X Square Robot open sources its robot-free data collection framework

XRZero-G0, released by X Square Robot under an MIT license, is a hardware and software framework plus the G0-Dataset for collecting human demonstrations to train robot policies; it uses head and wrist cameras, a wearable VR interface, and automated quality-control (geometric consistency, inverse kinematics checks, and physical playback), and the G0-Dataset contains over 2,000 hours across 3,000 manipulation tasks—enabling faster data collection, a reported ~85% validated data yield, a 10:1 human-to-robot data ratio, and demonstrated cross-embodiment and zero-shot transfer.
