I regret to say that what Jennifer describes may have been an incorrect
ruling on the Craters Crossing Mission.  The Crossing Equipment for M04 may
be any item of team Equipment, and does not have to include the Robot.

I understand that there was a lack of clarity of exactly what was included
in "crossing equipment" until update U06 came out this week.  Actually,
there was a team last weekend whose crossing attempt I did not allow, but
would have allowed this weekend after the update, and many teams at today's
tournament that would have had trouble convincing me last weekend that they
had an appropriate interpretation.

The referee might have thought that since the Robot caused the projectile
to move, and might have been over the Craters or even between the Towers
when it was released, that the Robot needed to be included as part of the
crossing equipment.  Depending on the position of the Robot, that's what I
would have said previously.  U06 says explicitly that "It does not matter
if a separate object throws, pulls, pushes, carries, places, or paves the
way for the actual crossing equipment, as that would be a separate object
and not considered part of the crossing equipment."  For example, a Robot
that throws a projectile across the Gate would not be a part of the
Crossing Equipment.

The best thing that your teams can do is to be able to point out the exact
text in the Updates, Missions, or Rules that show why they have the
interpretation that they do.  That's how they might be able to change the
Referee's mind, or get Benefit of the Doubt applied.  They may not be
successful, but they will have done everything that they can to support
their interpretation.
