The difference was like night and day in determining whether or not we could traverse the bump. Rubbing alcohol or isopropyl swabs found in most first aid kits do the trick very nicely and won't kill electronics if a drop is spilled on them.

Interesting, does this give more friction? I can't imagine much of a difference on a rough surface like carpet...

I know one of our rookies was having trouble with climbing the humps -- their mecanum wheels (AM 6") were covered with blackish gunk. They kept roughing them up with sandpaper between matches.

We didn't have the same problem, but we never actually left the middle zone throughout the FLR, so I'm not sure if it would have any big effect on ours. I have no idea where the blankish gunk came from, but they seemed to have more of it than we did.

What I find interesting, is at kickoff there always seems to be a sort of exasperated sigh when the game comes out especially this year. But now that seasons comes around I love how everyone cant wait. Every year i've been apart of it there some griping about the game for a while but then they start to love it. It's almost as if FIRST plans that. Other than the fact that it really is a low scoring game I like it as all other games. It may not be as extravagant but it is still just as fun to be apart of.

The black goo is very slippery on the carpet, so slippery that we were spinning the wheels under full acceleration from a dead stop. We had at solid film of it on our wheels before we discovered it. It's the gray 6" & 8" AM rollers, not the black ones that are exclusive to the old 8" AM mecanums.
