Who it is forA desk hobbyist with a Stack-chan robot who wants the robot to face them during video calls or while they work.
The problemA fixed desk robot looks away as soon as you lean or move, so it feels disconnected from the person it is meant to engage.
The outcomeThe robot keeps facing you using face detection from your Mac camera and dual-axis servo steering, with expressive eyes shown on its screen.
What you need first
- M5Stack CoreS3 with a Stack-chan base
- A Mac for the computer-side gateway (native voice is macOS)
- Desktop Chrome or Edge for the web flasher
- The Grok Bot desktop app, signed in on the Mac
- A Wi-Fi network for the robot
Steps
- Flash the firmware with the web flasher in desktop Chrome or Edge and connect the robot to Wi-Fi.
- Clone this repository and run
cd gateway && uv sync --all-extrason your Mac. - Start the gateway as described in docs/quick-start.md and point the robot at it on the BLE settings page.
- Sit in front of the Mac camera and move slowly from side to side to check that the robot follows your face.
Prompt for your agent
In the groki-bot repo, read gateway/README.md and set up dynamic face tracking with the Mac camera for <robot-name>. Report whether the servos move when a face moves in front of the camera.
Caveat. The README says face tracking uses your Mac camera, so the camera stays on while the gateway runs and the README does not describe any privacy controls.
