Reachy Mini

I assembled this Reachy Mini myself, and I know it inside out. I also built a multilingual voice app for it, Reachy Mini Companion, and published it on Hugging Face.

Build it yourself

I built mine, part by part.

Reachy Mini comes as a kit you assemble yourself. Here are the seven groups of parts I put together, from the antennas down to the base. Hover a part or a name to see what it does.

  1. 1
    AntennasTwo springy antennas that give the robot its expressive character.
  2. 2
    HeadThe rounded head shell that sits on top of the neck.

Assembled by me

I put this Reachy Mini together myself, so I've handled every part of it: the head, the camera eyes, the antenna and the body.

Embodied AI in practice

It's the same robot we use at MakerWorks Lab to teach embodied AI, covering vision and interaction.

Open source

Reachy Mini is open source, so developers can write their own apps and share them with the community on Hugging Face.

Multilingual voice companion

A voice app I built for Reachy Mini on the Gemini Live API. It detects the language you speak, answers out loud in the same language and moves while it talks. Published on Hugging Face so any Reachy Mini owner can install it.
