Integrating Isaac ROS Centerpose with Ubuntu 20.04 running ROS 1 Noetic

Hi,

I previously set up the Isaac ROS Centerpose module using ROS 2 Humble on an Ubuntu 22.04 machine and was able to run it successfully inside a container. The camera node (RealSense) was running outside the container, and I could subscribe to its topics from inside the container without issues.

Now, I’m trying to replicate this setup on a new machine running Ubuntu 20.04 with ROS 1 Noetic, and an RTX 4060 GPU. I’m attempting to use the Isaac ROS NITROS Bridge to forward /image_rect and /camera_info_rect from ROS 1 into the ROS 2 container so CenterPose can consume the data.

I launched the bridge using:

docker run -it --cap-add=SYS_PTRACE --privileged --network host --pid host --ipc host --runtime nvidia --name nitros_bridge -e FASTRTPS_DEFAULT_PROFILES_FILE=/usr/local/share/middleware_profiles/rtps_udp_profile.xml --rm nitros_bridge:latest nitros_bridge_convert_forward.yaml nitros_bridge_convert_forward.launch

It partially launches, but I hit some issues:

It then kills a bunch of nodes, re-launches, and logs show that the nodelets are starting.

However, there are warnings like:

    The parameter 'services_1_to_2' either doesn't exist or isn't an array

    The container doesn’t fully start for me to run the remaining steps

I’m also unsure if this is the intended use case for the NITROS bridge, or if I’m going about this the wrong way.

As a workaround, I’m trying to use rosbridge WebSockets to send the image stream from ROS 1 to the container — but the bandwidth overhead is making it impractical for video/image data.

My Questions:

Is the Isaac ROS NITROS Bridge the right tool to bridge image and camera_info topics from ROS 1 Noetic (host) to ROS 2 (inside container)?

If so, how can I properly resolve the launch issues and ensure the bridge functions correctly?

If not, what’s the recommended way to get high-bandwidth topics like image streams from ROS 1 into a ROS 2 container for modules like CenterPose?

Any advice would be greatly appreciated. Thanks!

Hi @amanickapraveen

Thank you for your post.

First thing, I kindly suggest working with ROS 2 instead of ROS 1, a reminder that coming 31st of May, ROS Noetic will no longer be supported by the ROS community.

Have you followed all steps in Isaac ROS NITROS Bridge — isaac_ros_docs documentation ?

Yes, Isaac ROS Nitros bridge is the right tool, but remember that it will no longer be supported in the next Isaac ROS releases.

Best,
Raffaello
