Entering the automobile production enterprises, the production line composed of various welding robots and assembly robots runs accurately and efficiently. In the shopping malls, you can also see a wide range of cleaning robots, robot toys and so on. Robots have come out of science fiction and movie screens and come close to the lives of ordinary people.
The International Federation of robotics divides robots into two categories, industrial robots and service robots. Industrial robot is "a kind of automatic control, programmable and multi-functional actuator which is applied to industrial automation, including three or more programmable axes. It can be fixed or mobile". Service robot is "a kind of semi autonomous or fully autonomous robot, which can complete the service work beneficial to human health, but does not include the equipment engaged in production". It can be seen from the definition that the classification standard is the application situation of robots.
In recent years, the supply of industrial robots is on the rise in most industries. Robot service has a short history. The main difference in function is reflected in two aspects: one is the communication and cooperation with people; the other is to replace part of the work of human in complex environment.
