What constitutes a “dead end” in the arena?
This is a touchy subject. I consider a “dead end” to be a position in the arena when three walls are within 2 or 3 inches of a 12″ robot. This means that there will be no tight passageways where only one robot can fit. If a robot can be approached from two different directions, I don’t consider the arena to have a “dead end”, as shown below.
