Overview

This entry covers tooling around the LeRobot dataset format—conversion, visualization, and recording utilities that keep teleop logs and training data aligned. In practice you will mostly live inside the main LeRobot repo and Hub dataset cards, but treating “format tools” as a first-class concern prevents silent train/serve skew.

Who it is for

Anyone standardizing on LeRobotDataset for multi-robot data.

Key highlights

  • Format conversion
  • Episode visualization
  • Recording alignment helpers

When to use

  • Migrating legacy demos into LeRobot format

When not to use

  • You are not using LeRobot data schema at all

Getting started

  1. 1Read LeRobot dataset docs
  2. 2Convert one episode and visualize
  3. 3Validate action dims and timestamps

How it compares

Caveats & pitfalls

  • Schema versions must match training code.
