Explore Key Benefits of Isaac Sim
Isaac Sim makes the most of the Omniverse platform’s powerful simulation technologies. These include advanced GPU-enabled physics simulation with NVIDIA® PhysX® 5, photorealism with real-time ray and path tracing, and MDL material definition support for physically based rendering.
Modular Architecture for a Variety of Applications
No simulator can address every robotics simulation challenge. But Isaac Sim is built to address many of the most common use cases, including manipulation, navigation, and synthetic data generation for training data. Its modular design also means the tool can be customized and extended to many new use cases.
Seamless Connectivity and Interoperability
Isaac Sim benefits from Omniverse Nucleus and Omniverse Connectors, which enable collaborative building, sharing, and importing of environments and robot models in Universal Scene Description (OpenUSD).
Now, you can easily connect the robot’s brain to a virtual world through the Isaac ROS/ROS 2 interface, full- featured Python scripting, and plug-ins for importing robot and environment models.

Get Exceptional Performance and Scalability
Isaac Sim is available on Omniverse Cloud and from leading cloud services, so you always have access to powerful simulation tools that can scale up rapidly. This will help you with most compute-intensive simulation tasks like CI/CD and synthetic data generation.
Teams across the globe can work together in real time to build AI robots with Isaac Sim. You can now simulate robots anywhere and on any device.
With just a few clicks, you can access Isaac Sim on AWS RoboMaker. On NGC, we also have an Isaac Sim container that lets you move that containerized application to the cloud of your choice.
Isaac Sim on the Omniverse platform makes testing and training virtual robots more accessible.
You have three options for accessing Isaac Sim in the cloud.
Synthetic Data Generation With Omniverse Replicator
Training perception models requires large and diverse datasets. Assembling these datasets can be costly, time-consuming, dangerous, and even impossible for certain cases. Omniverse Replicator is a core extension of the Omniverse platform that lets developers build custom synthetic data generation tools and pipelines, and bootstraps the training task. In the early phases, synthetic data can accelerate proof of concepts or validate ML workflows. In later stages, real data can be augmented with synthetic data to reduce the time for training a production model. Isaac Sim has built-in support for domain randomization, allowing for changes in texture, colors, lighting, and placement. It also features support for different types of data, including bounding boxes, depth, and segmentation. Developers can output the datasets in KITTI format, making it easier to use the NVIDIA TAO Toolkit..

Importing Robots and Assets Into Isaac Sim
Importing assets into robotics simulators is critically important and often a significant challenge when setting up a training or testing scenario. Using the powerful connector capabilities built into Omniverse, Isaac Sim has built-in support for popular product design formats. The advanced URDF importer has been tested on multiple robot models. Additionally, CAD files can be imported directly from Onshape and from STEP files with minimal post-processing.
To make it easier to add assets to different environments, Isaac Sim supports the Shapenet importer, which provides access to a massive amount of 3D assets.
