I can’t find this addressed in the rule book but just came back from a tournament where a robot removed a mobile goal from an opposing robot. The team had successfully loaded a mobile goal and the opposing team used a mechanism designed to tip mobile goals to pull it out of the intake. The mobile goal was not grasped or grappled. There were no cones on the mobile goal. Would this be allowed whether or not a mobile goal had cones on it?
Provided that <SG6> has not been violated (you clarified that it had not), there are no rules prohibiting this. However, teams attempting this strategy should be cognizant of a potential <G12> violations at the referee’s discretion, if the action damages, Entangles, or tips the offensive Robot.
