Tiny Engineer

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 /anim on your LAN (integration guide)

What it feels like

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.

Build your own

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.

Roadmap

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.

How it works

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.

Clients

• Cursor - hooks → tiny-engineer-cursor → Wi-Fi
• Antigravity - lifecycle hooks → tiny-engineer-antigravity → Wi-Fi
• Claude Code - project hooks → tiny-engineer-claude-code → Wi-Fi
• Bring your own - any tool that can POST to /anim

Documentation

• Getting started - build checklist
• Shopping list - what to buy
• Integrations - Claude Code, Cursor, Antigravity, REST
• HTTP API - routes and animations
• Full docs index - wiring, CAD, flash, settings, tests

Print it, wire it, change the CAD, or hook up another agent. Issues and PRs welcome - especially new integrations. CONTRIBUTING.md · SECURITY.md · CODE_OF_CONDUCT.md
