I (shane.palm) had the priveledge of being a student on The Beach Bots in my high school years. I now lead The Beach Bots and Quebecalgal is also a mentor. The FIRST Robotics program is often coined "A sport for the mind". High schools form teams and build robots that compete head-to-head. It's very intensive from January to April and we'll be spending most of our evenings and weekends building our robot nearby the cache location. For more information, go to usfirst.org. You'll also get a better taste for it as you figure out this puzzle.
NAA BB.CCC, WXXX YY.ZZZ
(The Beach Bots), drop the last digit = AA
(The Greybots) - (Spartan Robotics) + 50 = BB
(The Holy Cows), swap the middle digits and remove the first digit = CCC
(The Cheesy Poofs) - 136 = XXX
39491 / (The D’Penguineers) = YY
(RAWC) - (Beach Cities Robotics) - 59 = ZZZ
There is an old team medal for FTF! Also, the cache is starting out with an astronaut TB - it's there already, but quebecalgal will log the drop when the cache is published.
