Drag to orbit, scroll or pinch to zoom. Solid: what ATIANA's first five-servo hand can reach. Gold wireframe: the intended human pose (wrist, thumb opposition and finger spread have no actuator yet).

Camera imitation

camera off

Privacy: the camera starts only when you press Start camera. Video is processed by MediaPipe inside this browser tab; no footage or hand data is uploaded, recorded or stored, and this page makes no network requests other than loading its own files. Press Stop camera (or leave the tab) to release the camera.

Put a hand in Camera mode to imitate you. When your hand leaves the view or tracking becomes unreliable, the robot hand holds its pose and resumes after half a second of stable tracking. Works best in good light with the whole hand visible.

Hand & control mode

One controller owns each hand. Switching mode decelerates the hand and holds it; the new controller continues from there (no jumps). Stop and emergency stop work in every mode.

“Simulation only” gestures need a wrist actuator or thumb opposition the five-servo hand does not have; they play on the anatomical (ghost) hand in simulation and are refused on hardware.

Servo targets

    Cyan: commanded pulse. Green: simulated servo response. Hobby servos report no position or force, so on hardware only the command is known.
