# Manipulation Objects Kitchen MJCF
We provide a collection of digital 3D mjcf assets intended for use in a simulated kitchen environment.
The assets are broadly divided into 2 categories: fixtures and objects. The fixture assets are comprised of interactable kitchen appliances such as stoves, microwaves, and ovens. The object assets consist of common kitchen objects such as saucepans and glass cups.

### Directory Structure
The object folder of the repository is organized by object category. Each object category is stored as a zip. Within each zip, each category contains multiple unique model variations. Each individual model folder is self-contained with its mjcf definition, visual meshes, textures, and decomposed collision meshes.

### Directory Structure
The fixture subfolder is organized similarly to the object subfolder. Each fixture category is stored as a zip, and, within the zip, there are variations of the fixture category and self-contained assets.
