I didn't keep track of my work, but essentially, I drew a rectangle inside an 80 inch diameter circle, with the corners being located on the circle. I assumed a fix robot width of 28 inches, and tried to find how far forward once could extend. The answer I got was 74.9ish inches total. Subtracting the robot length (assumed to be 38") this leaves you with about 37" to play with.

It gets worse...I believe that this is without bumpers. Until someone like the GDC tells me otherwise, the bumpers do count as having to fit into the 80" circle. (Now, they don't have to be the full distance around, so you might be able to get away with these measurements, but I'd check them with bumpers.)
