Due to diversity in amputation possibilities, this thesis focuses on the specific case of ring finger amputation with some amount of stomp remaining. The goal is to design a robotic finger as a prosthetic, which its flexion and extension (position control) are instructed from an armband. The armband is equipped with 8 force sensors to detect volume variations in patient’s forearm. Its embedded microcontroller processes signals taken from these sensors, and using machine learning techniques (K-Nearest Regressor), decides on a specific angle for the finger. This angle value updates constantly, and using a flex sensor and a DC motor in finger, the desired flexion/extension is performed....
