Scanned Objects MuJoCo Models

This repository contains MuJoCo MJCF models for all 1030 household objects in Google's Scanned Objects Dataset. The XML files were automatically generated using obj2mjcf. A sample of the models is shown below:

Structure

In each object directory, you'll find the following:

model.obj
model_collision_*.obj  # 32 collision submeshes.
texture.png
model.xml

The model definition lives in model.xml. To visualize it, you can drag-and-drop it in the simulate binary. You can examine the visual and collision meshes by cycling between groups 2 and 3. The collision mesh is a convex approximation that has been generated with V-HACD.

If there are any problems loading a particular model in MuJoCo, please raise an issue on the GitHub repository.
