- Over 2,000
- Access
- Free and ungated
- Search tech
- NVIDIA USD Search
- Primary use
- Robotics and AI factory digital twins
Detailed 3D models like CAD serve as a starting point, but simulation requires extra details on how objects behave. SimReady assets include physical properties such as mass, friction, collision geometry, and sensor interactions.
What features make an asset SimReady?
SimReady Foundation specifications define the exact profiles and technical capabilities an asset requires for simulation workflows. Each profile represents a grouping of properties targeted at specific simulation tasks.
- Collision geometry and physical properties for contact and physics simulation in supported runtimes.
- Joint structures and motion limits for articulated robots and moving industrial equipment.
- Semantic labels to identify objects and generate annotated synthetic data.
- Materials and sensor attributes to assist rendering and realistic sensor simulation.
- Thermal and electrical metadata for AI factory equipment digital twins.
Which manufacturers provide SimReady assets?
Equipment manufacturers use SimReady Central to publish validated OpenUSD assets while managing their own Hugging Face datasets. This lets industrial developers test real equipment models in software before deployment.
| Contributor | Focus Area | Provided Asset Types |
|---|---|---|
| Vertiv | AI factory infrastructure | Server racks, warehouse equipment racks, cooling systems |
| Robotics OEMs (FANUC, Comau, Universal Robots, Robotiq, Franka, Standard Bots) | Industrial robotics | Articulated robot arms and grippers |
| Palatial & NVIDIA Robotics | Robotics datasets | NVIDIA Robotics 1K Dataset and complex articulated assets |
| LG Electronics | Household simulation | Refrigerators, dishwashers, and home appliances |
| ForgeCAD | Robotics perception props | Textured, articulated props for manipulation training |
How to search and use SimReady Central assets
SimReady Central lets developers and autonomous AI agents find assets and assemble them into functional OpenUSD scenes. NVIDIA USD Search provides natural-language search directly within Hugging Face.
- Search for simulation items on Hugging Face using natural language queries powered by NVIDIA USD Search.
- Filter or review asset metadata to verify that its SimReady Foundation profile matches your application needs.
- Import the OpenUSD asset into your simulation environment, such as NVIDIA Isaac, to support projects like the open-source robot Microduck.
- Compose multiple assets from different equipment suppliers into a single simulation scene.
- Configure object placements and variations to train robot behaviors or test factory floor layouts.
NVIDIA USD Search indexes simulation metadata and USD properties, allowing AI agents to discover appropriate models programmatically for physical AI tasks.
How OEMs submit assets to SimReady Central
Manufacturers can convert their internal CAD models into public simulation assets for robotics engineers. To submit assets, OEMs follow a standardized validation path.
- Prepare the equipment model in OpenUSD according to SimReady Foundation technical requirements.
- Run the SimReady Central submission skill to validate the asset against applicable profiles.
- Package the validated asset and submit it for cataloging in the SimReady Central Library on Hugging Face.
