I am wating to see a robot spread out to over 10' that can stop a charging high traction (tracked or multiple wheeled drive) robot out on its wingtips. My guess is that the plastic top will be a mess after the first day and suction will become less and less effective quickly. I am sure someone will have some neato tricks to stay planted up there but I just can not see how a wingspan at that large with only 130 lbs total will be able to resist a brute force attack on it.
