I have attached the original message to this in case it should get
separated. My question is about stategy. The idea I'm thinking about are
arms that swing down from the main body of the robot at about an angle of
120 degrees, 60 degrees on both side of center. Now what I want to happen
is that the opponent gets trapped between these arms. If the opponent
swerves to the side on a flanking manuever, it would push against an arm
and swivel my robot around so that my robot is still pushing square on.
 
I believe that the arms are legitimate if they deploy from the 20cm square
area after the contest begins. Since there is no height limitation, I
imagine the arms pivoting down with gravity as soon as the contest starts.
 
My questions are: 
Is this a workable approach? 

Does anyone have any
experience using this technique?
 
If the arms touch outside the Duomo, 
has the robot lost?

What is the best wheel material 
for maximum friction?
