Manipulator joint is a transmission form, suitable for operation close to the body. Motor drive, automatic Angle adjustment, elbow joint like hand, can achieve multiple degrees of freedom, more flexible movement, suitable for working in narrow space.

In order to make the manipulator joint design to meet the requirements of light weight, small volume, large bearing capacity and smooth transmission, we must choose the precision planetary reducer with large torque, large transmission ratio and moderate stiffness.

Working principle of manipulator joint:
The manipulator is a machine that imitates the movement of the human arm and can also be hung on the truss. This manipulator is called truss manipulator.
It consists of multiple beam and manipulator assemblies. One end of the manipulator is suspended from a horizontal module and the other end has a wrist and fingers.
The wrist can rotate with multiple degrees of freedom, and the fingers can grip objects, which humans can control directly or remotely.

However, the truss manipulator is only part of a variety of mechanical arms.
The precision planetary reducer used for manipulator joint activities has the advantages of high torque stiffness, but also has the advantages of good rigidity, can withstand overturning torque, output greater torque, overload correlation coefficient, impact resistance, small return, easy to install the system, a simple maintenance, etc..
