 A local web-based control interface for the Jibo social robot. Re-Commander connects directly to Jibo's on-device ROM (Robot Operating Module) over your local network, giving you a browser UI to control head movement, speech, listening, display, camera, and an LLM voice-AI loop — all without any cloud dependency.

 Jibo must be placed into `int-developer` mode before the server can open a WebSocket session with it. In this mode the robot exposes its ROM WebSocket API on port 8160 and its local ASR service on port 8088.
 
-To enable it:
-
-1. On your phone, open the Jibo app and connect to your robot.
-2. Navigate to **Settings → Developer Options** and enable **Developer Mode**.
-3. On the robot itself (or via the app), switch the operating mode to **`int-developer`**.
-4. The robot will reboot. Once it is back up and on Wi-Fi, its ROM API will be accessible at `<robot-ip>:8160`.
-
-If you are unsure whether your robot is in the right mode, try `curl http://<robot-ip>:8160/request` — if you get a JSON response (even an error), the port is open.
