# NVIDIA Isaac Sim  

NVIDIA Isaac Sim™ is an open-source reference framework built on [NVIDIA Omniverse](/omniverse)™ that enables developers to simulate and test AI-driven robotics solutions in physically based virtual environments.  
  
Isaac Sim is fully extensible. This enables developers to build [Universal Scene Description (OpenUSD)](https://www.nvidia.com/en-us/omniverse/usd/?ncid=pa-srch-goog-230293-vt49&amp;_bt=697115562887&amp;_bk=openusd&amp;_bm=p&amp;_bn=g&amp;_bg=162278196418&amp;gad_source=1&amp;gclid=EAIaIQobChMI3YzrqYG7hgMV2zWtBh2QhwopEAAYASAAEgJbVfD_BwE)-based custom simulators or integrate core Isaac Sim technologies into existing testing and validation pipelines.

## How Isaac Sim Works

Isaac Sim facilitates three essential workflows: generating synthetic data for training or post-training robot models used for perception, mobility, and manipulation. It also enables validating robot stacks through software and hardware-in-loop testing and enabling [robot learning](https://www.nvidia.com/en-us/use-cases/robot-learning/) through NVIDIA [Isaac™ Lab](/isaac/lab).

## Key Features

### Pre-Populated Robots and SimReady Assets  

Isaac Sim supports a wide range of robots with differential bases, form factors, and functions built on OpenUSD that have the ideal physics properties to speed up robot simulation.

- 
**Humanoids:** 1X, Agility, Fourier Intelligence, and Sanctuary
- 
**Manipulators:** Fanuc, KUKA, Universal Robots, and Techman
- 
**Quadrupeds:** ANYbotics, Boston Dynamics, and Unitree  

- 
**AMRs:** idealworks, iRobot

  
Access over 1,000 [SimReady](https://www.nvidia.com/en-us/glossary/simready/) 3D assets—including conveyors, boxes, and pallets—to build your simulation scene. Isaac Sim now supports robot and sensor schema, making it much easier to define metadata.

### Bootstrap AI Model Development

Bootstrap AI model training with [synthetic data generation](https://www.nvidia.com/en-us/use-cases/synthetic-data/), where data is limited or restricted. Developers can further use this data to augment with NVIDIA [Cosmos™ world foundation models](https://www.nvidia.com/en-us/ai/cosmos/) and post-train vision-language-action models such as [GR00T N1.5](/isaac/gr00t).

### Render Real-World Data in Simulation

[NVIDIA Omniverse NuRec](https://docs.omniverse.nvidia.com/materials-and-rendering/latest/neural-rendering.html)neural rendering capabilities speed up simulation by turning captured sensor data into interactive simulation scenes.

### Modular Architecture for Robotics Workflows

Create custom workflows or integrate with your existing ones to support various types of robots, including [humanoids](https://www.nvidia.com/en-us/use-cases/humanoid-robots/), manipulators, and autonomous mobile robots (AMRs).
