[hmpcjayaweera]

I'm using ros2 humble with a robot in gazebo. The robot localization package run without any error, the pose with coverience (3axis in the map) is quickly move to the robot position in the map when trigger the localization. However, the output of the "ros2 topic echo l/ocalization_result" is not given. Please see the attached ros2 topic list, RQT graph, and ros2 node info /occupancy_grid_localizer /occupancy_grid_localizer.

Please can i know how to get the localized potion information.
