Abstract
With the continuous progress of social production and people's accelerating pace of life, people are continuing to set new efficiency requirements. Robot technology has to continuously improve the equipment of rapid development, especially，because o Pneumatic manipulator systems have a lot of virtues such as its easy media sources，its none pollution to the environment，low price, easy maintenance, and
safe systems and reliability，has infiltrated into the industrial sector various sectors, in industrial development occupies an important position. The graduation project is to study the three degrees of freedom based industrial robot control system. The paper briefly introduces the concept of robot development and application prospect. Manipulator described in detail the hardware design and software design. One section describes the hardware design of a mechanical hand and the principle of selection of the various components, including cylinder and use the principle, the principle and use stepper motor, MCU selection, etc. The paper also describe the overall theory of manipulator based on the MCU. The software section describes the use of handheld devices and procedures for design, which mainly describes the use of handheld devices and their corresponding robot action.
Key Words：MCU; Pneumatic; Manipulator
