Problems solved by technology
Robotic joints generally include a base, a first drive motor for driving the hand to rotate relative to the arm, and a second drive motor for driving the hand to swing relative to the arm. However, the first drive motor and the second drive motor generally It is located on the outside of the base, which makes the robot joints larger and causes the robot joints to be inflexible when in use

Description
technical field [0001] The invention relates to a robot joint applied to a robot. Background technique [0002] Robots can imitate certain movements of human hands and arms, and are used to grasp and carry objects or operate automatic devices according to a fixed program. The robot includes a hand, an arm and a robot joint, and the robot joint is used to connect the hand and the arm to each other so that the hand can move relative to the arm with multiple degrees of freedom. Robotic joints generally include a base, a first drive motor for driving the hand to rotate relative to the arm, and a second drive motor for driving the hand to swing relative to the arm. However, the first drive motor and the second drive motor generally It is arranged on the outside of the base, so that the volume of the robot joint is relatively large, and the movement of the robot joint is not flexible enough when in use. Contents of the invention [0003] In view of the above, it is necessary t...
