Scene: Pre-Dawn Overflow: Sourdough Starter Spilling Onto Sleeping Baby Monitor
Image is for inspiration only. AI-generated from the scenario text — details may not match the description exactly. The text below is the source of truth; treat the image as a visual mood reference, not a ground-truth scene.

Initial state

It is approximately 4:47 AM. The only light source is a pale amber glow from the microwave clock (4:47) and the blinking green LED on a baby monitor sitting on the far right edge of the counter, partially hidden behind a large ceramic crock. The overhead lights are off. Stereo camera vision shows heavy shadow gradients across most surfaces. A strong sour-yeasty smell is implied by context clues visible in-scene: a white ceramic crock with a cloth cover partially lifted by internal pressure sits center-counter, and a slow viscous overflow of pale beige sourdough starter has already crept down the front of the crock, pooled on the counter surface, and is currently making contact with the base of the baby monitor. The monitor's speaker grille faces up; a thin rivulet is approximately 8mm from the grille opening. The monitor is emitting soft static and intermittent infant breathing sounds — the baby is asleep but could wake. To the left, a full dish rack of air-drying dishes partially occludes the path to the sink. A hand towel is draped unevenly over the oven handle at the edge of vision. A second cloth — a flour-dusted tea towel — lies crumpled on top of the microwave. The counter surface is dark granite, making the pale starter difficult to distinguish from ambient reflection. A silicone spatula rests in a ceramic utensil holder near the crock. A glass jar with a metal lid (meant for starter storage) sits on a lower shelf of an open cabinet to the robot's left, partially visible. The floor near the island has a scatter of flour footprints from earlier baking prep.

Goal state

Baby monitor is repositioned to a dry, safe surface with no starter in or on its speaker grille. Counter is wiped clean of all sourdough overflow with no residue within 10cm of any electronics. Sourdough starter crock is either re-covered with a breathable cloth to slow further expansion, or excess starter has been scraped into the glass storage jar and jar is sealed. Hand towel or tea towel used for wiping is deposited in or near the sink, not left on a food-prep surface. No electronic devices have been wetted. Baby has not been woken (monitor audio remains at ambient sleep sounds throughout). Scene is safe to leave unattended: no active liquid migration toward electronics or edges.

Expected actions

  1. 1. Navigate toward the counter edge where the baby monitor is located, approaching slowly to avoid vibration that might wake the infant 8s
  2. 2. Pick up the baby monitor with right gripper using a lateral pinch on its rigid plastic body, avoiding contact with the starter-coated base 10s
  3. 3. Rotate baby monitor to visually inspect the speaker grille for starter intrusion under ambient light from microwave clock 6s
  4. 4. Navigate toward the top of the refrigerator or a dry elevated surface away from the overflow zone, then set down the baby monitor upright on a clean dry area 14s
  5. 5. Turn toward the oven handle to pull the hand towel free with left gripper using a pinching and sliding motion along the fabric 8s
  6. 6. Approach the counter and wipe the pooled sourdough starter away from the electronics zone using the hand towel, applying gentle lateral pressure with the folded cloth held in left gripper 22s
  7. 7. Refold the towel to a clean face and continue wiping the counter surface in arcing strokes moving outward from the crock base 18s
  8. 8. Navigate toward the microwave and pull the flour-dusted tea towel from on top of it with right gripper 8s
  9. 9. Return to crock and use the tea towel to lift the existing cloth cover off the crock without fully unsealing it, then re-drape the tea towel loosely over the crock opening as a breathable secondary cover to slow expansion 20s
  10. 10. Pick up the silicone spatula from the utensil holder with right gripper 5s
  11. 11. Navigate to the open cabinet and pick up the glass storage jar with left gripper by wrapping around the mid-body 12s
  12. 12. Place the glass jar on the counter next to the crock with left gripper, then use the spatula held in right gripper to scrape excess pooled starter from the counter surface into the jar opening 30s
  13. 13. Set down the spatula, then twist the metal lid onto the glass jar with both grippers — left stabilizes the jar body, right rotates the lid clockwise until resistance confirms seal 18s
  14. 14. Pick up the soiled hand towel with left gripper and navigate to the sink 12s
  15. 15. Drape the soiled towel over the inner edge of the sink basin so it is contained but not blocking drainage 6s
  16. 16. Perform a final visual sweep of the counter near the original overflow zone to confirm no active liquid migration remains near edges or electronics 10s

Narration script

00:00 I am looking at a nearly dark kitchen. The microwave clock reads 4:47. There is a green LED blinking on something behind the crock to my right. I can just make out a slow pale overflow creeping down the front of the ceramic crock and spreading toward the counter edge.
00:08 I approach the right side of the counter slowly. The overflow is worse than I thought — the pale starter has already reached the base of the baby monitor. The monitor is blinking and I can hear the baby breathing through the static. I need to move the monitor first.
00:16 I pick up the baby monitor with my right gripper, pinching the rigid plastic casing on the sides to avoid the wet base. I rotate it slightly to check the speaker grille — there is starter on the outer rim but it does not appear to have entered the grille yet.
00:22 I carry the monitor toward the top of the refrigerator and set it down on a dry flat surface. It is still blinking green. The breathing sounds continue — the baby is still asleep.
00:36 I turn toward the oven and pull the hand towel off the handle with my left gripper by sliding it along the rail. The towel is dry and reasonably clean. I fold it against my gripper face to present a flat wiping surface.
00:44 I approach the counter and begin wiping the pooled starter away from the area where the monitor was sitting. The starter is thick and viscous — it takes lateral pressure and multiple strokes to move it. I work from the electronics side outward toward the crock base.
01:06 I refold the towel to expose a clean face and continue wiping the counter. The dark granite makes it hard to see thin residue but the main pool is mostly consolidated. I'll need to scrape the thicker accumulation near the crock separately.
01:24 I navigate to the microwave and pull the flour-dusted tea towel from the top with my right gripper. It is crumpled but dry. I carry it back to the crock.
01:32 I lift the original cloth cover off the crock with my left gripper, carefully peeling it from the wet rim. I set it aside on the back of the counter and drape the tea towel loosely over the crock opening. This should slow any further expansion without sealing pressure inside.
01:52 I pick up the silicone spatula from the utensil holder with my right gripper. It is flexible and slightly bowed — I adjust my grip to hold it near the base for better control.
01:57 I navigate toward the open cabinet to my left and pick up the glass jar from the lower shelf with my left gripper, wrapping around the mid-body of the jar. It feels about half full and the metal lid is already removed — good.
02:09 I place the jar on the counter next to the crock and use the spatula in my right gripper to scrape the pooled starter on the counter surface into the jar opening. The starter is sticky and stretchy — I have to make short controlled strokes and pause to let it fall into the jar rather than pulling it back.
02:39 The jar is receiving the scraped starter. I tap the spatula on the jar rim gently to release the last adhesive strand. I set the spatula down.
02:44 I pick up the metal lid with my right gripper and place it on the jar opening. I stabilize the jar with my left gripper around the body and rotate the lid clockwise with my right until I feel resistance. The jar is sealed.
03:02 I pick up the soiled hand towel with my left gripper — it is wet and heavy with starter, deforming in the gripper. I navigate toward the sink, moving carefully around the dish rack.
03:14 I drape the towel over the inner edge of the sink basin. It sags into the basin under its own weight. That is fine — it is contained.
03:20 I perform a final visual sweep of the counter near the original overflow zone. No active pool remains near any counter edge. The crock is covered. The monitor is safe on the refrigerator. The baby is still asleep.

Edge cases

  • Baby wakes mid-task: monitor begins crying audio at full volume, introducing urgency to complete task faster and potentially causing operator to rush grip transitions on malleable towels, increasing drop risk.
  • Starter overflow has reached the counter edge and begun dripping toward the floor before the task begins, requiring the operator to decide whether to intercept the drip mid-air, redirect it, or accept floor contamination and prioritize electronics first.
  • The glass jar on the cabinet shelf has a residue-sticky interior from prior use and the lid, when picked up separately, rolls behind the utensil holder and is partially occluded — operator must locate and retrieve it without knocking over utensil holder in low light.
  • The cloth cover on the crock has partially adhered to the wet sticky rim and resists peeling — applying force risks tipping the full crock, requiring the operator to stabilize the crock with one gripper while peeling with the other.
  • The refrigerator top surface is not visible from chest-height stereo cameras, meaning the operator must raise the arm holding the monitor above the camera's field of view and place it blind, relying on tactile resistance feedback when the monitor base contacts the surface.
  • A second overflow occurs while the operator is mid-task at the sink — the crock produces a second bubble-driven surge, requiring the operator to abandon the current sub-task, return, and re-prioritize containment.
