To analyze and control the threedimensional motion of the fiveaxis steering gear manipulator, a mathematical model was constructed and the kinematics analysis was carried out. The control equation of the manipulator position steering gear was established. The threedimensional coordinates of the robot were determined by using LIDAR, and the visual recognition and positioning were carried out. In the Anaconda environment, Python language was used to write the core code of the end pose of the manipulator, and the range of parameters affecting the control accuracy of the manipulator were obtained by using LX-D15 digital steering gear to carry out simulation and test. The results show that the steering gear has the function of poweroff memory; the influence of each angle on the deviation is θ2、θ3、θ4、θ1、θ5 ordered from big to small; when the steering gear angle is θ1 within -45°~0°、θ2 within 45°~90°、θ3 within 0°~45°、θ4within -120°~-90°、θ5 within 135°~180°, the manipulator can achieve higher control accuracy
