SimReady Assets

SimReady, short for "simulation-ready" is a standard for physically accurate 3D assets that capture real-world properties, behaviors, and data bindings. Built on OpenUSD, SimReady assets encode geometry, physics, appearances, annotations, and other attributes needed to accurately represent and simulate real-world objects.

In NVIDIA Isaac Sim, a rich collection of SimReady assets and robots is available to help you build and customize virtual environments. The Isaac Sim Assets Library can be accessed through the Isaac Sim Content Browser, offering assets across multiple categories including robots, sensors, and environments.

Additionally, our code base provides USD files for the Unitree H1-2 and RealMan WR75S  robots, both converted directly from their official URDF sources. To assist your workflow, we have prepared a detailed guide detailing how to convert robot assets to SimReady format and use them effectively in simulation.
