I believe we were called for posessing two balls at kettering,due to a wide roller. Sometime after that match the team proved to the head ref that the robot could only posess one ball at a time by putting a piece of paper under the ball and driving around practice field. The paper stayed under the ball and the ball stayed with the robot. This was done on a flat carpet, but i thought the question of this continues contact over those pesky half inch bumps and even up scoring ramp was answered in a q&a. Now if a robot just backs up and applies brakes and the ball comes up off the carpet, that sounds like a penalty.
