Play an increasingly important role in the move. Robot in China more generally, a wide range of applications Handling robot in wait for a wide range of application development in the area of todays industrial, medical, natural disasters, etc. However, the handling robot control system and the implementing agencies to play a decisive role in the work, Control and operative parts of great significance for the overall functioning of the robot work. The graduation project the main task is to solve the problem of implementing agencies and the control part of the, The graduation project adopts pneumatic transmission, programmable logic controller for moving the control part of the robot as the executing agency. For the overall design of this paper are mainly the following points, Must first determine the object handling robot designed to degrees of freedom of the handling robot, the robot parameters, and so on. This graduation project is calculated by calculating the outlet claws clamping force, The cylinder of the telescopic boom、Parameters of robot and so on. Then select the standard cylinder. Operative to draw pneumatic schematic, The control section according
