Scenario Lab

Initial state

You are positioned just inside the doorway of a child's bedroom. The overhead light is off. The only illumination comes from a nightlight plugged into the far baseboard — a small orange mushroom shape — and roughly forty adhesive glow-in-the-dark stars stuck to the ceiling that emit a dim blue-green wash across the upper half of the room. Stereo cameras are operating in low-light mode; the image is slightly grainy with boosted gain. A twin bed with a dinosaur-print comforter is to your left, comforter half-dragged onto the floor. On the floor between you and the bed you can make out at least three shapes: what appears to be a stuffed triceratops, a single sneaker lying on its side, and a half-visible board book whose cover is obscured under the dangling comforter edge. A small wooden nightstand is to the right of the bed; on it sits a plastic sippy cup, lid on, lying on its side. A child is asleep in the bed — small lump under the comforter, breathing audible, slow and steady. The room smells faintly of grape juice. Your goal audio cue has already played in your headset.

Goal state

The sippy cup is upright on the nightstand with lid secured. The comforter covers the child adequately (at least torso and legs covered, no large gap). The floor path from doorway to bed is clear of the stuffed animal, sneaker, and board book — all three placed on a surface other than the floor (bed foot, nightstand, or shelf) without waking the child (no vocalizations or movement detectable from the child lump for 5 seconds after task completion).

3. rotate sippy cup to upright orientation 3s
4. set down sippy cup upright on nightstand surface, releasing gently 4s
5. turn toward the floor area and scan downward to locate stuffed triceratops, sneaker, and board book under low-light conditions 6s
6. navigate around the dangling comforter edge to reach stuffed triceratops 5s
7. pick up stuffed triceratops with right gripper using wide grip around midsection 5s
8. place stuffed triceratops at the foot of the bed on top of the mattress 4s
9. pick up sneaker with left gripper, gripping around the toe box 4s
10. place sneaker on the lower shelf of the nightstand or against the wall beside it 5s

12. pick up board book with left gripper, sliding fingers under the cover 5s
13. place board book on top of the nightstand next to the sippy cup 4s
14. grasp the trailing edge of the comforter with both grippers and lift it back up onto the bed 8s
15. pull comforter gently upward until it covers the child's torso and legs, then release slowly 10s
16. retreat slowly backward toward the doorway without turning, maintaining visual on child 8s
17. pause at doorway for 5 seconds to confirm child remains still and no vocalizations occur 6s

Narration script

00:00 I am inside the doorway of a dimly lit child's bedroom. Overhead light is off. I can see glow stars on the ceiling and a small orange nightlight near the baseboard. A child is asleep in the bed to my left.

00:06 I approach the nightstand slowly to minimize motor noise. I can see the sippy cup lying on its side — purple plastic, dinosaur printed on it.

00:12 I pick up the sippy cup with my left gripper and squeeze gently along the lid seam. The lid feels secure. I rotate the cup to upright orientation.

00:20 I set down the sippy cup upright on the nightstand surface and release slowly. The cup is stable.

00:26 I turn toward the floor and scan downward. The image is grainy. I can make out the stuffed triceratops directly in front of me and the sneaker to its left. The board book is partially hidden under the comforter edge.

00:32 I navigate carefully around the trailing comforter to position myself near the stuffed triceratops.

00:37 I pick up the stuffed triceratops with my right gripper, gripping around its soft midsection. It compresses easily — soft and lightweight.

00:42 I place the stuffed triceratops at the foot of the bed on top of the mattress and release.

00:46 I pick up the sneaker with my left gripper, gripping around the toe box. It is rigid. I place it against the wall beside the nightstand.

00:55 I lift the comforter edge with my right gripper to reveal the board book underneath. The cover reads something in large letters — partially visible.

01:00 I slide my left gripper fingers under the board book cover and pick it up. It is rigid and flat.

01:05 I place the board book on top of the nightstand next to the sippy cup. The floor path looks clear.

01:09 I grasp the trailing comforter edge with both grippers and lift it back up toward the bed. The fabric is soft and slightly heavy.

01:17 I pull the comforter upward and toward the child until it covers the torso and legs. I can see the lump of the child under the cover. I release the comforter slowly.

01:27 I retreat slowly backward toward the doorway, keeping my cameras on the child. No movement, no sound from the bed.

01:32 I pause at the doorway. Five seconds. The child is still, breathing slow. Task appears complete.

Edge cases

The board book is completely invisible under the comforter on first scan; operator must infer its position from the earlier description and lift the comforter before the book can be grasped.
The sippy cup still contains liquid — when rotated to upright a small amount may slosh audibly inside, and careless placement could tip it again if the nightstand surface is slightly uneven.
The child rolls or shifts position mid-task when the comforter is being repositioned, requiring the operator to freeze all motion and wait for the child to resettle before continuing.
The sneaker has a mate somewhere in the room that becomes visible when the operator moves — operator must decide whether to retrieve the second sneaker or stay on task.
