A Teleoperated Bilateral Control System for Heavy Duty Tasks

A heavy duty power manipulator consisting of high reduction ratio joints is usually used in heavy duty tasks. When the heavy duty power manipulator is used as the slave manipulator in the teleoperated bilateral control system, the position control performance of the slave manipulator and the system stability tend to deteriorate due to the windup phenomenon caused by actuator saturation. KAERI has developed a teleoperated bilateral control system for the study of the remote handling of a spent fuel mockup bundle, which has an enhanced bilateral control algorithm improving the position tracking performance of the slave manipulator while compensating for the windup phenomenon. In this paper, the developed bilateral control system ...
