Bionic leg with three-dimensional force perception and spatial surface self-adaptive ability

Abstract

The invention relates to a bionic leg with three-dimensional force perception and spatial surface self-adaptive ability, which belongs to the field of application of robot technology. The bionic leg comprises a robot base (1), a hip joint, a thigh (3), a knee joint, a crus and a foot, wherein the hip joint comprises a No.I hip joint control actuator (2), a hip joint control actuator bracket (4) and a No.II hip joint control actuator (5); the knee joint comprises a knee joint control actuator (7) and a knee joint control actuator bracket (6); the crus comprises a connecting plate (8) and a three-dimensional force sensor (9); and the foot comprises a return spring (10), a globe joint and a sole (14). The bionic leg can be applied to the integrated design of a human leg part of multiple degrees of freedom microminiature leg-type robot which has three-dimensional contact force detection and the ability of a self-adaptive spatial surface adhesion sole.

AI Technical Summary

Benefits of technology

This technology allows robots that have two feet or more to sense their own forces accurately without being affected by external factors like gravity or other physical properties such as pressure from another object on top. It also includes sensors made up of tiny parts placed at specific points along its length to measure these forces effectively. These miniature devices are designed to be compact but still provide accurate measurements over large areas while maintaining good functionality even when used under different environmental conditions. Overall, this new technology enables robotics researchers to better study how they work together through interactions between humans and machines.

Problems solved by technology

This technical problem addressed in this patents relates to improving the functionality of robotic systems with six degrees of freedom: their ability to adjust themselves based upon changes in external environments such as wall dimensions, stairs, and obstacles like steps. Current designs require multiple actuators which makes these devices bulky and heavy. Additionally, current methods involve measuring linear displacement movements accurately only within certain limits, making it challenging to create an effective device capable of autonomous movement over uneven terrain.
