A field guide to 5 humanoid and bimanual manipulation datasets in LeRobot v3.0 — with the exact state/action dimensionality, fields, and research behind each one, and why "humanoid dataset" hides a 7x spread in how these robots actually represent themselves.

Two robots doing near-identical tasks—reach into clutter, pick something up, place it somewhere—can record their own state as a 29-dimensional vector or a 216-dimensional one, depending entirely on how many joints, cameras, and collection-process signals the platform records. Neither number is wrong.…
