You are correct in that static friction is the only force pushing the robot. maybe slip is not the word I'm looking for. What do you call when the rollers spin, not the wheel itself. Slip of the ROLLERS is different than static friction being broken between the rubber and the carpet. When I use the term slip for the rollers I mean the rollers free spinning.
