Spraying robot is one of industrial robots. Industrial robots are multi-joint manipulators or multi-degree-of-freedom mechanical devices that are widely used in the industrial field. They have a certain degree of automation and can realize various industrial processing by relying on their own power energy and control capabilities. For manufacturing function, the spraying robot is also a multi-joint manipulator or a multi-degree-of-freedom machine device. Industrial robots include spraying robots, and spraying robots cannot represent the entire industrial robot.

Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemical industries. It can be said that current industrial robots can be widely used in various industries to improve industrial efficiency and industrial production safety. Industrial robots are composed of three major parts and six subsystems.

The three major parts of industrial robots are the mechanical part, the sensing part and the control part. The six subsystems can be divided into mechanical structure system, drive system, perception system, robot-environment interaction system, human-computer interaction system and control system.

Spraying robot is also a kind of industrial robot, and its composition is the same as the above industrial robot. The spraying robot is mainly composed of a robot body, a computer and a corresponding control system. The hydraulically driven spraying robot also includes a hydraulic oil source, such as an oil pump, an oil tank, and a motor. 5 or 6-degree-of-freedom articulated structure is mostly used, the arm has a large space for movement, and can do complex trajectory movements. The wrist generally has 2 to 3 degrees of freedom and can move flexibly. The wrist of the more advanced paint spraying robot adopts a flexible wrist, which can bend in all directions and rotate. Its action is similar to a human wrist, and it can be easily extended into the workpiece through a small hole to spray its inner surface.

To talk about the difference between spraying robots and industrial robots, industrial robots are a general term for systems that include industrial robots of various types of work, and spraying robots can only be used for spraying operations.
