NVIDIA Isaac Summary

An unofficial summary of NVIDIA Isaac.

The following is a list of NVIDIA Isaac components. [link]

Component Descriptions

Overview

  • Omniverse [link][docs][github][youtube]

    The platform for connecting and developing OpenUSD applications.

    -- NVIDIA Omniverse

    It is worth noting that Omniverse is a platform, and is not a standalone application. Therefore, the term Omniverse, should not be used to refer to a specific component, but to the entire platform. Technically speaking, there is no such thing as an app/component named Omniverse in the entire software stack. For an example, Omniverse USD Composer (formerly Omniverse Create) is a template app built upon Omniverse Kit. It is a piece of software that run on the Omniverse platform. Before using any Omniverse-based applications, make sure your system meets the hardware and software technical requirements.

  • Isaac [link]

    The NVIDIA Isaac robotics platform includes a full suite of GPU-accelerated innovations in AI perception, manipulation, simulation, and software.

    -- NVIDIA Isaac

    Isaac stands as NVIDIA's GPU-accelerated solution for robotics, which refers to the robotics platform instead of a specific software component. Alongside essential tools for general AI applications (such as TensorRT, TAO Toolkit, and Triton Inference Server), NVIDIA Isaac components can be categorized into two main branches: (1) Isaac Sim (including Isaac Sim, Isaac Lab, etc.) for simulation, which currently requires x86 CPUs and RTX GPUs for acceleration. (2) Isaac ROS for deployment, which can run on both PCs (x86 CPUs) and on Jetson hardware (ARM CPUs).

(Omniverse) Isaac Sim

  • (Omniverse) Isaac Sim [link][docs][ngc][dli][dli][youtube]
    a robotics simulation toolkit based on Omniverse.

    a scalable robotics simulation application and synthetic data-generation tool that powers photorealistic, physically accurate virtual environments.

    -- NVIDIA Isaac Sim

    Before starting, please make sure your hardware and software meet the system requirements.

    Technically, Isaac Sim is an app built upon Omniverse Kit, which is a SDK for building apps upon the Omniverse platform. The simulation is accelerated by PhysX, while the scene is rendered through RTX rendering.

    To install Isaac Sim, follow one of the following methods:

    1. Binary Installation:
    2. Pre-built Docker Container:
      Docker containers are especially useful for quickly testing the software without the need to install it on the host system. However, Ubuntu is required for this. (I haven't tested it on WSL 2)
    3. Install with PIP (Experimental):
    4. [Deprecated on October 1, 2025] Omniverse Launcher:

    • [Deprecated on October 1, 2025] Omniverse Nucleus and Omniverse Cache.

    -- NVIDIA Replicator

Isaac Lab

  • Isaac Lab [link][docs][docs][github]
    an open-source platform based on Isaac Sim, currently the de facto framework for robot learning in Omniverse.
    Formerly Isaac Orbit.

    a unified and modular framework for robot learning that aims to simplify common workflows in robotics research (such as RL, learning from demonstrations, and motion planning). It is built upon NVIDIA Isaac Sim to leverage the latest simulation capabilities for photo-realistic scenes, and fast and efficient simulation.

    -- NVIDIA Isaac Lab

    For more details on the position of Isaac Lab in the Isaac ecosystem, see the Isaac Lab Ecosystem.

  • [Deprecated] Isaac Orbit, (Omniverse) Isaac Gym, Isaac Gym (Preview Release).

  • Project GR00T (Generalist Robot 00 Technology) [link] [blog]

    a research initiative and development platform for general-purpose robot foundation models and data pipelines to accelerate humanoid robotics.

Isaac ROS

  • Isaac Robot Operating System (ROS) [link][github][docs][ngc]
    a collection of GPU-accelerated ROS2 packages (i.e., Isaac GEMs) and pipelines.

    a collection of hardware-accelerated packages that make it easier for ROS developers to build high-performance solutions on NVIDIA hardware.

    -- Isaac ROS

    In legacy robotics deployment systems, ROS1 is commonly used but lacks support for key use cases such as multi-robot systems, real-time systems, and production-ready environments. Therefore, ROS2 was developed to address these issues. However, using ROS2 can still present challenges, such as reproducibility across different systems and efficient GPU communication between ROS nodes. Isaac ROS, a collection of GPU-accelerated ROS2 packages and pipelines, addresses these challenges by (1) adopting a workflow based on the NVIDIA Container Toolkit (previously NVIDIA Docker) to ensure reproducibility across systems, allowing near-identical deployment experiences across systems with x86 and ARM CPUs, and (2) enabling efficient GPU communication between ROS nodes by reducing memory copies between GPUs and CPUs through NITROS.

    Mainstream robotics applications can be roughly categorized into manipulation and navigation tasks. To address these tasks, Isaac Manipulator and Isaac Perceptor were developed as reference workflows. These workflows will be described in detail below.

    The term Isaac ROS refer to the packages for ROS 2, instead of Isaac SDK. Isaac ROS should not be confused with the ROS & ROS 2 Bridges in Isaac Sim, or the ROS Bridge in Isaac SDK.
    The packages (i.e., Isaac GEMs) are named as Isaac ROS <Package_Name>. Unfortunately, ambiguous terms such as Isaac Elbrus still exist (source). Since the Elbrus package exist in both Isaac ROS and Isaac SDK, Elbrus should be refered to as Isaac ROS Elbrus for preciseness.

    To get started quickly, follow these steps:

    1. Ensure your PC/Jetson hardware and operating system meet the system requirements. For setting up your Jetson environment, please refer to the Jetson section.
    2. Set up your system environment.
    3. Configure your development environment.
    4. (Optional) To feel the power of Isaac ROS, simply follow the Nvblox tutorial for a quick introduction.

    Some of the Isaac ROS packages are listed below:

    • (Isaac ROS) Nvblox [github]

      processes depth and pose to reconstruct a 3D scene in real-time and outputs a 2D costmap for Nav2. The costmap is used in planning during navigation as a vision-based solution to avoid obstacles.

      -- Isaac ROS Nvblox

      This packages includes the use of the Isaac ROS Visual SLAM package, which uses cuVSLAM as the underlying algorithm.

    • (Isaac ROS) NVIDIA Isaac for Transport for ROS (NITROS) [github]

      the NVIDIA implementation of type adaption and negotiation for ROS2 that eliminates software/CPU overhead and improves performance of hardware acceleration.

      -- Isaac ROS (slightly rephrased)

    • etc.

  • Isaac Manipulator [link][docs][github]
    a collection of Isaac ROS packages for manipulation tasks.

    a reference workflow of NVIDIA-accelerated libraries and AI models that enables developers to build AI-enabled robot arms, or manipulators, that can perceive, understand, and interact with their environments.

      -- Extended Robot Description Format (XRDF)

    • (Isaac ROS) cuMotion [docs][github]

      provides CUDA-accelerated manipulation capabilities for robots in ROS 2. It provides two main capabilities: (1) Motion generation for robot arms via integration of cuMotion into MoveIt 2, and (2) Segmentation of robots from depth streams using cuMotion’s kinematics and geometry processing functions to accurately identify and filter out parts of the robot. This allows reconstruction of obstacles in the environment without spurious contributions from the robot itself.

Epilogue

Please open an issue if you have spotted any errors or have questions regarding this document. For questions regarding the Isaac components, I recommend first going through the Known Issues of Isaac Sim, Known Issues of Isaac Lab, Troubleshooting Guide for Isaac ROS, then considering asking in the NVIDIA Developer Forums under the Isaac topic.

I have documented some bug fixes and workarounds for Isaac in the j3soon/isaac-extended repository. I recommend also checking out that repository for reference.
