How to interface Ubuntu 18 ROS robots with Isaac?

I want to simulate a hexapod robot in Isaac sim, but I couldn’t find much related information in the documentation. I heard that Isaac has recently implemented integration with ROS, but the recommended version by Isaac is Ubuntu 20.04, while my robot simulation model is based on Ubuntu 18.

Can you provide me with some suggestions or related information on how to achieve this? Thank you very much.

Hi @qthshiyuetian - Have you reviewed this doc? 6. ROS & ROS 2 Installation — Omniverse Robotics documentation

Thank you very much, I have already read this document. It describes how to install ROS on Ubuntu 18.04, but I see that Ubuntu 18.04 is only supported up to Isaac Sim 2022.2.0. Does this mean that if I install Isaac on 18.04, I will not be able to use later versions and new features of Isaac Sim? Does it mean that if I want to use it on the new Ubuntu 20.04, I need to compile my robot’s ROS project into the Noetic version? Both of these options seem a bit disappointing.

This means that we no longer QA Isaac Sim on Ubuntu 18.04, so things might work fine or there might be some issues, so you can try it and see if it works fine for you.
The other solution is to use docker container either for the ROS part or the Isaac Sim.
