Now turned on the developmeogic controller) is in various special circumstances and under special conditions set for mechanical devind abegan to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home abroad to develop the PLC (programmable lon s, higcation begachnology line has been rapid development in industrial automation as a separate subject. Manipulator applin to filter into welding, logistics, mechanical processing, and other industries. Especially at high or very low temperatures, full of poisonous gaseh radiation case, robot in similar circumstances showed great use also brings great convenience to the staff. Precisely because of this robot to get peoples attentiogy has gractives Manipulator is now used as a industrial robots in use, the control objeoften appear often in industrial automation. Industrial automation technoldually matured, as mature a teol. This omation contrsign is mainly arm welding machine by PLC Autis slightly lower thad with restrictions on the manipulator development level n the international. The debeen applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed line that uses a robotic arm, and so on. oday, the high level of automation combinebecame que acontinues to develop as a factory automation standards. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unidvantages, such as: has good compatibility, wide availability, hardware is complete, and programming that can be mastered in a short time, so in the context of industrial PLC applications ubiquitous. Manipulator in many developed country agriculture and industry has big and succend ttechnology ahe rapid development of the trains, the success of PLC hardware software and simulation control win ssful development, now n still ct the
