I can't say who had the best robot this year.. I'm not that good. However, I stand by my favorites:
33 -- Tough break for you guys in the Archimedes elims. I just watched all your archived matches, and you guys still amaze me. You consistently knocked off the 10 point ball in autonomous and delivered a massive amount of balls to your human player. I saw you guys get around major defense, picking up many balls and delivering them just the same. The defense perhaps stalled your plans by 5-10 seconds. Your hanger also wasn't that bad at all. For something put together at the last minute, it did function better than some of the other mechanisms I've seen this year. On a down note, your method of getting on the ramp made it easier to prevent you from hanging. All around, you guys are still my favorite

.
45 -- Tough break for you guys as well. You do balls just as well as 33, but in a smaller amount of space. Once you slurp the big ball, your control of it is deadly. I dunno, you guys were just really amazing.
469 -- Your
drivers were top notch. They squeezed every bit of ability out of your robot. Amazing.
71 -- I'll admit right out, you guys weren't a favorite of mine. At all. I thought a 45 + 71 alliance would've done well at MWR and that a 33 + 71 would've happened at the Championship Event, because 45 would've been taken in the first round by the number one seed, but I'm finally beginning to understand that not all things happen the way you think. Your driveteam knows what they are doing.
Among the best, in my mind: 33, 45, 571, 60, 254. I'll leave the other teams for other posters to make known. A personal top 5 is good enough for me.
PS: Can we see a 60 + 45 vs. 33 + 71 at this year's IRI? It could be in the qualification or elimination rounds, I don't care. I just want to finally know what would have happened.
