Researchers at the Fraunhofer Institute for Factory Operation and Automation IFF have developed a new projection and camera-based system intended to prevent collisions between robots and humans in the workplace.

The safety system employs conventional projectors and cameras, normally mounted on the ceiling, that project visible lines in the work area.

The camera immediately detects any intrusion by an individual. The robot would be instructed to decelerate at once, and optical and acoustic warning signals could be generated.
