Problems solved by technology

This requires complex control algorithms and consumes a lot of energy to ensure that the joints move according to the pre-planned trajectory
With more functional requirements, such as maintaining a certain degree of robustness and having a natural walking gait, this structure requires more complex algorithms and precise feedback mechanisms, which undoubtedly increases a lot of energy consumption

Abstract

An energy-saving bionic tension-compression patellofemoral joint for a bipedal walking robot belongs to the technical field of mechanical bionic engineering. The invention consists of a bionic double ball component of a compression body, a bionic sliding lever component and a ligament assembly of a tension body. The invented energy-saving bionic tension-compression body knee joint utilizes a special joint geometry structure, introduces bionic slider components to reduce energy consumption, and is guided and restricted by bionic ligaments. Excessive joint movement; the invention is suitable for biped walking robots and can achieve low energy consumption , high stability, high flexibility and natural anthropomorphic gait.

Description

technical field [0001] The invention relates to the technical field of mechanical bionic engineering, in particular to an energy-saving bionic tension-compression knee joint for a biped walking robot. Background technique [0002] At present, most biped walking robots use a rigid hinge structure as the joint structure of the lower limbs, which only has a single degree of freedom in the sagittal plane accompanied by extension and flexion movements. Through motor control, this rigid hinge structure provides accurate position and torque control, and at the same time cooperates with the feedback system for accurate joint trajectory control. This requires complex control algorithms and consumes a lot of energy to ensure that the joints move according to the pre-planned trajectory. With more functional requirements, such as maintaining a certain degree of robustness and having a natural walking gait, this structure requires more complex algorithms and precise feedback mechanisms,...
