Deformable fitted sheet

A deformable fitted sheet with elastic corners, modeled as cloth with an elastic edge for bed making robots.

Also called fitted bed sheet or bottom sheet.

ClothElastic rod

Delivered as USD for NVIDIA Isaac Sim

How is the deformable fitted sheet modeled?

The fitted sheet is the hard one: four sewn corner pockets and an elastic band that gathers the edge. We model the sheet as cloth and the elastic as a stretchy rod along the hem, attached to the cloth, so the edge gathers when relaxed and stretches over a mattress corner.

Pocket depth is set to the mattress it fits, from standard to deep.

Which parts of the deformable fitted sheet deform?

Sheet: Thin cloth with sewn corner pockets
Elastic edge: Stretchy band that gathers the hem

What ships in the USD?

One USD file per variant, with the render mesh, the simulation geometry and a physics material bound to it. Every value is set and named, so you can open it in NVIDIA Isaac Sim and run your task, or read the numbers into your own solver from the material JSON.

Cloth. A triangle surface with stretch, shear and bending stiffness and a thickness. Used for towels, sheets and garments.
Elastic rod. A centerline curve with a radius, and stiffness in bending, twisting and stretching. Used for cables, wires, hoses and ropes.

Where is it used?

Fitting a sheet over a mattress
Folding a fitted sheet
Hotel housekeeping

Industries: Hospitality, Household

Questions

Which simulators does the deformable fitted sheet open in?

It ships as USD for NVIDIA Isaac Sim and Newton. We also deliver MJCF for MuJoCo and Genesis, a GLB mesh, and a JSON file with every material value.

Can it be matched to our real object?

Yes. Send us a sample, a drawing or a few photos and we set size, stiffness and friction to match your part.

How do we get it?

Choose your simulator, format and variant, then tell us where to send it. We prepare the files and email them to you.
