Study on the spray painting robot requires a combination of mechanical, electronic, information theory, artificial intelligence, biology and computer science knowledge, at the same time, its development has promoted the development of these disciplines. In this paper, a design of arm structure used in the painting robot, and complete the general assembly drawing and part drawing. Requirements for the mechanics analysis of the robot model, estimate required on each joint torque and power, complete motor and reducer selection. Secondly, from the motor and reducer connection and fixation of joint structure, design, and the mechanism of important connections check the strength.
