A kinematic diagram of the three-point (three-legged) wheel-legged robot and a construction of its layout, built in SolidWorks, are shown. A layered hierarchic control system of the robot is presented. Robot possible motion types are considered. An algorithm of walking over the flat surface is developed, movement phases of this algorithm are shown and a mathematical model of the robot motion is built in MATLAB. Chosen movement algorithm modeling was conducted; results of generalized coordinates changes in the robot joints, of the robot legs tips movement in the vertical direction and of the robot movement in its motion direction are obtained. Results of angular velocities and load torques changes in the robot jointsare presented through the example of the one of its legs. The analysis of the obtained results is made.
