Isaac Cortex decision framework

Cortex

Programming behaviors for complex robots like cobots has always been a challenge. Cortex is a decision framework in Isaac Sim that greatly simplifies this programming task. By building a belief representation of the world in simulation, the robot can become aware of its environment and make decisions about the tasks it’s designed to complete.

Isaac Gym, a GPU accelerated RL tool

Gym

Reinforcement learning (RL) is a powerful machine learning method in robotics for performing complex tasks. Robots can be trained in “gyms” to complete tasks and acquire skills. NVIDIA Isaac™ Gym is a GPU-accelerated RL tool that significantly reduces the amount of time to train robots.

Omnigraph framework for visual scripting and programming

Omnigraph

Visual programming can greatly simplify application development and debugging. Omnigraph is the Omniverse framework for visual scripting and programming. Robotics applications are often represented as different compute nodes connected to each other, which makes them particularly well-suited for visual programming.

Gazebo - Isaac Sim Connector

Gazebo–Isaac Sim Connector

ROS developers can move simulations from Gazebo to Isaac Sim and vice-versa with the Ignition-Omniverse Connector. This allows developers to choose the right simulator for the right simulation task.

Explore key benefits of Isaac Sim.

Realistic simulation.

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.

With NVIDIA Omniverse, Isaac Sim benefits from Omniverse Nucleus and Omniverse Connectors, which enable collaborative building, sharing, and importing of environments and robot models in USD.

Now, you can easily connect the robot’s brain to a virtual world through the Isaac ROS/ROS2 interface, fully-featured Python scripting, and plug-ins for importing robot and environment models.

Why use Isaac Sim?



Next-level 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.

Seamless collaboration.

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.

Ultimate convenience.

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 of virtual robots more accessible.
You will have three options to access Isaac Sim in the cloud.



Generating synthetic data with Isaac Replicator.

Training perception models requires large and diverse datasets. Assembling these datasets can be costly, time-consuming, dangerous, and even impossible for certain corner cases. By using Omniverse Replicator for Isaac Sim, developers can bootstrap the training task. In the early phases of a project, synthetic data can accelerate proof of concepts or validate ML workflows. In later stages of a development cycle, 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 NVIDIA’s TAO Toolkit.

Simulating manipulation.

One of the key application areas for robots is for manipulators that can identify, pick up, and move objects. In a modern factory or warehouse environment, manipulators can greatly increase the efficiency and throughput of handling and sorting materials. But programming them has always been a challenge. To address this, we’ve introduced Isaac Cortex. Isaac Sim has built-in examples of common tasks like filling bins, stacking bins, and stacking blocks. These Python-based examples can be modified to work for your custom tasks. The UR10, Frank Emika Panda (Leonardo), and the low-cost DofBot are manipulator robots supported in Isaac and can jumpstart your projects.

 Simulating navigation for autonomous mobile robots

Simulating navigation.

Autonomous mobile robots must be able to move in their environments from point A to point B–enabled by the navigation stack. Isaac Sim supports the development and testing of your robots navigation capabilities by providing a complete example of how to use the ROS Navigation stack. In this example, the NVIDIA Carter robot moves its way autonomously through a warehouse environment. Similarly, the Isaac navigation stack running on Carter can be easily exercised in one the examples.

Importing robots and assets into Isaac Sim.

Importing assets into robotics simulators is critically important and oftentimes 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 Shapenet. The Shapenet importer provides access to a massive amount of 3D assets.
