Hello i have followed this example ROS2 Navigation and i am using ros2 humble.
The first time i followed this example i could see the occupancy map loaded in rviz2 automatically while i was running ros2 navigation example is isaac sim but now i am unable to see the occupancy map in rviz2 therefore i can not give 2D pose estimation and Nav2 goal position from rviz2.
I have carefully followed the instruction as the tutorial says. can someone please guide me why i am unable to see occupancy map ?
This is how it looks on rivz2
Could it be because of fixed frame? when i changed fixed from map to odom i can only see TFs in the center of rviz2 without map though.
Please guide.
