Editorial analysis
The records describe different training resources
The table combines teleoperation, human-motion data, simulated environments and embodied datasets. An hour measures duration. A trajectory measures an episode. A fleet count describes collection hardware. None can be converted to another without additional information.
Subsets can overlap larger collections
The four Figure logistics training subsets belong to one scaling study. They should not be added as independent datasets without establishing that their episodes are disjoint. Likewise, a robot count and task count can describe the same collection rather than extra training volume.
Volume leaves quality unresolved
For a training decision, inspect task coverage, recording quality, action labels and compatibility with the target robot. A larger number of trajectories can still contain repetitive or unsuitable examples. This page organizes the reported resources without assigning a universal data-quality score.
