NVIDIA Isaac Sim

NVIDIA's Omniverse-based, open-source robot simulator built for high physical and visual fidelity.

Isaac Sim is NVIDIA's reference robot simulation application, built on the Omniverse platform: scenes are described in OpenUSD, physics runs on PhysX, and rendering runs on RTX. It can import robots and scenes from CAD, URDF, or MJCF, simulate sensors such as cameras and lidar, batch-generate synthetic data by randomizing lighting, color, and position, and supports software-in-the-loop/hardware-in-the-loop testing along with a ROS 2 bridge. It's been open source on GitHub under Apache 2.0 since 2025. Its role is to be the high-fidelity simulator, while large-scale policy training is usually handed off to Isaac Lab, which is built on top of it. As of September 2026, the latest stable release is 6.1, with 7.0 available as an alpha preview.

ExampleBuild a warehouse scene in Isaac Sim, randomize the crate textures and lighting, and batch-render labeled images to train a detection model.
