More to the point, can a frame damage the carpet?

It's also not terribly difficult to put some plastic on the bottom of a metal frame using countersunk screws or appropriate adhesive.


To answer the original question: If you have designed your robot to play the game in such a way that you do not need to move, I would say that you have satisfied the rules. (I would like to note that I have seen a wheelless robot take the field before, but it's been several years and a slight rule change on the definition of robot since that happened.)
