A camera based remote operating system of a 6×6 unmanned military robot vehicle has been developed for indoor test environment. The system consists of an operator console, a 6-axis motion platform (driving simulator), a 3-axis camera stabilizer, a real-time model for the unmanned military robot vehicle, and virtual environment for a bump course. In order to investigate the effectiveness of the developed system, bump course tests have been carried out. Operators driving ability has been also investigated with and without the control of the 3-axis camera stabilizer. Without the camera stabilizer, it is shown that remote operation is only possible with very slow speed, whereas with the camera stabilization control, operators can drive the vehicle with the moderate speeds.
