4 wheels v. 6 Wheels

This is a popular design choice for robots. Last year for the 2013 game, Team 935 had a wheel drop. I want to say the final drop height was less than 1/8" (I'll check when I go over today and subsequently edit this post).

I remember a lot of problems when our robot came to a sudden stop while testing with a 1/8" drop. It would rock to rest on the two front or back wheels, depending on which direction the robot was going when it stopped. This would cause the Frisbee launch angle to lower -- or rise -- causing us to incorporate an angle of launch error to our shooting calculations. Just something you should pay attention to. Not having a drop on a six wheel is counterproductive to its design intent however. Again, I'll update when I run in today.
