Predictive and Estimation Schemes in Sensor-Controlled Telerobotics
The paper discusses the problems that arise when sensorcontrolled robots in space are teleoperated from ground stations. Predictive 3D-computer-graphics presently seems the only way to successfully cope with the problem of transmission time delays of several seconds. Appropriate estimation schemes are outlined which include models of the delay lines the robot/ moving objects etc., and which derive the necessary corrections from sensory data as they are sent down from the spacecraft to earth. The space robot technology experiment ROTEX scheduled for the next spacelab-mission D2 is taken as a basis for the problem description.
