Failure
- yes
- onset type: obvious_mistake
- onset: 4.547244094488189 s (00:04.5)
- frame / control_step: 231 (policy_step=38, chunk_index=3)
- coarse onset: 4.0 s (refined=True)
- mode: grasp_failure
- reason: The robot attempted to grasp the yellow block but failed to establish a secure grip, leaving the block on the table while moving its empty gripper toward the wooden block. Summary: failed grasp on yellow block; moving empty gripper
- recovery: Move the arm back to the yellow block, center the end-effector, securely grasp the block, and proceed to stack it on the wooden block. Summary: re-align gripper; grasp yellow block; stack on wooden block
- prevention: Ensure the gripper is properly aligned and centered over the yellow block before closing the fingers so that the object is securely held prior to moving toward the target block. Summary: center gripper over yellow block; secure grasp before moving
- justification: At around 4.0 seconds, the robot closes its fingers around the yellow block but slips off without securing it. The end-effector lifts away empty at 5.0 seconds and moves toward the wooden block as if carrying the block.
