I also <3 the end effector and part of me (the very tiny egotistical part, mind you
) would like to think that 22 drew some inspiration from us when we came down for the Southern California Regional. We were able to grab and stack 2 consistently when everything was mechanically sound in our robot, albeit with a much more inconsistent system, which ultimately proved to be our downfall. 22 originally had a gripper just like 254's and they proved to be adept with that as well, but I remember them being concerned with the idea of stacking two tetras with a new design. I also remember watching one of their matches in Atlanta as soon as I could get home after practice on the Friday afternoon and seeing them seemingly stack 2 and going
. The beauty of this was that they didn't have to change the robot significantly at all!
Said it before and I'll say it again, we cant wait for 22 to come back up here next year, almost as much as we wish we were down there now, or at least at championships.
