Topic Description
Detailed Description
I’m trying to setup the ROS2 bridge according to the documentation, everyhting works fine until I try to listen to the topic /clock.
Nothing is found from my container, ros2 topic list doesn’t return a topic named /clock. I set up the RMW_INPLEMENTATION variable on both side, as well as the FASTRTPS_DEFAULT_PROFILES_FILE variable.
Isaac Sim is thus running fine on my Ubuntu 24, clock topic does exists since I can see it when I run ros2 topic list from foxy (even though its crashes seconds after), and I can even listen to this topic for a few seconds.
I can run two separates humble containers with the ros2 pub/sub example, it works fine as well.
The Ubuntu 22.04 and ROS 2 Humble combination is currently the latest officially supported configuration.
Separately, I have a question about the /clock topic: even in my ROS 2 environment, /clock does not appear when running ros2 topic list. Could you advise whether this topic requires enabling explicitly?
I thought that it could work with the ROS2 bridge, what’s the point of this section **ROS not installed locally**: If you are unable to install ROS on your system, you can still run the ROS Bridge on Isaac Sim. in the documentation then ?
I’m sorry, I meant that by following this documentation example , we see the /clocktopic show up.
Hi @olivier.lebec! Did you create an action graph to publish /clock? Or do you have other ROS running somewhere under the same network?
If you only start an empty scene in Isaac Sim with ros2 bridge, you should only see two topics: /parameter_events and /rosout
Yes, as in the documentation I created an action graph to publish /clock. Nothing else running under the same network. By empty you mean absolutely empty, not even with an action graph, right ? Because I run an empty physical scene but there’s the action graph running.
