NVIDIA puts 2,000+ sim-ready robot assets on Hugging Face
Comau, FANUC, Franka, Robotiq, Standard Bots, Universal Robots and KUKA are all in the library, free and ungated.
NVIDIA Robotics has published more than 2,000 simulation-ready 3D assets on Hugging Face, free and ungated. Seven robot makers are in there with models of their own hardware. Comau, FANUC, Franka Robotics, Robotiq, Standard Bots, Universal Robots and KUKA.
That list is the news. Lukas Ziegler, who flagged the drop, points out that these vendors have historically kept CAD close and shipped simulation inside their own software, things like RobotStudio, RoboGuide and KUKA.Sim. Publishing an open asset is a concession that the scene now gets assembled somewhere else, in another company's simulator, and increasingly by another company's agent.
Why a CAD file is not enough
Ziegler's substantive point is the one worth keeping. A CAD model is not a simulation asset. To actually simulate, the file needs collision geometry, mass and inertia, friction, joint structure and limits, semantic labels and sensor attributes. Without those, you have a pretty shape that falls through the floor.
a CAD model is not a simulation asset
The thing he says to watch is profiles. SimReady Foundation defines what an asset has to carry for a given use case, and ships validation tools to check it. That standard is what turns a mixed-supplier library into something composable rather than a pile of models with inconsistent units, origins and collision conventions. Anyone who has tried to drop two vendors' arms into the same scene knows which of those two outcomes is normal.
Built for agents to search
The library is indexed for agents, with natural-language search across it. The idea is that a model can find an asset, reference it into a USD stage and write the code that assembles the workcell. Ziegler describes the shape as the agent producing a scene or a config while a human reviews the file, and says it is the third time this month he has written about that same pattern.
That is also the quiet pressure on every arm maker not in the list. If an agent is picking parts to build a cell, it picks from what it can find.
Ziegler frames the release against NVIDIA's announcement just over a month ago that it is acquiring Hugging Face, and reads the drop as the two already working together. He is not claiming anything beyond that, and nobody has said what else is coming.
Shown versus claimed, this is a published asset library, not a benchmark or a performance result. The count is 2,000 plus, which Ziegler calls a good start rather than a finished catalogue. You can browse it yourself.
