Exploring the possibilities of supporting robot-assisted work places using a projection-based sensor system

Abstract

We explore different kind of functions which a projection-based optical safety system may provide in the context of physical human-robot interaction (HRI). A scenario will be presented in which a collaborative workbench equipped with a robot arm is augmented by overhead cameras and a projector. Beside safe collision avoidance, this system provides additional functions like information display and augmented reality for situation awareness, interaction, as well as 3D scene capturing. We were able to achieve these features without installing additional sensor hardware all while maintaining reliable workspace supervision.
