Designed and fabricated a tendon-driven robotic finger prototype with 3 degrees of freedom, Arduino-based servo control, and MyoWare EMG input for prosthetic-hand development.
The goal was to create a low-cost robotic finger system that could convert forearm muscle activation into repeatable finger motion while fitting within a compact prosthetic-hand architecture.
Individual project. Responsible for mechanical design, CAD, 3D printing, tendon routing, servo integration, wiring, EMG testing, and Arduino control logic.
The prototype uses a tendon-driven finger structure actuated by servos and controlled through Arduino logic. EMG input from the forearm is filtered and thresholded to trigger finger motion.
Testing focused on EMG signal consistency, servo response, tendon routing, and repeatable finger movement.
Future revisions would improve tendon routing, reduce friction, add position feedback, and test repeatability across repeated grip cycles.
