A research on tele-operation using virtual reality

Nowadays an idea of tele-existence or tele-presence that is based on the virtual reality technology has been proposed and is expected to be very effective for performing tasks in hazardous environments, such as a nuclear power plant. In our research we study the fundamental technique of tele-operation using virtual reality technology to manipulate the robot-arm in the nuclear power plant. This paper discusses quantitative evaluation of the properties of human in virtual space, i.e., the aggravation of the operability of the robot-arm manipulation system caused by the time lag in manipulating it, and the accuracy of stereoscopic viewing in virtual space.
