As robotics systems become more complex, teams need to bridge the gap between prototyping and real-world testing. ROS 2 and NVIDIA Isaac Sim offer powerful solutions—one for building real-time control logic, and the other for physically realistic simulation. But until now, syncing the two often required brittle integrations or extensive custom coding.Champion bridges this gap.‍

🤖 What is ROS 2?

ROS 2 is the standard for robotic software architecture. It’s modular, scalable, and designed for real-time performance—making it perfect for:

Distributed robot control
Autonomy stacks
Hardware abstraction
Sensor + actuator communication

🌐 What is Isaac Sim?

Isaac Sim is NVIDIA’s high-fidelity robotics simulator built on the Omniverse platform. When integrated with ROS 2, it becomes a powerful environment for testing real-time robot control in simulated worlds.

Using ROS 2 inside Isaac Sim, you can:

Send velocity, joint, or trajectory commands to simulated robots through ROS topics
Subscribe to simulated sensors (camera, LIDAR, IMU) and use them in ROS perception nodes
Run ROS 2 navigation and manipulation stacks to move robots inside physics-enabled scenes
Test your control logic in loop using realistic physics before deploying to hardware
Use ros2_bridge or Isaac’s native extensions to sync messages between Isaac and your ROS 2 graph

This lets engineers write once in ROS 2 and validate across both virtual and physical robots—using Champion to manage assets, automate scene setup, and record outcomes.
