I have to say that 1114 (and likely the other triplets, though I've only seen 1114 on my field so far) has a really nice adaptation of tank tread. I always thought it would be slow and incredibly hard to turn, but somehow, they make it look easy. They do "hop" a bit, but its a lot more manuverable than I would have expected.
That said, unless we have to climb stairs or anything else strange like that, I think 1511 is in love with our current drivetrain. We have two custom center 8" traction wheels, and four AM omni wheels on all corners. The thing pivots on a dime, but much to our suprise, we were able to push around every robot at FLR!! Its also an advantage because when other teams try to push us, our driver just spins around them and shoots from somewhere else. At the risk of giving away our secrets, I really wanted to share this with other teams that might be looking for a simple option. I will admit, we NEVER thought we could be a defense bot, but after finding we could push a lot of teams, we thought much more of our drivetrain
