AI Technical Summary
Technical Problem
Existing flexible fingers have limited degrees of freedom, a single mode of movement, poor rigidity, and weak load-bearing capacity, making it difficult to adapt to grasping objects of different shapes and sizes.
Method used
The rope-driven, microstructure-based flexible finger achieves multi-degree-of-freedom bending and deformation motion through the design of continuous microstructures and rope wiring. It simulates the bending motion of a human finger by combining multiple unit structures and connection points.
Benefits of technology
It improves the ability of flexible fingers to grasp objects of different shapes and sizes, has good flexibility and interactive safety, fast response speed, high transmission efficiency, and can precisely grasp fragile objects.

Abstract
本发明公开了一种基于微结构的柔性手指，包括固定件和设于固定件上的连续微结构，所述连续微结构采用弹性材料制作，由多个单元结构沿着长度方向堆叠形成；所述连续微结构的多个单元结构在拉绳驱动下能够实现柔性弯曲动作。本发明通过选择不同高度单元结构的拉结点固定拉绳调整柔性手指弯曲的形状。本发明通过选择拉结点的数量来调整柔性手指的运动自由度，形成多自由度柔性手指，四边形结构的至少一个边设置有拉结点。具有可编程的自由度设计，大大提高了柔性手指对于不同形状和尺寸物体的抓取能力。
