G403       Limited AUTO opponent interaction. In AUTO, a ROBOT whose BUMPERS are completely across the BARGE ZONE (i.e. to the opposite side of the BARGE ZONE from its ROBOT STARTING LINE) may not contact an opponent ROBOT (either directly or transitively through a SCORING ELEMENT CONTROLLED by either ROBOT and regardless of who initiates contact).

G424       *Don’t tip or entangle. A ROBOT may not deliberately, attach to, tip, or entangle with an opponent ROBOT.

G425       *There’s a 3-count on PINS. A ROBOT may not PIN an opponent’s ROBOT for more than 3 seconds.

A PIN count ends once any of the following criteria below are met:

G426       *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.
