NVIDIA® Isaac ROS is a GPU-accelerated robotics software framework built on top of ROS 2, designed to help developers build high-performance robotic applications. It provides a collection of optimized ROS 2 packages for perception, AI inference, and sensor processing, all tuned to run efficiently on NVIDIA GPUs. By leveraging NVIDIA’s acceleration technologies, Isaac ROS enables robots to process large volumes of sensor data such as camera images and depth information in real time with low latency.
One of the key strengths of NVIDIA Isaac ROS is that it is fully compatible with ROS 2 interfaces. Isaac ROS packages use standard ROS 2 topics, services, and message types for input and output, allowing them to integrate seamlessly into existing ROS 2 systems. While ROS 2 handles communication and system orchestration, Isaac ROS focuses on accelerating compute-intensive tasks such as perception and AI inference using NVIDIA GPUs. This design allows developers to continue using familiar ROS 2 workflows while significantly improving performance on NVIDIA Jetson platforms and discrete GPUs.
How NVIDIA Isaac ROS Is Structured
NVIDIA Isaac ROS follows a layered architecture that connects real-world robotic applications with GPU-accelerated computing.
At the top layer are reference workflows and applications such as autonomous mobile robots (AMRs), drones, industrial robotic arms, and manipulators. These demonstrate how perception, localization, planning, and control work together in real robotic systems.
At the core are Isaac ROS accelerated ROS 2 packages, which include:
GPU-optimized image processing
Deep learning inference
Visual SLAM
Object detection and segmentation
Depth estimation
AprilTag detection
All of these are implemented as standard ROS 2 nodes, enabling drop-in integration into ROS 2 pipelines.
System communication and coordination are handled through the ROS 2 middleware, which manages message passing, synchronization, and data exchange using ROS 2 topics, services, and actions. This ensures smooth interaction between accelerated Isaac ROS nodes and other ROS 2 components in the system.
To achieve high performance, the architecture relies on optimization and execution frameworks such as TensorRT, Triton Inference Server, and the Graph Execution Framework (GXF). These frameworks optimize AI models, enable efficient inference execution, and manage parallel processing and data flow, resulting in low latency and high throughput.
At the foundation are accelerated libraries and hardware drivers. CUDA libraries provide GPU computing power, VPI delivers high-performance computer vision APIs, the TensorRT runtime executes optimized neural networks, and camera and sensor drivers enable fast and efficient data transfer from sensors to GPU memory.
Finally, the complete Isaac ROS stack is deployed on edge platforms, mainly NVIDIA Jetson devices such as Jetson Nano, Jetson Xavier, and Jetson Orin. These platforms power embedded robots and edge AI systems, enabling real-time, on-device inference without any dependency on cloud connectivity.
