A little Confusing
Al,
I'm assuming your response was regarding my calculations. My last post was only to clear up what many already know. If you design your robot to put out 100lbs of force per wheel and your coeficient of friction between your wheels and the floor is not high enough; then you will be wasting output power, becasue your wheels will spin. I also noticed my 2 posts were confusing if read one after another. The friction I was talking about in my first long post is drivetrain friction (as you mentioned, too) and the friction in my last post was friction between the carpet and wheels which provides tractive force (or the force to propel). Bottom line:
A drag racer can have all the output torque in the World, but it does no good on ice.
