Semantic timeline
| seconds | control_step | policy_step | phrase |
|---|---|---|---|
| 0.0–3.0 | 0–150 | 0–25 | reaching for yellow block |
| 3.0–6.0 | 151–301 | 25–50 | grasping and placing yellow block |
| 6.0–9.0 | 302–452 | 50–75 | hovering above wooden block |

Failure
- yes
- onset type: obvious_mistake
- onset: 5.199203187250996 s (00:05.2)
- frame / control_step: 261 (policy_step=43, chunk_index=3)
- coarse onset: 5.2 s (refined=False)
- mode: placement_or_insertion_failure
- reason: The robot successfully picked up the yellow block and moved it over the wooden block, but released it off-center, causing the yellow block to slide off and fall behind the wooden block. Summary: improper block placement; yellow block fell off wooden block
- recovery: Regrasp the fallen yellow block from the table, position it directly over the center of the wooden block, and place it carefully to stack it. Summary: regrasp yellow block; stack onto wooden block
- prevention: Align the yellow block directly over the center of the wooden block before releasing the gripper to ensure a stable stack. Summary: align yellow block centered; place stably on wooden block
- justification: At around 5.2 seconds (frame 00:05 to 00:06), the robot attempts to place the yellow block on the wooden block, but misaligns the placement, causing the yellow block to fall off and fail the goal predicate.
