Failure
- yes
- onset type: obvious_mistake
- onset: 5.069306930693069 s (00:05.1)
- frame / control_step: 256 (policy_step=42, chunk_index=4)
- coarse onset: 5.5 s (refined=True)
- mode: grasp_failure
- reason: The robot gripper attempted to grasp the yellow block, but closed loosely/improperly and slipped off, lifting away without holding the block. Summary: failed grasp on yellow block; gripper slipped
- recovery: Lower the gripper back over the yellow block, close firmly around it to secure a grasp, and then stack it onto the wooden block. Summary: re-align gripper; regrasp yellow block; stack on wooden block
- prevention: Center the gripper precisely over the yellow block and ensure the fingers close completely before initiating the lift. Summary: align gripper centered on yellow block; secure grasp before lifting
- justification: None
