Pictures or it didn't happen ;-)

Now I KNOW you are pulling my leg!!!

Now you've got me blushing. To my knowledge the only thing you may be able to argue was earlier was the robot that Tony and Bob's old Raytheon Team built in 97 which docked with the goal (the tube tree) and spun it. Man, nobody wanted to play against them on Saturday (this was the days of 1 on 1 on 1 and Saturday morning was a double elim tourney). As recall, they defeated Wildstang that year when a branch of the spinning tree knocked them over as it tried to dock with the goal after Raytheon had docked and the dervish had begun. Back to being first, it is a fleeting thing. The technology was advancing such that it was going to happen sooner or later.

While I am posting, I have an idea for a crab chassis morphology that I have never seen in FIRST before. I think it could be 4 ways of awesomeness.

But it is only a twinkling in my eye at this point. If I can get my rookies organized enough that we can prototype it before the season starts, AND if it works like I think it will, AND if the game is sideways motion friendly... ...all ya'll may get to see it at the Boston Regional ;-)
