A LeRobot arm on an RC car, driven by Claude Code
The maker mounted a LeRobot arm on an RC car run by a single Raspberry Pi Pico W with its own MCP server, then had Claude Code pick up a toy, throw it and spin from one plain-English instruction.

The full story
A LeRobot arm is mounted on an RC car, and the whole thing runs on a single Raspberry Pi Pico W or Pico 2 W. The board runs its own MCP server, so Claude Code can call its move, drive, pose, status and stop commands directly as tools, working out the sequence from calibration data.
In the video the only instruction typed is "pick up object on your left, throw it to your right and say bye bye". The arm picks up a soft toy, throws it, the car does a 360 and the robot goes to sleep. The firmware also ships with a CLAUDE.md and skills so Claude Code can build new projects on the board.
The firmware and hardware notes are open source in two GitHub repositories, with a Linux simulator build. The maker's next ideas include legs, cameras, a microphone and a bigger battery.
