3D Predictive Simulation for Tele-operation Manipulator Based on VR

Time delay in communication channels of a tele-operation robot system conduces to instability and bad performance of system. In order to eliminate or reduce the effect of time delays , predictive simulation is adopted. Geometric model of the telerobot and the environment is constructed beforehand . Graphics simulation based on virtual reality can obtain area of the telerobot arrived at , movement states and the relation between the telerobot and the surroundings . It enhances the performance of telerobot system . This paper introduces a basic model of articulated manipulator, and expatiates the structure of VR for telerobot. The method that using VRML-JAVA technology based on PC to study the articulated manipulator is presented. The experiment result shows that using VR can predictive display motion track of robot and predictive control the distant robot.
