Sensors without sensors

The startup Rovi Robot Vision by three researchers from the Technical University of Munich has significantly simplified the complicated electronic sensor technology of robots. With previous industrial image processing solutions, robots only recognize the space around them or objects that they are supposed to grasp or process.

With industrial image processing from Rovi, robots can now also perceive their own body parts - without electronic sensors. Software thus replaces complex hardware sensors. Visual patterns printed on the robot are used to measure positions and movements. The Rovi software uses intelligent image analysis to calculate the robot's position in space, as well as its movements and joint positions.

Forces and torques are also measured using simple, passive, i.e. non-electronic elements such as foam or springs. The contact forces of the gripper or robot lead to characteristic deformations of these elements. The Rovi software measures these deformations using image analysis algorithms and uses them to calculate the contact forces. The data and statistics generated for Industry 4.0 from the robots and their applications are processed and evaluated on site or in the cloud. as
