The robot arm design and check the overall dimensions of the parts, the characteristics and advantages of pneumatic technology, PLC control, the characteristics of the working principle of PLC control system of pneumatic manipulator . In this article , the robot arm for the overall scheme design . 1、 D etermin ing the coordinates of the mechanical arm forms , degrees of freedom, and the technical parameters of manipulator .2、 Designing the manipulator arm structure, calculat ing the rotary cylinder size and the size of the lift cylinder, and the selection and checking of the telescopic cylinder and the arm . 3、 Designing h olding type hand structure of mechanical arm and the robot arm's wrist structure .C alculat ing the driving moment of the wrist when needed and driving moment of the rotary cylinder .4、 Design ing the pneumatic system of mechanical arm and the map of mechanical arm pressure system working principle .5、 Because the mechanical arm is designed for general mechanical arm, analysis of the programmable logic controller ishow to control the pneumatic motor and mechanical can make use of the programmable controller according to the need to write a different program to control the manipulator, finally making the mechanical arm mov
