What it does

Code Generator: Pick a robot and an action (beep, probe, drive, wave). Get runnable code in Pybricks, LEGO Stock Python, ev3dev, NXT-Python, or NQC depending on the generation. Download as .lms, .py, or .nqc.

Builder: Step through one safe test at a time. Generate code, run it, record what happened, get the next suggestion.

Connect: Bluetooth (BLE) or USB Web Serial. Works with stock LEGO firmware via LWP3 and with Pybricks for a full Python REPL.

Voice control: Load an Edge Impulse keyword-spotting model and trigger robot actions by voice in the browser.

Built with Kotlin and Jetpack Compose, with BLE and USB transport, session history, and voice keyword spotting. F-Droid submission pending.

Pybricks Firmware

If you choose a Pybricks code target, install or restore firmware through Pybricks:

• Pybricks Code: https://code.pybricks.com/
• Install Pybricks firmware: https://pybricks.com/learn/getting-started/install-pybricks/
• Pybricks documentation: https://docs.pybricks.com/

This project generates compatible Python and handoff steps; it does not bundle Pybricks firmware.

MCP server

For use with AI agents (Claude Desktop, VS Code Copilot, Cursor):

npx -y mindstorms-robot-creator

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "mindstorms-robot-creator": {
      "command": "npx",
      "args": ["-y", "mindstorms-robot-creator"]
    }
  }
}

Or in .vscode/mcp.json:

{
  "servers": {
    "mindstorms-robot-creator": {
      "type": "stdio",
      "command": "node",
      "args": ["${workspaceFolder}/mcp-server.js"]
    }
  }
}
