For example, if you want to build a mobile base with wheels and a camera, well a Raspberry Pi 4 will be perfect for that. Build and install the zed-ros2-wrapper, for example: Build and install image_transport_plugins. Run the zed-ros2-wrapper, observe errors: observe all of the above errors with both attempts. It seems like the republish tool wants a --remap for every applicable out, e.g. There is a required minimal structure for ROS2 to know those are parameters to load for a given node. This lets you retrieve the Left and Right rectified images published by the ZED node. I suppose that this is caused by the wrong handling of the params namespace by the applied patch. EDIT: I see I am mistaked; the first argument compressed is the input format, but this topic is uncompressed, and there doesn't seem to be a NULL topic; I would need a image_raw_sub to satisfy the current structure. ROS2 Image Pipeline Tutorial. But I noticed that only the first rosbag's image gets republished, but not any rosbag after that, unless I re-run the image transport code above after each rosbag finishes playingkind of a lame behavior in my opinion. As a result every machine running ROS2 can see every nodes/topics on all running machines in the same network. Expected behavior I checked with RQT and I can see source and target topics being created and populated: republish is doing his job, it just doesnt produce any log. Yes, I have tried all of the above as well (as per the Description): I can say that there are two problems generated by the same cause: the image_transport plugin does not correctly handle the namespace of the node.
