Built on LeRobot, SO-100/101, LeKiwi and Bambot, XLeRobot is a mobile dual-arm platform for chores like tidying and fetching, with simulation support and a dual-wheel version added in Dec 2025. It's a non-profit project with kits priced low through WowRobo.

Hardware & cost: Two SO-101 arms, a mobile base, battery, head and wrist cameras, and a Raspberry Pi or laptop. From ~$660 per the README.

Difficulty: Hard.

Agent install prompt (paste into Claude Code, Cursor or Codex): "Read the XLeRobot docs at https://xlerobot.readthedocs.io, make me a BOM for the cheapest version, then set up the simulation first so I can teleop it with my keyboard before buying parts."
