Abstract

Provided is a bionic tension buffering foot-ankle system. The system includes two levels of tension structures, not only can the first tension structure ensure the integral structure to achieve a buffering effect, but also since the self-balance and self-stability of the tension structure ensure the stable balance when the integral foot-ankle system is in contact with the ground, functional characters of rigid supporting and flexible buffering can be achieved. The second level tension structure can ensure the structural stability and absorb impact force through deformation of tension springs at the same time, and the tension structure with flexibility and self-balance stability further strengthens the buffering functional character of the bionic tension foot-ankle system.

Description

technical field [0001] The invention relates to the technical field of mechanical bionic engineering, in particular to a bionic tension buffer foot-ankle system applied to a quadruped robot. Background technique [0002] With the rapid development of bionic technology, bionic walking robots are widely used in many fields of various industries, such as military reconnaissance, material delivery, field investigation, emergency rescue and disaster relief, etc., replacing people in dangerous work, greatly increasing the work of people Safety and reduced work intensity. The quadruped walking robot not only has the remarkable characteristics of strong carrying capacity, good stability, and simple structure, but it can also walk on structured roads and complex terrain in a static walking manner, and can realize high-speed movement in a dynamic walking manner. extensive attention of domestic researchers. [0003] At present, the feet of quadruped robots are mostly arc-shaped or sp...
