Calibra is an open-source toolkit designed to audit robot datasets and identify quality issues before training. It provides tools for building quality-aware coresets and estimating training outcomes.

  • Robot Dataset Health Check: an interactive Space for auditing LeRobot datasets.
  • A benchmark of 30 public LeRobot datasets with health scores and diagnostics.
  • Quality-aware coreset selection and training outcome prediction capabilities.
  • Python API and CLI for integration.

The toolkit aims to help users understand dataset quality early in the workflow.
