Abstract

A bionic tension and compression body knee joint for a biped walking robot belongs to the technical field of mechanical bionic engineering, and consists of a bionic double-ball component of a compression body, a bionic ball socket component and a ligament component of a tension body. Six-degree-of-freedom movement similar to a human knee joint is realized by guiding and limiting joint movement through a bionic ligament; the method is suitable for the biped walking robot, and low-energy-consumption, high-stability, high-flexibility and high-anthropomorphic movement can be achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical bionic engineering, and in particular relates to a bionic tension-compression knee joint for a biped walking robot. Background technique [0002] At present, the knee flexion movement of biped robot walking gait is facing the problems of high energy consumption and low stability. The knee joint of most biped robots is designed as a rigid hinge connection structure, which only has a single degree of freedom in the sagittal plane to realize the flexion and extension of the knee joint. In order to maintain the stability of the rigid hinge joint during motion, the drive system needs to provide real-time precise joint control, which undoubtedly requires the support of high-energy computing performance. At the same time, precise joint control needs to cooperate with the motor to avoid joint inertial motion during the movement, which also increases the energy consumption of the system. [0003] The ...
