I am working on a t-shirt shooting robot project. I want to know what type of wheels are the best for driving in the street/on the sidewalk, possibly a gym floor (without scuffing too bad) and rubberized running track. We currently are working with an AM14u 2014 KoP chassis with AM-2256 white rubber wheels (is it possible to swap any other type of wheels out and still use the same chassis?). Is there anything that I could do to modify the wheels to use them on concrete/cement? I've done a bit of research and I apologize if there are any threads already covering this (I searched).
