Paper Abstract

Humans can extend their capabilities to remote environments depending upon the remote teleoperation of mobile robots. The communication between the operator and the robot needs to be fast in order to quickly interact with the environment. However, the data transfer speed will slow down as either the data exchange rate increases or the Internet bandwidth decreases. Undesirable communication time delay invokes system instability. The purpose of this paper is to employ virtual reality technique to minimize the communication delay effect. A novel virtual tracker was developed and served to acquire the real position and orientation of mobile robot. The virtual reality scene is displayed on the remote computer, which needs only to use the data of the robot position and orientation. Instead of transmitting the huge amount of video stream from the robot to the client computer, the time delay can be ignored and system stability achieved.
