If you want to set up the footprint of a "non-comercial" robot (DIY) you should write down the coordinates on the common costmaps yaml. I have a rectangular sized robot with the base_link frame at the center of that rectangle, so I have 4 coordinates written in counterclockwise direction. So, for example, if I have something like this:

My footprint should be: [[-10, -20], [10, -20], [10, 20], [-10,20]].

Hope this can help you!
