A supervision system for the intuitive usage of a telemanipulated surgical robotic setup

Abstract

This paper introduces the OP:Sense system that is able to track objects and humans and. To reach this goal a complete surgical robotic system is built up that can be used for telemanipulation as well as for autonomous tasks, e.g. cutting or needle-insertion. Two KUKA lightweight robots that feature seven DOF and allow variable stiffness and damping due to an integrated impedance controller are used as actuators. The system includes two haptic input devices for providing haptic feedback in telemanipulation mode as well as including virtual fixtures to guide the surgeon even during telemanipulation mode. The supervision system consists of a marker-based optical tracking system, Photonic Mixer Device cameras (PMD) and rgb-d cameras (Microsoft Kinect). A simulation environment is constantly updated with the model of the environment, the model of the robots and tracked objects, the occupied space as well as tracked models of humans.
