MeArm-Hand-Control

A webcam watches your hands. Python (using mediapipe) tracks the landmarks of both hands in real-time, translates them into angles for the 4 servomotors of the arm, and sends them via serial port to an Arduino which applies them.

Control.py

Left hand: Thumb-index pinch → BASE rotation (pin A1)

Right hand: Hand height in the frame → arm extension: moves SHOULDER (pin A0) and ELBOW (pin 6) together in a coordinated way (hand high = arm extended forward, hand low = arm retracted) Thumb-index pinch → GRIPPER control (pin 9)

Safety

If a hand leaves the frame, its axis remains locked at the last commanded value (no sudden jumps) Spacebar → full pause of all servo motors 'q' → exit

Privacy

The face is detected using OpenCV's Haar Cascade (CPU, no conflict with the GPU/Metal engine used by MediaPipe for the hands) and automatically blurred on every frame 'f' → toggle face blur
