## Dataset Description
|
| 30 |
+
|
| 31 |
+
10fps downsampled LeRobot v3 dataset for the UR7e stack-block task. It is derived from CoRL2026-CSI/UR7e-CaP-Stack_Block-100epi by keeping source frames 0, 3, 6, ... in each clean forward-success episode. Numeric observations and absolute 7D UR7e actions are copied from retained source frames without interpolation.
