I have been wondering how the word perimeter will be interpreted. I would like to know if you could build a u shape robot that the ball could go into the center as long as they did not invade over 3 inches in the robots actual perimeter. I was also wondering if they would interpret it a the larest square the robot can sit in.

I also would like ot know if you have wheels out side the frame do they count? any help would be very apprieciated!!! thanks
