ABSTRACT

With the development of science and technology，automated production line is widely used in enterprise production, the manipulator as an important part of the automated production line also got considerable development and progress. Especially with the optimization of mechanical structures, pneumatic, hydraulic technology matures, control elements development and control of continuous improvement and innovation, the action of the robot accuracy, control, flexibility and reliability has been a marked improvement .Manipulator made outstanding contributions to reduce labor intensity and difficulty, to improve work efficiency and quality, reduce production costs, Robot development has played a pivotal role in the development of enterprises and income-generating. This issue is a mechanical, electrical, combined with the more closely the usefulness of project, The necessary discussion on the application of electrical, mechanical structure design, choice of control methods etc. Finally, summarizes the full-text, pointed out that the manipulator’s improvement measures, the application prospect and development direction.
