Performance analysis of WLAN based mobile robot teleoperation

Abstract

The present paper demonstrates through experiments that the performance of a teleoperated robot system is strongly influenced by the quality of the communication environment, which in our case was a wireless LAN (WLAN). We analyzed the path following capability of a human operator in the case of a teleoperated robot, with haptic feedback. We investigated the influence of external WLAN traffic over the precision of robot tracking. The paper presents both the design of the bilateral teleoperation system for mobile robots and the experimental methodology for performance evaluation of teleoperation systems in open wireless networks.
