AI Technical Summary
In existing robot shock absorption structures, relying on springs for shock absorption is ineffective and cannot effectively alleviate the vibration of the robot on uneven ground.
It adopts a biomimetic elastic buffer structure, including components such as sliders, grooves, sliding columns, magnetic plates, elastic bands and guide rollers, to simulate the buffering characteristics of human ligaments. Through the combination of magnetic plate repulsion force, elastic band and spring, the elastic recovery force is precisely controlled to improve the buffering effect.
It significantly improves the robot's shock absorption effect, achieving flexible release and absorption of impact force, ensuring the buffering effect while improving the accuracy and efficiency of shock absorption.
