Our robot, team 358, is clearly an arm robot, but since we can shoot from at least 8 feet from the overpass while on the move, it posseses many of the advantages of a shooter. I am sure there are other similar designs out there. So framing the debate as arm vs. shooter ignores the existence of these hybrid bots. In the coming weeks we will see how this plays out.
