An all-terrain UGV (unmanned ground vehicle) based on six-wheel-independent-drive & skid steering is studied, and the advantages of 6×6 independent drive and skid steering in terms of obstacle surmounting ability and mobility are analyzed. An all terrain electric drive chassis based on remote control is designed and realized. The primary mobility performance and obstacle surmounting ability under specific structure are tested. Experimental results demonstrate that the UGV has better trafficability & geography adaptability than the 4× 4 ATV (all terrain vehicle).
