This project has designed a partially underactuated bionic dexterous hand that achieves joint flexion with multiple degrees of freedom through a wire-driven mechanism and incorporates pressure sensors at the fingertips along with pneumatic corrugated tubes for flexible gripping. The bionic hand serves multiple purposes: firstly, it can be controlled by receiving electromyographic signals from the human body to assist amputees in performing daily activities through the contraction and relaxation of the hand; secondly, it can be manipulated to execute specific movements by using computer vision to record real-time hand videos, extract skeletal points, and calculate finger joint angles with the MediaPipe machine learning model. Our dexterous hand boasts a low production cost, diverse applications, and holds a broad range of application prospects.
