Raj,
There's a bit of confusion here. I believe the above quote actually came from
Steve Baker (posting only as Steve).
As Steve Baker pointed out, there is a difference between kinetic (sliding)
friction and static friction. (http://en.wikipedia.org/wiki/Friction) In the
past, I've spent time trying to identify the best approach for things like this
and LEGO sumo. It's difficult to find people who agree on what's best.
All the physics for this begin to get messy when you start talking about kinetic
friction, so, my suggestion is to do some testing yourself.
In my opinion, you want the wheels to go as fast as they can, without stalling
the motor. If two robots are pulling each other, I assume all wheels will be
sliding. That being the case, I'd want mine spinning as fast as possible.
