Force-based control scheme for stable contact motion in time-delayed teleoperation

Abstract

In this paper, force-based control scheme for stable contact motion is proposed. In recent days, haptics is one of major topics in robotics field. Especially teleoperation with haptic feedback has been studied for long years, but problem of time delay still exists. Time delay causes three problems : operational force, oscillating motion, and degrading of contact stability. Some conventional approaches tried to compensate delay of position by using compensator, however degrading of contact stability is not mentioned sufficiently. And conventional approach using some compensator degrade adaptability for target object. From this point of view, this paper aims to keep adaptability and improve contact stability in time delayed teleoperation.
