Its motion mechanism and maximal obstacle-surmounting capability of step-climbing forward and backward are mainly analyzed. Taking CUMT-II coal mine exploring robot prototype as an example, three dimensional relationship diagrams of the step height, the elevation angle and arms’ swing angle are drawn and the relation curves of slope gradients and the swing arms’ swing angles are drawn. The theoretical value of maximal obstacle-surmounting capabilities of the prototype are obtained and compared with the test results. And the best obstacle- surmounting performance and the corresponding centroid and swing arm p
