A list of NVIDIA Isaac components. [link]
-
The platform for connecting and developing OpenUSD applications.
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 Omniverse app/component in the entire software stack. For an example, Omniverse USD Composer (formerly Omniverse Create) and Omniverse USD Presenter (formerly Omniverse View) are apps built upon Omniverse Kit. They are software components that run on the Omniverse platform. -
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 Gym, Isaac Orbit, 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).

The term
Isaac Gymis ambiguous when viewed from a technical perspective. It's better to specify whether the mentioned Isaac Gym is based on Isaac Sim, or the preview version that does not base on Isaac Sim.Until Omniverse Isaac Gym functionality is feature complete, this standalone Isaac Gym Preview release will remain available.
The latest release of Isaac Gym (Preview Release) is Preview 4, and will not be further updated.

-
Isaac Orbit [docs][docs][arxiv][site][github]
a general repository based on Isaac Sim that features a number of GPU-accelerated simulation environments, a variety of motion generators, integrations with several reinforcement learning libraries, utilities for imitation learning, etc.
Released under the BSD 3-Clause License (source).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).
Omniverse Isaac Gym is a light-weight framework focusing on reinforcement learning tasks, while Isaac Orbit is a more general and modular framework that focuses on robotics applications. (source, source)
Personally, I think Isaac Orbit is preferred for general usages such as creating custom environments. However, if you are writing a research paper and just want to use built-in Omniverse Isaac Gym Environments for benchmarking, Omniverse Isaac Gym may be enough.

Isaac Robot Operating System (ROS) [link][github][docs]
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.
The term
Isaac ROSrefer to the packages for ROS 2, instead of Isaac SDK. Isaac ROS should not be confused with theROS & ROS 2 Bridgesin Isaac Sim, or theROS Bridgein Isaac SDK.
The packages (i.e., Isaac GEMs) are named asIsaac ROS <Package_Name>. Unfortunately, ambiguous terms such asIsaac Elbrusstill exist (source). Since the Elbrus package exist in both Isaac ROS and Isaac SDK, Elbrus should be refered to asIsaac ROS Elbrusfor preciseness.Before starting, please make sure your PC/Jetson hardware and software meet the system requirements. After checking the requirements, I suggest you start from the Nvblox tutorial below.
-
(Isaac ROS) Nvblox [github]

-
Isaac SDK [docs]
a toolkit for deploying GPU-accelerated algorithms on physical robots.a toolkit that includes building blocks and tools that accelerate robot developments that require the increased perception and navigation features enabled by AI.
Personally, I suggest using Isaac ROS instead of Isaac SDK for simplicity. Since researchers/engineers working on robotics tend to be more familiar with the Robot Operating System (ROS) than the
bazelcommand used in Isaac SDK. The Isaac GEMs and Isaac Applications included in Isaac SDK are also available in Isaac ROS.Isaac includes Isaac GEMs for both NVIDIA’s Isaac SDK Engine and ROS2. Isaac ROS has been more recently updated to contribute hardware acceleration to the growing ROS ecosystem. You can choose whichever one is more suitable for your project.
-- NVIDIA Forum Moderator (slightly rephrased)
The latest release of Isaac SDK is 2021.1, since the future roadmap of Isaac SDK is still under development (source, source, source, source).

Isaac Manipulator [link]
a collection of foundation models and modular GPU-accelerated libraries that help build scalable and repeatable workflows for dynamic manipulation tasks by accelerating AI model training and task (re)programming. It’s revolutionizing how robotics software developers can leverage customized software components for specific tasks such as machine tending, assembly tasks, etc., enabling manipulation arms to seamlessly perceive and interact with their surroundings.
Personally, I think these GPU-accelerated packages would be released as Isaac ROS packages in the future. For an example, the cuRobo library may be packaged as a cuMotion ROS 2 package. This means we can expect more versatile and powerful Isaac ROS packages than currently released packages such as Isaac ROS Pose Estimation for manipulation tasks.
