Dataset Viewer
The dataset viewer is not available for this split.
Cannot extract the features (columns) for the split 'validation' of the config 'default' of the dataset.

Pilot test
Two collections of simulated robot manipulation recordings:
| Collection | Contents |
|---|---|
| Object Understanding | Existing object measurement and selection collection. |
| Spatial Transformation | 100 successful episodes; 100 HDF5 recordings and 400 videos. |
Spatial Transformation includes four RGB/depth views at 256 x 256, 20 Hz.
See Object Understanding notes and Spatial Transformation documentation for collection details and reading instructions.
Spatial Transformation passed automated integrity and physical checks. Full trajectory observability review remains pending; original unverified annotations are retained. Historical files retain original runtime paths as provenance. The Spatial Transformation recording index uses portable relative paths.
