<R15>Flag Holder

[FRC111]

1) R15 says that the flag holder must be permanently mounted to the "central mass" of the robot. Can I assume central mass is any part that does not move or is it any structure that starts the match within the allowed starting box even if it might move and tilt the flag?

2) R15 say that arms and appendages may "temporarily intrude" above the flag. Does this mean that you can start the match within the legal starting box but with an appendage that is well above the flag as long as it is intended to move sometime during the match? My concern is the word "temprorary" since this condition may exist for the majority of the match during scoring when appendages may always be above the central mass of the robot.

During the match the flag must remain approximately vertical. If it is mounted to a body part that tilts significantly, then this is not an appropriate mounting point.

The intent of Rule <R15> is that during the majority of match play the flag is the tallest point on the robot, so that it may be easily seen and the alliance assignment of the robot may be easily determined. If an appendage or manipulator spends most of the match higher than the flag, then this is not a "temporary" condition. This would be considered a violation of Rule <R15>, and would need to be corrected before the robot would be allowed to play in another match.
