Playing configurations are allowed, and are allowed to be greater than starting configurations. It is only that all playing configurations must remain within a 28x38x60 box.

So if you had a 28x28" robot base as your starting configuration, you could extend a mechanism 10" to the front of your robot... do whatever it had to do, retract it, then extend a mechanism 10" from the back of your robot.

THEN you could retract the mechanism at the back, and extend 10" to the left, etc. So long as the robot would, at all times, still fit in the sizing box.

R18D specifies that the trailer hitch must be located on the outer edge of the robot. I am unsure of what constitutes the "outer edge" of a "U" shaped robot.

I am sure GDC will clarifly this one on the Q&A very quickly if you ask.
