On Ubuntu 24.04.03 with latest updates, I tried Isaac Sim 5.1 with ROS2 Jazzy from Docker as described in the documentation, same result as using ROS2 Jazzy installed natively. The Navigation example loads but does not receive costmap in RVIZ.
I used the clear caches script and also started isaac sim 5.1 once with the –reset-user argument to get it back to all default settings.
Previously in this thread I showed how I used the build_ws workspace, which did not end up launching due to a dependency. But according to the documentation the build_ws is only required for custom ROS2 packages. So assuming there are no custom packages, here are the specific steps I’m taking on Ubuntu 24.04 without build_ws:
In a new terminal:
export isaac_sim_package_path=$HOME/isaacsim_5.1
export ROS_DISTRO=jazzy
export RMW_IMPLEMENTATION=rmw_fastrtps_cpp
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$isaac_sim_package_path/exts/isaacsim.ros2.bridge/jazzy/lib
$isaac_sim_package_path/isaac-sim.sh
This starts up Isaac Sim 5.1. The following are the last few messages in the terminal window:
[6.256s] Attempting to load system rclpy
[6.256s] Could not import system rclpy: No module named 'rclpy'
[6.256s] Attempting to load internal rclpy for ROS Distro: jazzy

[6.523s] app ready
[8.256s] Isaac Sim Full App is loaded.
Then at the top of the GUI, I select Window → Examples → Robotics Examples.
In the Robotics Examples tab, I select ROS2 → Navigation → Nova Carter and then I load the scene.
Then in a new terminal window:
export RMW_IMPLEMENTATION=rmw_fastrtps_cpp
cd IsaacSim-ros_workspaces
cd jazzy_ws
source /opt/ros/jazzy/setup.sh
colcon build
source install/local_setup.sh
ros2 launch carter_navigation carter_navigation.launch.py
and I get an RVIZ display that is almost correct, and looks like it has a functioning Lidar, but no costmap
If I use ROS2 Jazzy from Docker, I get the exact same results.
If I use ROS2 Humble from Docker, it works.
The documentation says Jazzy is fully supported in Isaac Sim 5.1 on Ubuntu 24.04, so please let me know what I should try or if I have anything wrong in starting Isaac Sim or launching ROS2.
