We gave a Reachy Mini a real-time voice brain

We attended an event the other day and found this little guy lying on our desk, a Reachy Mini from Hugging Face. It belongs to the daughter of the event organizer. We got curious about how it worked, and an hour later we'd given it a brain. The model basically becomes Reachy. It hears through its mic, sees through its camera, talks through its speaker, and calls motion tools to physically react while it talks. Repo: [https://github.com/opper-ai/reachy-voice-realtime](https://github.com/opper-ai/reachy-voice-realtime) Key things: * Web UI to watch the camera feed, transcript, and tool calls live. * 19 motion and perception tools the model calls mid-conversation (emotes, head/antenna/body movement, camera, sound direction). * Mimics you, wave and it waves back, nod and it nods, tilt your head and it tilts. * Runs on GPT Realtime 2, routed through Opper so the model is a one-line swap. * The realtime client and tool layer are separate, so you can also wire it straight to a provider or a local/OS realtime model. Setup's in the README (Python 3.12+), MIT licensed. We handed it back to his daugther so now she can finally talk to her robot.
