I’m not sure if I should ask this on the q and a but I was wondering if it is legal to push an opposing robot into their non protected goal zone to knock over a stack. SG3f only applies to the protected zone and your robot would never be contacting the scored cubes (SG3b).
The main issue here is the fact that the rule book specifically states that it is illegal to force another object to do something that would otherwise be illegal for your robot to do, meaning that it is illegal to force your opponent to knock over their own cubes, and the fault of the fallen stack would be on you. This same principle is true for the auton line, it is illegal to intentionally use a cube or other object to disrupt the opponents auton as it would be illegal for your robot to perform the same action.
Does the rule say that you can’t force an opponent to do something that would be illegal for you? my interpretation was that you can’t force an opponent to break a rule.
Stay away from your opponent’s protected areas. Robots may not intentionally or accidentally, directly or indirectly, perform the following actions: B Contact any Scored Cubes in either of opposing Alliance’s Goal Zones
In the official Q&A response it says (bold added for emphasis):
Therefore, a Robot which pushes an opponent into the opponent’s own Protected Zone or Goal Zone would be subject to the full extent of SG3.
