Cobots, as a new kind of robots, is used to solve the problem that humans and robots can not work in the same space at the same time, so they have developed rapidly in the field of intelligent manufacturing. The original complex operation that only can be completed by human now can be completed in the cooperation between human and robot, so the labor cost and labor intensity is greatly reduced. Taking the establishment of intelligent flexible production line for automobile electrical product as example, the robot selection and simulation, control communication, production line layout, mechanical design and cost efficiency of cobots were discussed.It provides some suggestions for the selection of cobots for intelligent manufacturing.
