you could have done your 65 joke in only one post . . . .
anyway, I was at Stl and I don't think I saw a single KOH bot work.
Many teams tried to use suction cups alone for traction (45) but I think the whole point of a suction cup is to stick it down, then pull up on it. If you have a really good cup it can probably take around 100 lbs of force before it comes off, so If you pull up with that much you no longer have 130 lbs of normal force, but 230. Making your wheels much much harder to slip, so if you lock those down or have an uber drive train you are immobile. using the suction cup as a traction device does not work, use it to increase your normal force. I wonder if some teams still have time to use that advice? probably not unless they've already implemented it. Which I bet some teams have.
I saw one KOH bot with giant wings with sticky stuff on the bottom, the idea being to unfold and put weight only on that, but the only time I saw them in action the never managed to get out of the alley. I was kinda sad.
