Abstract

The invention discloses a robot joint jointly driven by double brushless direct current motors connected in parallel and a control method thereof, and relates to the technical field of robot joint devices. The robot joint jointly driven by double brushless direct current motors connected in parallel comprises two long connecting rods, wherein one ends of the two long connecting rods are connectedthrough a fixing threaded rod, the other ends of the two long connecting rods are correspondingly connected with one ends of short connecting rods through fixing bolts, each of the other ends of the short connecting rods is connected with one brushless direct current motor, motor drivers are correspondingly fixed to the outer end faces of the brushless direct current motors, and a connecting rod is arranged between the two brushless direct current motors. According to the robot joint jointly driven by the double brushless direct current motors connected in parallel and the control method thereof, the purposes that the structure is simple, the operation is convenient, the maintenance is simple, and the cost is saved are realized.

Description

technical field [0001] The present application relates to the technical field of robot joint devices. Background technique [0002] With the development of automation and informatization, the use of transmission devices to control the autonomous movement of robots has been vigorously developed. Robots can be applied to a wide range of scenarios, especially where the site environment is harsh and it is not convenient for manual operation. During the movement of the robot, there are certain requirements for the stability and flexibility of its joints. Traditionally, a single motor is used to drive the joints of the robot, and the movement speed is slow. At the same time, it has high requirements on the ground of the use environment, especially the robot with only bipeds. Contents of the invention [0003] The purpose of this application is to provide a robot joint driven in parallel by double brushless DC motors with simple structure, convenient operation, simple maint...
