If I remember the usual rules correctly, a certain amount of what may be termed 'aggressive play' is permitted, as long as the intent is to prevent the other robot from scoring or to enable your robot to score points. This does include pinning, but only for a limited number of seconds. Pushing an opposing robot to keep it from scoring points is, likewise permitted. Wanton destruction of another robot is not permitted, which includes beating up on a robot when it's down. Pushing a downed robot out of your way so you could score points is something that could be subject to a referee's judgment.
