Manipulator has been widely used in industrial production because it can reduce labor intensity, improve the machining accuracy and reduce the number of dangerous operations manual operation. There are many kinds of control modes for manipulator trajectory. The PLC due to characteristics of low cost, simple structure, repeatable use, flexible programming ,it widely used in the control of the manipulator. This paper focus on the the software design and implementation. Through the simulation of the control system of manipulator, the PLC program design, debugging and running can achieve the expected control purpose and requirements, make the motion trajectory of manipulator in accordance with the relevant provisions. Based on the PLC programming, the manipulator can run in accordance with the requirements of running track.BackgroundWith the progress of science and technology, industrial production automation equipment demand is increasing day by day. Due to the reduction of labor intensity, improve the machining accuracy and less manual intervention operation risk, the manipulator has been more widely used in all walks of life.

Angle Indicator

A kind of digital compass based on magnetic resistance sensor was designed. The principle of the course angle measurement based on magnetic resistance sensor was analyzed, and it elaborates the scheme of course angle system design and implementation. FPGA was chosen as processor, and the embedded kernel was built up based on SOPC. The course angle measurement and digital display were realized. The error compensation was used in this system. The error analysis and contrast were given. This kind of course angle indicator is small volume and high precision. It can be applied to different carrier, and has high universality and practical value.
