It widespread applied in the flexible manufacturing system and the factory automation, and has the merits of high transportation efficiency, the energy conservation, the work reliable, the flexible transportation. It enormously enhanced production automaticity and production efficiency. Based on the analysis of the domestic and foreign AGV present situation and its development foundation, AGV with two wheel independent drive is designed. The content of the paper includes: design of mechanical structure and drive of the car, the choice of direct current servo motor, the hardware electric circuit of AT89C51 control system, the kinematic analysis, the software design of control system and the procedure of interpolation the circular arc. The designed car can realize the functions of independent movement, the path (circular arc, straight line) control and so on, and has achieved to travel along the hypothesis route.
