Since manipulator being published, the corresponding each kind of difficult problem has been easily solved.Manipulator in space can be arrested, put, moving objects, flexible and diverse movements, can be applied to transform the production of variety of medium and small-volume automated production, is widely used in automatic soft line. PLC Design Manipulator mainly rely on the limit switch and solenoid valve control and promote them. The robot moves are all used to control power, air pressure drive. Its up / down, left / right shift and rotate left / right rotation using a double-double coil solenoid valve to promote completion of the cylinder pressure. The robot moves depend on the conversion limit switches to control the order and in accordance with a certain action. In the robots movement in the process of detection lights will be installed to detect movement of its start and stop. The design of the mechanical components are used in simulation of mechanical ha
