Hey Paul, I hope it works too, The kids did a bunch of math and then ordered a specific rubber from McMaster Carr. A few sheets of it are here and to be honest it doesn't seam very sticky to me, but if I put any weight on the sheet it is relatively hard to slide across my counters. I'm hoping it is sticky enough, if not I hope we can find a way to find softer/stickier rubber in time.
We may have to go with a stinger or wheelie bar idea, and in I have an idea as to how we could maybe do it, I'll have to look at the cad drawings.
As for the room in the top of the robot, there is a bucket that goes there for dumping disks in the top of the tower.
Thanks for the advice, I'll share it with the kids!

What I believe Paul is getting at is that you can't rely on a tractive surface alone. No rubber from Mcmaster has a CoF of 1.7 on a smooth steel pole, coefficients between two objects must mechanically interlock for the coefficient to get above 1.0 and steel poles really don't offer much of anything to interlock with. Even Roughtop wheels against carpet are only 1.4 when brand new. Basically you need something actually attached/ reaching around the pole to keep the robot from sliding/falling down.. I would have your students begin brainstorming ways to do this so when the traction-only plan doesn't work out you have a plan B.
I really hope you can pull it off.
Good Luck, Bryan
