Semantic timeline
| seconds | control_step | policy_step | phrase |
|---|---|---|---|
| 0.0–3.0 | 0–150 | 0–25 | approaching yellow block |
| 3.0–6.0 | 151–301 | 25–50 | grasping and moving yellow block |
| 6.0–9.0 | 302–452 | 50–75 | positioning block on wooden block |
| 9.0–12.0 | 453–603 | 75–100 | holding yellow block on target |
| 12.0–15.0 | 604–754 | 100–125 | remaining stationary over block |
| 15.0–18.0 | 755–905 | 125–150 | idle with gripper closed |
| 18.0–20.5 | 906–1028 | 151–171 | idle with gripper closed |
Failure
- yes
- onset type: operator_intervention
- onset: 6.242544731610338 s (00:06.2)
- frame / control_step: 314 (policy_step=52, chunk_index=2)
- coarse onset: 7.0 s (refined=True)
- mode: stuck_or_no_progress
- reason: After placing the yellow block on top of the wooden block, the robot failed to open its gripper to release the object and remained stuck in position until time expired. Summary: stuck on target; failure to release gripper
- recovery: Open the gripper to release the yellow block onto the wooden block, then raise the arm away from the stack. Summary: open gripper; retract arm
- prevention: Command the gripper to open immediately once stable contact with the wooden block is made, then retract the arm. Summary: release block on contact; retract arm
- justification: The robot successfully picked up the yellow block and aligned it on top of the wooden block by around 00:06. However, at around 00:07, it stopped making progress and remained frozen with its gripper holding the block until the end of the episode.
