Abstract
Remote Mobile Investigator (RMI) robots are used by the Canadian Forces (CF) in explosive ordnance disposal (EOD) tasks. In the original RMI systems, the control station and the remote unit are linked by an eighty metres long, heavy (17 conductor) electrical cable spooled atthe control station which provides the control, video, and audio communications link between the two control and remote units. A multiplexer/demultiplexer system was developed to reduce the size and weight of the cable and extend the range of the communications link. Time-division multiplexing was used to send twelve control signals on one conductor from the controller to the remote unit, significantly reducing the number of required conductors in the link. An alternative, fiber opticlink for the control signals was also successfully demonstrated.
