How is the door with round knob modeled?

A knob needs a twisting grasp, which is harder than a lever. The knob turns on its own joint with a return spring and drives the latch, and the door swings on its hinge.

Which parts of the door with round knob move?

Door leaf
Revolute hinge
Knob
Revolute with return spring

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.

  • Articulated. Rigid links joined by revolute, prismatic or helical joints, with limits, damping and springs where the real object has them.

Where is it used?

  • Opening doors with a knob
  • Navigation

Industries: Household, Hospitality

Questions

Which simulators does the door with round knob 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.
