G423      SOURCE/AMP ZONE protection. A ROBOT may not contact (either directly or transitively through a GAME PIECE CONTROLLED by either ROBOT and regardless of who initiates contact) an opponent ROBOT if any part of either ROBOT’S BUMPERS are in the opponent’s SOURCE ZONE or AMP ZONE.

G422      PODIUM protection. Prior to the last 20 seconds of a MATCH, a ROBOT may not contact (either directly or transitively through a GAME PIECE CONTROLLED by either ROBOT and regardless of who initiates contact) an opponent ROBOT whose BUMPERS are in contact with their PODIUM.

G405      Limited AUTO opponent interaction. In AUTO, a ROBOT whose BUMPERS are completely across the CENTER LINE (i.e. to the opposite side of the CENTER LINE from its ROBOT STARTING ZONE) may contact neither an opponent ROBOT nor a NOTE staged in the opponent’s WING (regardless of who initiates the contact).

G421      *Don’t collude with your partners to shut down major parts of game play. 2 or more ROBOTS that appear to a REFEREE to be working together may not isolate or close off any major element of MATCH play.
