Abstract:
1. A ground-mobile robotic system comprising: an operator control unit (OCU) comprising: an unmanned ground vehicle (UGV) comprising: wherein the first OCU transmitter is configured to modulate a control data RF carrier and transmit the modulated control data RF carrier to the UGV via a second simplex RF channel such that the transmitted control data RF carrier is received by the first UGV receiver, wherein the first COFDM transmitter of the UGV is configured to multiplex the feedback data, the video data and the audio data, modulate multiplexed data RF carriers using a COFDM scheme and transmit the modulated multiplexed data RF carriers to the OCU via a third simplex RF channel, wherein the first COFDM receiver of the OCU is configured to receive the modulated multiplexed data RF carrier from the UGV, demodulate the received data RF carrier to extract the multiplexed data, and de-multiplex the extracted data into separate video data, audio data, and feedback data, and wherein the first COFDM receiver is further configured to provide the video data to a video display element, provide the audio data to an OCU loudspeaker, and provide the feedback data to the OCU processing element.
