3528's going to get pushed out of the way. The increased length of their drive train makes the leverage a pushing team would have on them better. With the omni-ish drive they have going on, they're going to to get spun out of the way I think. They need more traction on the ground for this to work. 3553's robot seems to have more traction on their drive train. 8 friction wheels should do the job as long as those outside wheels stay against the ground and don't come up. They probably have too much friction to turn at that point actually, although if they wait to fold out their sides until they're in position, then they really wouldn't have to turn. And actually once they were in that position they would even be lined up with the poles for the minibot, they could just have their minibot attached to their fold out sides.
All in all I think 3553's design could be a huge 3rd alliance partner to any alliance that has 2 good scoring robots. Imagine them on the alliance at alamo with 16 and 148, although 3553 cant score an ubertube, it wouldn't matter because 148 would score it for them. Then 16 and 148 would score like crazy like they did while 3553 held the other alliance to 0 points. I think Einstein's going to be exciting this year
However, this is just my 2 cents.
