Wheelchair Wheels Don't Cut It? That's Not Always Bad.

We all do our best to design bots to play the game, and that always means attending to traction. We've had a lot of discussion, learning, and teaching on these boards about friction coefficients, normal forces, and surface shear.

But these robots do other things after the season, and some of those things have as much to do with FIRST's goals and its future as does playing the competition matches well. I'm specifically talking about the team students touring the bot around to local Elementary and Middle schools and putting on demos for the younger kids. Talk about a hit, and a heck of a recruiting tool.

These demos almost always happen in the school's gym, which almost always has a hardwood (basketball court) floor. Usually someone in the school is mighty particular about damaging or even marking that floor. So think about how you can design a competitive bot which makes its traction in a way that still lets it run on a court without damage, or about an alternate set of "demo wheels" for that purpose. Believe me the 6th grader taking a turn at the stick won't care if she can't shred 4x6's and get air.
