VR-based simulation on material handling remote operation for engineering machine

VR-based technology is a feasible idea for remote distance operation. Aiming the present material handling machine status, which is widely used in mine, Port, train station, etc al, in this paper, the scheme of VR-based Material Handling Remote Operating for Engineering Machine(VMHROEM) is presented. The frame of this system is build, and simulating theory is studied in details, which mainly includes object-oriented modeling, Modeling of virtual environment, modeling of human-computer interaction. In order to testify the theory, an experimental system considering the operator, computer, working machine, worked object, is given, which is integrated into closed loop by using mapping of human-computer and communication system. Here the interacting equipment consists of Dataglove, Spaceball, Shutter Glasses, and virtual environment is modeled by using, Worldtoolkit. While the real scene includes experimental fork that is the same scale as virtual working machine, barriers, worked object and other assisting facilities. The simulating results show that the operator can efficiently complete a remote distance operating task in the condition that he can be far away from the real scene.
