As per the architecture, the Realsense data must flow through the splitter to reach the isaac_ros_vslam node. I found this at https://nvidia-isaac-ros.github.io/repositories_and_packages/isaac_ros_nvblox/isaac_ros_nvblox/troubleshooting/troubleshooting_nvblox_realsense.html
But when the isaa_ros_vslam is launched using ros2 launch isaac_ros_visual_slam isaac_ros_visual_slam_realsense.launch.py , I find no realsense_splitter node in the rqt_graph. Also the topics were listed to check its existence, but there’s no topics as well. I have attached the output visualized in rqt_graph.
Welcome to the Isaac ROS forum.
We are investigating this issue. I will reply in more detail as soon as possible.

If you install the packages by “apt-get”, the realsense splitter seems not be included.
you need to build realsense splitter by yourself
