Spilled Movie Night Snacks Before the Guests Arrive
Initial state
You are facing into a dimly lit living room at roughly 6:45 PM — warm overhead light is off, only a floor lamp in the far-left corner is on, casting long shadows across the carpet. A large sectional sofa dominates the center-right of view; a fleece blanket is half-draped off the left cushion and pooling on the floor. On the coffee table — a dark-stained wooden rectangle about 70 cm high — a family-size bag of tortilla chips has tipped over, and roughly 40–60 chips are scattered across the table surface and have cascaded onto the beige carpet below. A plastic salsa jar (lid still on, mostly full) is on its side next to the bag, resting against a TV remote. A half-drunk glass of lemonade sits near the table's far edge, visibly close to tipping. In the background, through a doorway at the back of the room, the sound of a microwave beeping is audible and a child can be heard humming — neither will enter the scene. The far right shows a tall bookshelf with its lowest shelf partially blocked by a backpack on the floor. A recycling bin is just barely visible around the corner to your left. Ambient: faint traffic noise, the hum of a nearby AC unit. Chips under the sofa are partially visible but mostly occluded by the sofa skirt.
Goal state
All visible tortilla chips are cleared from carpet and table surface. Chips are deposited into a container or bag suitable for disposal (the chip bag or recycling bin). The salsa jar is upright and stable on the table. The lemonade glass is moved to a safe non-tipping position. The blanket is folded or at minimum no longer pooling on the floor as a slip hazard. The coffee table surface is clear enough that coasters and remotes can sit flat. Under-sofa chips that cannot be reached without moving furniture are acknowledged as out-of-scope; visible ones near sofa edge are retrieved. No items are knocked over during the process.

Expected actions
- 1. Approach coffee table from the front, slowing to assess full scatter pattern of chips on table and carpet 8s
- 2. Pick up lemonade glass with right gripper and slide it toward the center of the table away from the edge, then release 12s
- 3. Pick up salsa jar with left gripper, rotate it upright, and place it next to the far edge of the table in a stable position 14s
- 4. Pick up chip bag with right gripper, open the bag mouth wide by pulling the top edges apart with both grippers, and hold it open as a collection vessel 18s
- 5. Lower left gripper to table surface, slide chips into chip bag in two to three sweeping pushes across the table 30s
- 6. Set chip bag down on table temporarily with open end up, transition to carpet chip retrieval 8s
- 7. Navigate around left side of coffee table to access carpet chips closest to table base, pick up clusters of chips with left gripper by scooping two to four at a time 40s
- 8. Transfer carpet chip clusters into open chip bag, repeating until table-adjacent carpet is cleared 35s
- 9. Turn toward sofa, approach the sofa skirt edge, lower camera angle by crouching chassis if possible to identify chips near sofa edge on carpet 12s
- 10. Pick up individually visible chips at sofa edge — those within gripper reach — and deposit them into chip bag 30s
- 11. Navigate around sofa left flank to access chips that rolled behind the blanket pool on the floor 15s
- 12. Pick up the pooled fleece blanket with both grippers, fold it in half once lengthwise, then fold again to create a rough rectangle 35s
- 13. Place folded blanket on left sofa cushion on top of the seating surface 10s
- 14. Retrieve any chips that were under or adjacent to the blanket, deposit them into chip bag 20s
- 15. Twist chip bag closed at the top by rotating both grippers in opposite directions, then carry bag to recycling bin around the corner and set it inside 25s
- 16. Navigate back to coffee table, do a final left-to-right visual sweep of table surface and surrounding carpet to confirm clearance 10s
- 17. Pick up TV remote that may have shifted during salsa jar handling and place it parallel to table edge in a natural position 8s
Narration script
Edge cases
- The lemonade glass is knocked over during chip sweeping because the gripper catches it on the backstroke — operator must immediately pause chip task, pick up glass, assess whether spill occurred on carpet or table, and if so add spot-wiping to the task queue before continuing.
- The salsa jar lid is actually slightly loose from a previous use and tilts when uprighted, making the jar wobble and threatening to tip — operator must use both grippers to stabilize and test before releasing.
- Several chips have slid under the sofa skirt beyond gripper reach. The operator must decide whether to attempt repositioning the sofa slightly (high effort, risk of scratching floor) or to mark those chips as out-of-scope and accept partial completion — a deliberate no-perfect-answer tradeoff that tests planning judgment.
- The blanket, when lifted, reveals a children's small stuffed animal that had been lost under it — not part of the original task but now visible on the floor as a potential tripping hazard; operator must decide whether to pick it up and place it somewhere appropriate.
- The recycling bin around the corner turns out to already be full and overflowing, so setting the chip bag inside without it falling requires careful balancing or choosing the alternate disposal option of placing the bag on the kitchen counter for later.
