【正文】 in different environments. Low wages in China, plastic products industry, although still a laborintensive, mechanical hand use has bee increasingly popular. Electronics and automotive industries that Europe and the United States multinational panies very early in their factories in China, the introduction of automated production. But now the changes are those found in industrialintensive South China, East China39。 particularly in the hightemperature, high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as poor environment can replace the normal working people. Here I would like to think of designing a robot to be used in actual production. Why would a robot designed to provide a pneumatic power: pneumatic robot refers to the pressed air as power sourcedriven robot. With pressuredriven and other energydriven parison have the following advantages: 1. Air inexhaustible, used later discharged into the atmosphere, does not require recycling and disposal, do not pollute the environment. (Concept of environmental protection) 2. Air stick is small, the pipeline pressure loss is small (typically less than asphalt gas path pressure drop of onethousandth), to facilitate longdistance transport. 3. Compressed air of the working pressure is low (usually 4 to 8 kg / per square centimeter), and therefore moving the material ponents and manufacturing accuracy requirements can be lowered. 4. With the hydraulic transmission, pared to its faster action and reaction, which is one of the advantages pneumatic outstanding. 5. The air cleaner media, it will not degenerate, not easy to plug the pipeline. But there are also places where it fly in the ointment: 1. As the pressibility of air, resulting in poor aerodynamic stability of the work, resulting in the implementing agencies as the precision of the velocity and not easily controlled. 2. As the use of low atmospheric pressure, the output power can not be too large。 such as the atomic energy sector performs household hazardous materials used in the masterslave manipulator is also often referred to as mechanical hand. Manipulator mainly by hand and sports institutions. Task of hand is holding the workpiece (or tool) ponents, according to grasping objects by shape, size, weight, material and operational requirements of a variety of structural forms, such as clamp type, type and adsorptionbased care such as holding. Sports anizations, so that the pletion of a variety of hand rotation (swing), mobile or pound movements to achieve the required action, to change the location of objects by grasping and posture. Robot is the automated production of a kind used in the process of crawling and moving piece features automatic device, which is mechanized and automated production process developed a new type of device. In recent years, as electronic technology, especially puter extensive use of robot development and production of hightech fields has bee a rapidly developed a new technology, which further promoted the development of robot, allowing robot to better achieved with the bination of mechanization and automation. Robot can replace humans pleted the risk of duplication of boring work, to reduce human labor intensity and improve labor productivity. Manipulator has been applied more and more widely, in the machinery industry, it can be used for parts assembly, work piece handling, loading and unloading, particularly in the automation of CNC machine tools, modular machine tools more monly used. At present, the robot has developed into a FMS flexible manufacturing systems and flexible manufacturing cell in an important ponent of the FMC. The machine tool equipment and machinery in hand together constitute a flexible manufacturing system or a flexible manufacturing cell, it was adapted to small and medium volume production, you can save a huge amount of the work piece conveyor device, pact, and adaptable. When the work piece changes, flexible production system is very easy to change will help enterprises to continuously update the marketable variety, improve product quality, and better adapt to market petition. At present, China39。s main role is to control the robot according to certain proce
