| seconds | control_step | policy_step | phrase |
|---|---|---|---|
| 0.0–3.0 | 0–150 | 0–25 | lowering arm toward yellow block |
| 3.0–6.0 | 151–301 | 25–50 | grasping and lifting yellow block |
| 6.0–9.0 | 302–452 | 50–75 | placing block on wooden block |
| 9.0–12.0 | 453–603 | 75–100 | retracting gripper and hovering |

Failure
- yes
- onset type: obvious_mistake
- onset: 5.059760956175299 s (00:05.1)
- frame / control_step: 254 (policy_step=42, chunk_index=2)
- coarse onset: 8.0 s (refined=True)
- mode: placement_or_insertion_failure
- reason: The robot attempted to stack the yellow block on the wooden block, but misaligned the block upon release, causing it to slide off onto the table surface. Summary: misaligned block placement; block sliding off target
- recovery: Re-grasp the fallen yellow block from the table surface, align it directly over the center of the wooden block, and release it gently. Summary: re-grasp yellow block; place on wooden block
- prevention: Ensure the yellow block is centered and flat on top of the wooden block before releasing the gripper to achieve a stable stack. Summary: center yellow block; release stably
- justification: None
