It depends on your design. The chassis that I designed didn't rock back and forth at all. The center wheels were lowered 1/8th of an inch and the wheels were modified andymark kit wheel. I used roughtop for my design. Roughtop has a coefficient of friction of 1.3 (I know many of you know this, but there are others who doesn't).

Also, I saw a similar 6wd when I went over to team 1251's home. They are using 4 inch wheels and middle wheels were dropped .25". I didn't see any rocking on their bot, and even if there was any it was very minimal. They used wedgetop. The coefficient of friction for wedgetop is 1.2. The designer of the robot made a statement as follows, "We lowered the middle wheels .25" but the wedgetop compresses about 1/8" so in reality, it is only 1/8" lowered."

I have got a calculus exam Monday morning that I need to study for. I know there are few posts here that asks how to design a 6wd, or how it works (similar to those questions). If you got questions and would like to have a discussion, you have got my aim screen name or email in my profile. Feel free message me.
