It seems you skipped some units and/or commands before getting here. You must run

source /home/simulations/ros2_sims_ws/install/setup.bash

before the package can work properly.

Please also note that the launch file is loc_nav.launch.py not leo_nav.launch.py.

4

Remember that you have to execute this source in any terminal that executes preinstalled in the system roslaunches like the loc_nav.launch.py: “source /home/simulations/ros2_sims_ws/install/setup.bash”

I think I didn’t miss any units. Please help me to correct it. What should I do to make it run perfectly. The command that you suggested isn’t fixing it.

In another post of yours, it seems you have the leo_description package in your workspace. Please remove that, recompile your workspace, and try again:

cd ros2_ws/src
rm -rf leo_description/
colcon build
source install/setup.bash
source /home/simulations/ros2_sims_ws/install/setup.bash
ros2 launch leo_description loc_nav.launch.py

If it does not work, please upload a screenshot showing which command failed.
