Rotating swing mechanism for robot arms, robot arms and robot

Abstract

The invention discloses a rotating swing mechanism for robot arms, the robot arms and a robot. A forearm shell is driven by a second motor of the rotating swing mechanism to surround the axis of an output shaft of the second motor to rotate so that rotating movements of human body elbows can be simulated; and the forearm shell has one degree of freedom, a rotating pulley is driven by a first motor of the rotating swing mechanism to rotate, and a fixed pulley is driven by the rotating pulley to rotate, so that a rotating seat rotates around a supporting shaft and further drives the forearm shell to rotate around the axis of the fixed pulley, thus swing movements of the human body elbows can be simulated, and the forearm shell has one degree of freedom. Accordingly, the elbow joints of the robot have two degrees of freedom.

Description

technical field [0001] The invention relates to the field of robots, in particular to a rotation and swing mechanism for a robot arm, a robot arm and a robot. Background technique [0002] With the advancement of science and technology, the research and application fields of robots are constantly expanding. Among them, the research and application of humanoid robots have received widespread attention and become one of the most active research hotspots in the field of intelligent robots. Humanoid robots are mainly developed through The robot arm completes the task, but many existing robot arms have shortcomings such as bloated joint structure and cumbersome control. [0003] For example, a light-duty service robot arm disclosed in Chinese patent (CN101780673B) uses a reducer and a motor to drive each joint action, making the structure of the robot arm complex. In addition, due to the limitation of the installation space of the robot arm, the reducer can only use micro The sm...

[0003] For example, a light-duty service robot arm disclosed in Chinese patent (CN101780673B) uses a reducer and a motor to drive each joint action, making the structure of the robot arm complex. In addition, due to the limitation of the installation space of the robot arm, the reducer can only use micro The small reducer drive realizes the arm swing function, but the price of the miniature reducer is higher
