Field notes
The project combines webcam capture, MediaPipe’s 21 hand landmarks, Python/OpenCV classification, Raspberry Pi control, and a thirteen-servo hand. Its two-part learning design asks users either to sign a prompted letter for feedback or identify the letter formed by the robot. The team describes the physical platform as a tendon-driven research hand adapted from manipulation work, with a cotton glove and thumb refinements informed by a hand surgeon.
