Abstract<br />
This subject uses the software of making maps to pluck the tea-oil camellia and design anization to the manipulator. Including the anization, the worm gear worm decelerating device,the spur gear decelerating device;the hoist or anization, the barometric pressure cylinder hoists or lower device; the wave anization, atmospheric pressure device and four device ,the skids screw gearing,the anization , the slip spiral transmission device, the holding and unlock device, hold the rotation device ; PLC programme-controlled system, the relay - contact device control circuit, PLC exterior wiring, trapezoidal chart, instruction sentence the two-dimentional figures of anization with AutoCAD, draw the three-dimensional model of anization with Pro/E. Grasp AutoCAD and Pro/E drawing skillfully, integrate deeper understanding and know to mechanism, machine design and integration of machinery. <br />
