Dear Support
I hope that you can help me. After fighting through this description: Setting up Isaac™ ROS to work with ZED Cameras in ROS 2 - Stereolabs
There something is mentioned with Authorization required…
To keep that running I did:
xhost +local:root
and
./scripts/run_dev.sh -i ros2_humble.zed
-a “–runtime nvidia
-e DISPLAY=$DISPLAY
-v /tmp/.X11-unix:/tmp/.X11-unix
-v /usr/local/zed/settings:/usr/local/zed/settings
-v /usr/local/zed/resources:/usr/local/zed/resources”
Running isaac_ros_dev-aarch64-container
Creating non-root container ‘admin’ for host user uid=1000:gid=1000
Sourcing entryrypoint extension: /usr/local/bin/scripts/entrypoint_additions/zed-entrypoint.sh
Checking ZED SDK…
- /usr/local/zed/ exists. Changing permissions
- ZED SDK available:
Stereolabs ZED SDK Version : 5.1.1 - Stopping hotplug events dispatcher systemd-udevd [ OK ]
- Starting hotplug events dispatcher systemd-udevd [ OK ]
To run a command as administrator (user “root”), use “sudo ”.
See “man sudo_root” for details.
When I build and start the Ros2 topic as described here:
ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zed2i enable_ipc:=false
I entered the running container in another command windows and wanted to test the topics. But whatever Topic I am doing echo with there still no data comes out-.
What can I do to get it also for April tag?
Here an Example where no data comes out. It is on the second terminal which I entered with docker exec -it bash
root@ubuntu:/workspaces/isaac_ros-dev# ros2 topic list
/clicked_point

/parameter_events

root@ubuntu:/workspaces/isaac_ros-dev# ros2 topic echo /zed/zed_node/imu/data
Nothing comes out no matter which topic.
I also tested it on a normal PC not only Jetson.
What can I do?
