RT-1

Google Robotics

Robotics Transformer policy trained on large-scale real-world robot demonstrations for language-conditioned manipulation.

Real-world task success

Primary blocker

A useful baseline for understanding why policy learning needs action/state alignment, not only video.

Training data requirements

Useful
76confidence 50

Required signal categories are declared; exact tensor and action interfaces still need verification.

Evaluation evidence

Useful

Evaluation focus is declared, but metrics are not independently verified.

Deployment readiness

Unknown
confidence 10

Hardware, latency, dependencies, and runtime loading are not yet verified.

Artifact facts and provenance
