Reactor

A world that can be seen, heard, and sensed.

Someone calls from across the room. A hand moves beside the camera. The surface under a device shifts. Each moment carries a cue about what is happening nearby.

We want to build machines that can notice those cues and respond in ways people understand. Reactor explores that idea through two devices: an expressive robot and a compact sensing hub. They share a Radxa ZERO 3W host and four-microphone audio, with different bodies and ways to interact.

Meet the projects

Each project has its own guide, animated previews, STL parts, one final assembled Blender model, firmware and build instructions. The GIFs above show the devices rotating, separating into modules and coming back together, with English explanations.

What you can explore

These are evolving hardware projects. Sound-source localization, sensor fusion and autonomous responses are development goals. Each project guide distinguishes the supplied files and recorded checks from work that still needs assembled hardware testing.

Start exploring

1. Choose a project above. Its README introduces the device and points to the relevant files.

2. Retrieve the large models with Git LFS. Run these commands inside your checkout:

   git lfs install --local
   git lfs pull

3. Open an editable assembly. Start with Donald Microduck or Mickey Hub, then follow the project's build guide.

The repository includes firmware and application sources, native electronics, manufacturing files, STL exports, one final assembled Blender file per project, GIF previews and captions. Component GLBs, STEP references, intermediate design files, separate animation scenes and full MP4 renders stay in the local memory_backups/ directory, alongside render caches and conversation history. They are excluded from commits and source archives.

Contribute

Work on mechanical fit, audio processing, perception, firmware, host applications and interaction design is welcome. Identify the affected project, explain the change and include the checks needed to reproduce your result.

Licenses

Mickey Hub's limited commercial permission covers up to and including 100 devices or one-device kits sold by the same individual or legal entity each calendar year. Before selling the 101st unit, obtain separate written authorization from the Reactor maintainers. The complete grant defines the counting rules and third-party exclusions.

Original shared documentation and graphics use CC BY-NC 4.0. Third-party material retains its own terms. LICENSING.md defines the project scopes, commercial authorization and model exceptions; THIRD_PARTY.md records upstream sources.
