G417      *Stay out of other ROBOTS. A ROBOT may not use a COMPONENT outside its FRAME PERIMETER (except its BUMPERS) to initiate contact with an opponent ROBOT inside the vertical projection of that opponent ROBOT’S FRAME PERIMETER.

Violation: FOUL.

For the purposes of this rule, “initiate contact” requires movement towards an opponent ROBOT.

In a collision, it’s possible for both ROBOTS to initiate contact.
