Prevent downtime, save costs.

  • Avoid collision-related downtime for your mobile robots and drones – with OndoSense radar sensors.
  • Minimal maintenance: Radar has no moving parts, works contactless and requires almost no cleaning.


Efficient robot & drone operations.

  • Our radar sensor ensures productive operations through quick positioning of mobile robots & drones.
  • The radar sensor's high measurement rate detects obstacles even when objects move quickly.


Safe positioning of robots & drones.

  • Our radar is weather-independent and also measures in heavy dust, rain, fog or harsh lighting conditions.
  • Radar measurements are not affected by wind or vibrations - unlike ultrasonic sensors.
