1. [Home](/) [Isaac](https://developer.nvidia.com/isaac) Isaac Sim # NVIDIA Isaac Sim NVIDIA Isaac Sim™ is an open source reference framework built on [NVIDIA Omniverse](/omniverse)™ libraries for robotics simulation, testing, and synthetic data generation in physically based virtual environments. Isaac Sim is fully extensible, so developers can build custom [OpenUSD](https://www.nvidia.com/en-us/glossary/openusd/)-based simulators or integrate framework capabilities into existing testing and validation pipelines.

[Download Now From GitHub](https://github.com/isaac-sim/IsaacSim "Download on Github")[Isaac Sim on Brev](https://docs.isaacsim.omniverse.nvidia.com/5.1.0/installation/install_advanced_cloud_setup_brev.html "Isaac Sim on Brev") * * * ## How Isaac Sim Works Isaac Sim can ingest data from multiple sources—such as computer-aided design (CAD), Unified Robot Description Format (URDF), or real-world captures via [NVIDIA Omniverse NuRec](https://docs.nvidia.com/nurec/index.html) and Isaac TeleOp—and convert it into USD. Developers then assemble simulation scenes by assigning materials, enabling physics, and configuring robot and sensor models. From there, robots can be used with [NVIDIA Isaac Lab](/isaac/lab) for [robot learning](https://www.nvidia.com/en-us/use-cases/robot-learning/) and simulated in Isaac Sim. Isaac Sim also supports controllable synthetic data generation, letting developers build custom data pipelines that complement their existing data sources. That data can be further augmented with NVIDIA Cosmos™ world foundation models. Finally, developers can train perception and mobility stacks in simulation and evaluate the end-to-end system in Isaac Sim using software-in-the-loop or hardware-in-the-loop testing. ![A diagram showing how NVIDIA NeMo Retriever works from data ingestion to information retrieval.](https://developer.download.nvidia.com/images/isaac/sim/isaac-sim-main.png) _NVIDIA NeMo Retriever collection of NIM microservices are used to build optimized ingestion and retrieval pipelines for highly accurate information retrieval at scale._ ### Isaac Sim Documentation Browse documentation and learn how to get started on Isaac Sim.
