A commercial, battery-powered mine vehicle has been equipped for remote operation in coal mines. The vehicle is controlled by an operator from the remote station. Command signals originating at the remote station as well as visual and data signals originating on board the vehicle are relayed between the remote station and vehicle using a single coaxial line. This coaxial line is normally 2,000 feet in length and is reeled in and out from a drum mounted aboard the vehicle. This vehicular system has been tested in coal mines. Presently, the major limitation of this system is associated with fatigue failure of the splices in the coaxial line and lack of mobility caused by the three-wheel design.
