Give your AI coding agent a body.
Watch the demo · Build your own · Community builds · How it works
- Looks around while the agent reads
- Types while it writes code
- Looks up while it thinks
- Rings the bell when the task is done
Works with
- Ready integrations: Claude Code · Cursor · Antigravity
- Any agent with HTTP: Codex, Windsurf, custom scripts,
POST /animon your LAN (integration guide)
| Your agent… | Tiny Engineer… |
|---|---|
| Reads files | Looks around |
| Edits code | Types |
| Thinks / waits | Looks up |
| Finishes a task | Rings the bell |
Open-source desk robot: 3D-printable body, Wi-Fi, and a small REST API so your tools can drive the poses.
| Parts (electronics + 5× SG90 Servos) | About $50–70 shopping list |
| Also budget for | 3D printer + filament, or order prints; M2 screws; 5 V / ≥2 A USB supply |
| Tools | Soldering required (modules and harness wires) |
| Difficulty | Medium - fair first hardware project for a software engineer, not a one-LED kit. Optional primer: From Code to Circuits |
Print → Wire → Flash → Assemble → Connect - step-by-step: Getting started.

What we are building toward:
- Integrated PCB - less wiring, faster builds
- More agent integrations - one-command hooks for more IDEs and CLIs
- Simplified build process - easier assembly and setup for quicker builds
- New characters / bodies - alternate shells and mods
- Multi-agent desk - more than one tiny teammate
Star Tiny Engineer to follow the build.
Your agent (or a hook script) sends poses over HTTP. The ESP32-C3 on the robot runs the REST API, animations, and audio, then drives five servos, an OLED face, and a speaker.
