Robot Classifications

There are different ways of "kicking". Of course, when they say kick, people right away think of how a human would kick, which was demonstrated on Today's presentation.
Our ideas of output system, would be securing the soccer ball against a piston, and then when time is right, the piston pushes the ball straight into the goal post. We just thought of this idea today, it is definitely much more sophisticated than this.

We had slightly considered of going defense, but what if our robot is the only defensive robot on the team?
I am sure it would be very hard for the our robot to defend two goal posts to prevent 3 robots scoring...
Speaking of that, I don't recall reading anything about this in the rules; is it legal to have all 3 robots that are on the same team to be on the same segment of the field?
By segment, I meant such as end zone, or mid-field, or scoring-zone
