One User Operation Versus Two Users Operation in Cooperative Remote Robot Systems

Abstract

In this paper, two users operation of a remotely-controlled robot possessing a force sensor by employing haptic interface devices is compared with one user operation for the cooperation work of moving an object under network delays through experiment. The objective is to find strategies that apply smaller force to the carried object. Our experimental results show that under large network delays, the two users operation outperforms the one user operation. We also show that when two users have different network delays, the user with the smaller delay can assist the other user.
