with six degrees of freedom was proposed. Based on sand bearing characteristic compliance control was introduced to control system in horizontal and vertical movement directions at the end of the robot, and position control in attitude. With Matlab/Simulink toolbox, the system control models were established, and the bearing characteristics of rigid ground, hard sand, soft sand and softer sand were......
