Reuse of launch file

[ROxX]

I am trying to use the launch file for my own mecanum_wheel package. I changed the package name and the urdf name and the name in the parameters location. Yet I get an error, Is there anything obviously wrong Thanks

Hi @ROxX ,

The error seems to be quite obvious.

It asks you to check if the xacro file is well formed and if it states the XML namespace xmlns.

What you need to do:

1. Go through your Xacro file(s). Check if file references are correct and if every XML tag is properly indented and closed.
2. Check if you have added the xmlns to all the dependent xacro files.

The error also states that there is no element found in line 29, column 0 of the wheel_1a.urdf. So you need to check one line above and one line below to know if the file syntax is continuous.
Is the wheel_1a.urdf a xacro file? Check that.

With the error that you have received, I don’t see an issue with your launch file but only in your urdf/xacro files. Check every file from the beginning for syntax consistency. Doing these steps should fix your issue!
