Precision manipulation success

Main blocker

Hardware, latency, dependencies, and checkpoint loading are not pipeline-tested.

Next check

Run a checkpoint loading smoke test before marking the model pipeline-tested.

OpenBot notes

  • A practical baseline for dataset readiness because it needs clean action supervision.
  • Useful when a dataset is too narrow for generalist policies but strong enough for task-specific imitation.
