Overview

The January 2024 Stanford project that went viral for cooking shrimp and taking elevators after learning from ~50 human demonstrations. It made low-cost bimanual mobile teleoperation and imitation learning the template for a wave of home-robot startups. Trossen sells a commercial version, and many labs build their own from the open design.
