1、Hand Column Type Power MachineFollow with our country the rapid development of industrial production, rapidly enhance level of automation, implementation artifacts of handling, steering, transmission or toil for welding gun, spraing gun, spanner and other tools for processing, assembly operations fo
2、r example automation, should cause the attention of people more and more.Industrial robot is an important branch of industrial robots. It features can be programmed to perform tasks in a variety of expectations, in both structure and performance advantages of their own people and machines, in partic
3、ular, reflects the peoples intelligence and adaptability. The accuracy of robot operations and a variety of environments the ability to complete the work in the field of national economy and there are broad prospects for development. With the development of industrial automation, there has been CNC

However, the upper and lower common in CNC machining processes material, usually still use manual or traditional relay-controlled semi-automatic device. The former time-consuming and labor intensive, inef
5、ficient; the latter due to design complexity, require more relays, wiring complexity, vulnerability to body vibration interference, while the existence of poor reliability, fault more maintenance problems and other issues. Programmable Logic Controller PLC-controlled robot control system for materia
6、ls up and down movement is simple, circuit design is reasonable, with a strong anti-jamming capability, ensuring the systems reliability, reduced maintenance rate, and improve work efficiency. Robot technology related to mechanics, mechanics, electrical hydraulic technology, automatic control techno
7、logy, sensor technology and computer technology and other fields of science, is a cross-disciplinary integrated technology.Current industrial approaches to robot arm control treat each joint of the robot arm as a simple joint servomechanism. The servomechanism approach models the varying dynamics of
8、 a manipulator inadequately because it neglects the motion and configuration of the whole arm mechanism. These changes in the parameters of the controlled system sometimes are significant enough to render conventional feedback control strategies ineffective. The result is reduced servo response spee
9、d and damping, limiting the precision and speed of the end-effecter and making it appropriate only for limited-precision tasks. Manipulators controlled in this manner move at slow speeds with unnecessary vibrations. Any significant performance gain in this and other areas of robot arm control requir

Along with the development of industrial technology, produced independently according to the process control to achieve repetitive operation, using range is wide program control general manipulator, hereinafter referred to as general manipulator. General manip
