I think I would rule as follows:
- A robot that extends into their opponents side of the field, either through or over the fence, is not in and of itself in violation.
- A robot that extends into their opponents side of the field and in doing so restricts the movement of an opposing robot to a particular part of its side of the might be in violation, if
a) the opposing robot actually attempts to move out of the space to which it is restricted and
b) the restricted space is a relatively small potion of the opposing side of the field (1/2 or less). Therefore
a robot that extended a fence around stars in their low scoring zone would not be necessarily in
violation assuming that the fence did not restrict the opposing robots from moving around most of
their side of the field.
c) it would be a violation if the extended robot extended completely across their scoring zone, thereby
dividing the field into two separate regions.
I hope this makes sense. This is what I have gotten to based on the Q&As so far.
