In general enterprises, as a factory for mechanical production, robots are required as equipment. However, many people do not know the structure and classification of robots. The general organization is divided into hands, arms, and trunk. As a company specializing in the production of robots, everyone learns the basics of robots together as follows:

　　1.Hand

　　The hand is mounted on the front of the arm. The inner hole of the arm is equipped with a transmission shaft, which can transmit the application to the wrist to rotate, stretch the wrist, and open and close the fingers.

　　The structure of the manipulator's hand mimics human fingers and is divided into three types: jointless, fixed joint and free joint. The number of fingers can be divided into two fingers, three fingers, four fingers, etc., of which the two fingers are most used. According to the shape and size of the object to be clamped, a variety of shapes and sizes of chucks can be equipped to meet the needs of the operation. The so-called hands without fingers generally refer to vacuum suction cups or magnetic suction cups.

　　Arm

　　The role of the arm is to guide the fingers to accurately grasp the workpiece and transport it to the desired position. In order for the robot to work correctly, the three degrees of freedom of the arm must be accurately positioned.

　　3. Torso The torso is a bracket for mounting arms, power sources, and various actuators.

　　2. Manipulators-Classification of Manipulators:

　　The types of manipulators can be divided into hydraulic, pneumatic, electric, and mechanical manipulators according to the driving method; they can be divided into two types of special manipulators and general manipulators according to the scope of application; they can be divided into point control and continuous according to the trajectory control method. Trajectory control robot, etc.

　　Manipulators are usually used as additional devices of machine tools or other machines, such as loading and unloading and transferring workpieces on automatic machine tools or automatic production lines, and changing tools in machining centers. Generally, there is no independent control device. Some operating devices need to be directly operated by humans. For example, the master-slave manipulator used for handling dangerous goods in the atomic energy department is also often called a manipulator. The application of manipulators in the forging industry can further develop the production capacity of forging equipment and improve working conditions such as heat and fatigue.
