Manipulator Motion Principle and Deep Analysis of its Internal Structure

What is the inside of the manipulator? Is there any mystery?

Main structure of Pneumatic Manipulator

1. Structure of all parts of manipulator
The manipulator consists of a plurality of connecting rods and joints. The manipulator is generally composed of base, actuator, such as clamp, suction cup, etc., as well as joints and connecting rods between them. The manipulator can achieve arbitrary movement and steering within its range of motion. We generally call the movable joints as freedom degrees.

2. Air circuit element
Pneumatic manipulator's main air circuit components include swing cylinder, double cylinder, pen type cylinder and air source processing components.

3. Main sensors
The manipulator detects its own state, such as speed, position, acceleration, etc. through the internal sensor of the sensor, and then realizes the interaction between itself and the environmental information, such as distance, temperature and pressure. The environmental information is detected by the external sensor. Next, the controller selects the corresponding environment mode to command the manipulator to complete the task.

Manipulator working principle

Pneumatic manipulator is mainly composed of control system, drive system, actuator and position detection system. Under the control of PLC program, the actuator action is realized by pneumatic transmission.

The information of the control system will transmit the command to the actuator to track the action of the manipulator. If the action is wrong or fails, an alarm will be given immediately.

The actual position of the actuator is transferred to the control system by using the position detection device, and the actuator is finally moved to the designated position with a certain precision.
