Abstract

The invention provides a joint module and a robot leg. The joint module comprises a hip front steering engine, a knee front steering engine, a thigh structural member and a thigh connecting rod structure, wherein the hip front steering engine and the knee front steering engine are both arranged at a hip joint and are mutually fixed, output shafts of the hip front steering engine and the knee front steering engine are coaxially arranged, the thigh structural member is fixed to an output shaft of the hip front steering engine, the thigh connecting rod structure is fixed to an output shaft of the anterior knee steering engine, and the thigh connecting rod structure is used for driving the shank structural part to swing front and back. According to the joint module and the robot leg, the hip front steering engine and the knee front steering engine are arranged at the hip joint, the knee front steering engine does not need to be arranged at the knee joint, and the mass center of the joint module is increased. the output shaft of the hip front steering engine and the output shaft of the knee front steering engine are coaxially and fixedly arranged, so the structure is compact as much as possible, and the hip front steering engine and the knee front steering engine can support each other and correspondingly can bear larger bending moment.

Description

technical field [0001] The invention belongs to the technical field of intelligent machinery, and more specifically relates to a joint module and a robot leg. Background technique [0002] Robot legs can be used in various application scenarios such as humanoid robots and industrial robots. The legs of traditional robots are mostly connected in series to each servo to form a leg of the robot. As a result, the knee servo of the traditional robot leg is set at the knee joint, and the ankle servo is set at the ankle. Low center of mass, large moment of inertia, large steering gear torque, and difficult motion control. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a joint module to solve the technical problems in the prior art that the center of mass of the robot is low and the torque of the steering gear is large. [0004] In order to achieve the above object, the technical solution adopted by the present invention ...
