Problem with renaming model_name

[Grigoriy0526]

Hello, I have a problem when starting the sydney_regatta world, if I rename model_name in the file competition.launch.py from 'wamv' to something else, an error occurs, what can such an error be related to?

• Ubuntu 22.04
• ROS 2, Humble
• Gazebo Sim 7.0.0
• VRX

I solved the bug yesterday, when spawning a vehicle with another name, the problem can be found in the vrx_urdf/wamv_gazebo/urdf/wamv_gazebo.urdf.xacro file. In line 103, you have to change
<child>wamv/base_link</child>
into
<child>$(arg namespace)/base_link</child>
Afterwards it should work fine.
I already started the pull request #644 to solve this problem
Tested in ROS2 Humble and Ubuntu 22.04
