With the continuous improvement of technical level and production technology, the fields using automation equipment are also increasing. Any set of automated production equipment consists of the following parts:

　　1. Executive components

　　In the part of actuators, it includes electrical components, pneumatic components and hydraulic components. The differences between the three different actuators are limited to the drive method and the control medium. Actuators mainly include motors, electric cylinders, air cylinders, and hydraulic cylinders.

　　2. Sensor part

　　Sensors mainly include capacitive, inductive, photoelectric, magnetic induction, piezoresistive, etc.

　　3. Controller part

　　In addition to the robot part and PLC, if the actuator is a motor, there must be a corresponding dedicated stepper or servo controller.
