π*0.6: four hours of robotic box assembling

Summary
This video is an unedited, extended autonomous demonstration presented by Physical Intelligence (π), showcasing their robotic manipulation policy (identified in the title as π*0.6). Over an unbroken span of nearly four hours, a bimanual robotic arm system continuously and autonomously picks up flat cardboard sheets, folds and forms them into assembled boxes, and places them into storage bins.

What is shown

• Autonomous Bimanual Box Assembly: Two robotic arms mounted on a workshop table manipulate flat cardboard cutouts, coordinating both end-effectors to fold flaps, crease edges, and square the boxes into finished form [00:30–02:30].
• Continuous Multi-Hour Operation: The robotic system repeats the box-folding workflow continuously at 1x real-time speed across the multi-hour video without policy failure [00:00–230:10].
• Human-in-the-Loop Environment Maintenance: A human technician periodically enters the frame to remove stacks of assembled boxes from the bin and restock flattened cardboard sheets while the robot continues operating [26:15–26:50, 50:20–50:30, 77:35–77:45, 119:10–119:25, 133:35–134:10, 154:10–154:20].

Claims & numbers

• Runtime: Approximately four hours of continuous autonomous box assembling at real-time (1x) playback speed (indicated by on-screen overlay "autonomous, 1x" and the video title).
• Autonomous Execution: The folding policy operates fully autonomously without teleoperation during assembly cycles (indicated by on-screen overlay).

Notable quotes

• None (the video has no spoken dialogue, narration, or voiceover).

Assessment
This is a real, unedited long-duration endurance demo of physical AI manipulation from Physical Intelligence. The entire multi-hour run is shown in continuous real-time without cuts or speed-ups, demonstrating robust generalization and long-horizon bimanual dexterous manipulation.
