Cannot run the navigation example with ros2 humble

I tried to run the nav2 example through the tutorial(, but it didn’t show the results as the tutorial.
when I start rviz, I get errors:

and it doesn’t show the map image in rviz:

I use the navigation example with isaac sim 2022.2.1 and ros2-humble.

Are you getting messages in any of the mentioned topics?


Try sourcing a terminal and doing ros2 topic echo /map

I tried it,and did’t get any message in /map, but I can get some message in /tf | /odom | /scan

Hi @mmmmark - Please try now this with the latest Isaac Sim release.

I have tried the Isaac Sim 2023.1.0, but when I open the navigation example scenes, I only see a car without any assets

Hi @mmmmark - Did you update the ROS before running the example? Running the new Isaac Sim ROS/ROS2 Bridge (Isaac Sim 2023.1.0 Release onwards) - #3 by scn
