After manually doing to parsing from urdf to sdf using
gzsdf print I get garbage at the beginning of the file:
[1;36mDbg[0m [base_footprint] has no parent joint <sdf version='1.3'> <model name='kobuki_standalone'> <link name='base_footprint'>
Before I am able to use the SDF file I have to remove this line.
I'm running 1.3 with Groovy.
PS: Why can't I choose 1.3 in the pull-down menu, when creating an issue? Only 1.4, 1.5 and 2.0 is available.
