Digital-Control Prosthetic Arm

Low-cost upper-limb prosthesis with LCD actuation control

Investigated cheaper ways to manufacture a functional prosthetic arm while keeping the necessary movements of the human arm. Replaced EMG sensing with a compact LCD control panel, reviewed actuators and electronics, and validated kinematics in CATIA V5. Built to European product-design standards with a manufacturing cost target of £500.
