Scenario Lab

Initial state

You are positioned at the far end of a narrow hallway, roughly 4 meters from the front door. Morning light — pale and grey — leaks through the frosted sidelights flanking the door, suggesting overcast weather outside. The overhead light is off; the only illumination is that diffuse cold daylight. A dripping wet umbrella is lying diagonally across the doormat, handle poking toward the left baseboard, tip touching the right-side shoe rack. A puddle roughly the size of a dinner plate has formed under the umbrella's midsection. Against the right wall you can partially see a cluttered shoe rack — two sneakers have toppled off and lie on the floor — and a wall hook at chest height holds a dry jacket. On the left wall, about a meter from the door, a tall wicker basket meant for umbrellas sits empty. The basket is partially occluded by a backpack that has been dropped directly in front of it. Somewhere further back in the house, fast footsteps and a child's voice — 'Has anyone seen my library book?!' — create ambient urgency. A damp smell and the sound of rain on the exterior of the door are faintly present.

Goal state

The wet umbrella is standing upright inside the wicker basket (or leaning securely against the wall inside it), no longer in contact with the doormat or floor in the path of the door's swing arc. The puddle on the floor does not need to be fully dry, but the umbrella should not be actively dripping onto a walking surface in the main traffic path. The doorway is fully clearable by a person walking through without stepping over anything. The backpack may remain in place if it does not block the basket or the door path. Fallen sneakers are considered out of scope but may be righted if encountered incidentally.

Objects involved

Name	Descriptor	Role
wet umbrella	full-length, dark navy, fabric canopy partially collapsed, shaft damp	target
wicker umbrella basket	tall cylindrical, natural tan wicker, open top, floor-standing	tool
doormat	rectangular, dark rubber-backed, fibrous surface, wet in center	obstacle
backpack	medium-sized, blue nylon, straps loose, sitting upright on floor	obstacle
puddle	irregular, dinner-plate-sized, clear water on tile floor	obstacle
shoe rack	freestanding, dark metal, three tiers, partially loaded with footwear	distractor
fallen sneakers	white canvas, child-sized, lying on their sides on the floor	distractor
wall hook jacket	adult dry jacket, olive green, hanging on single hook at chest height	distractor

Expected actions

1. approach the wet umbrella from the far end of the hallway, navigating around the dropped backpack 8s
2. identify the umbrella's handle end and tip orientation to determine optimal grip point 3s
3. pick up the umbrella by the handle using the left gripper, lifting vertically to avoid dragging the wet canopy through the puddle 6s
4. rotate the umbrella to a near-vertical orientation, tip pointing downward, to match the intended storage posture 4s
5. turn toward the wicker basket on the left wall 3s
6. navigate around the backpack to gain a direct approach angle to the basket opening 5s
7. lower the umbrella tip-first into the wicker basket, releasing grip once the umbrella is balanced upright inside 6s
8. verify the umbrella is stable and not tipping before retreating 4s

Narration script

00:00 I can see a wet umbrella lying diagonally across the doormat, blocking the door path. There is a puddle forming under it. The wicker umbrella basket on the left wall is the obvious target but a backpack is sitting in front of it.

00:08 I am approaching the umbrella, navigating around the dropped backpack to reach the doormat area. The umbrella tip is against the shoe rack on the right side.

00:16 I am assessing the umbrella — handle end is toward the left baseboard, roughly at gripper height if I extend the left arm downward. The canopy is wet and the fabric is bunched loosely around the shaft.

00:19 I am picking up the umbrella by the handle with the left gripper, lifting slowly and vertically so the wet canopy does not drag across the floor or flick water onto the baseboard.

00:25 I have the umbrella in a near-vertical orientation, tip pointing down. It is stable in the gripper. I am turning toward the wicker basket on the left wall.

00:28 The backpack is directly in front of the basket. I need to navigate slightly to the left to get a clear angle on the basket opening without the backpack obstructing my approach.

00:33 I am now in front of the basket with a clear line to the opening. I am lowering the umbrella tip-first into the basket slowly, keeping it vertical so it does not catch on the wicker rim.

00:39 The umbrella tip has seated in the base of the basket. I am releasing the gripper gently and confirming the umbrella is balanced upright and not tipping toward the wall or the backpack.

00:45 The umbrella is standing upright inside the basket. The doormat and door swing arc are now clear. The puddle remains on the floor but is outside the main walking path. Task is complete.

Edge cases

The umbrella's canopy is not fully collapsed — fabric is billowing slightly open — making the object wider than expected and causing it to catch on the wicker rim during insertion; operator must partially compress the canopy against the shaft using the second gripper before lowering into the basket.
The wicker basket tips over when the umbrella is placed inside it because the basket is lightweight and the umbrella handle is heavier than the canopy end, shifting the center of mass; operator must reposition the basket against the wall before re-inserting the umbrella.
A child runs into the hallway from a back room mid-task and kicks the backpack further in front of the basket, fully blocking it; the operator must pause movement and re-route to approach the basket from a different angle once the child has passed.
