Traditional robot joint

Planar joint robot is a special case of cylindrical coordinate robot, and its shoulder joint and elbow joint are rotating joints.

I. Shoulder joint

Shoulder joint is the joint connecting the manipulator base and elbow joint, which is mainly responsible for controlling the rotation of the forearm part of the manipulator. Shoulder joint usually has rotational freedom, which can make the manipulator rotate on the horizontal plane, thus expanding the working range of the manipulator.

The design of shoulder joint needs to consider the overall stiffness and stability of the manipulator to ensure the stability and accuracy of the manipulator in the movement process.

Second, the elbow joint

Elbow joint is the joint connecting forearm and wrist joint, which is mainly responsible for controlling the rotation of forearm. The elbow joint usually has rotational freedom, which can make the manipulator rotate on the vertical plane, thus further expanding the working range of the manipulator. The design of elbow joint needs to consider the flexibility and stability of manipulator to ensure the fluency and accuracy of manipulator in the movement process.

Third, the characteristics of cylindrical coordinate robot

Cylindrical coordinate robots usually have three degrees of freedom, which are translation along the X axis, translation along the Y axis and rotation along the Z axis. The mechanical arm of this robot usually consists of a series of connecting rods, each of which can move or rotate along an axis. This kind of robot is also widely used in manufacturing.

Classification and application fields of robots

First, the classification of robots

Robots can be classified according to their motion modes, structural forms and working characteristics. Common robot types include cylindrical robot, spherical robot, polar robot, rectangular robot, articulated robot and so on.

Each type of robot has its unique characteristics and application fields, so it is necessary to choose the appropriate robot type according to the specific work requirements.

Second, the application field of robots

Robots are widely used, including manufacturing, service industry, medical industry, aerospace industry and so on. In the manufacturing industry, robots can be used for automated production lines, assembly, welding, handling and other work.

In the service industry, robots can be used to automate service processes, security and other work. In the medical industry, robots can be used for surgery, rehabilitation training and other work. In the aerospace industry, robots can be used for space exploration and satellite maintenance.
