Manipulator is now used as a indus trial robots in use, the control objectives often appear often in indus trial automation. Indus trial automation technology has gradually matured, as mature a technology line has been rapid development in industria l automation as a separate subject. Manipula tor application began to filter into welding, logistics, mecha nica l process ing, and other industries. Especially at high or very low temperatures, full of pois onous gases, high radiation case, robot in similar circumsta nces showed great use als o brings great convenience to the staff. Precisely because of this robot to get people's attention began to be a high degree of development. Labor rates, working conditions, labor intens ive aspects of promoting development.
