The model paths in models/curiosity_path/urdf/curiosity_mars_rover.xacro are wrong, they are missing the /models prefix.
See issue #5 for more details
To reproduce:
# from the space-ros workspace folder
colcon build --packages-up-to simulation
source install/setup.bash
xacro -o curiosity_mars_rover.xacro.urdf curiosity_mars_rover.xacro
This will generate the urdf file but when loaded at runtime, errors will occur that it can't find the paths for the files.

The solution to this is to:
add the /models path correctly to the curiosity_mars_rover.xacro file
use that file directly in the mars_rover.launch.py file
remove the curiosity_mars_rover.xacro.urdf file and use xacro at runtime directly
The model paths in
models/curiosity_path/urdf/curiosity_mars_rover.xacroare wrong, they are missing the/modelsprefix.See issue #5 for more details
