I know that's a common and plausible definition, but I don't think it's necessarily obvious or universal. The flop-bots and unfolding robots of yore are great thought exercises. Which side is really "up"?

FIRST should ask teams to designate a co-ordinate system relative to some component (e.g. with a sticker).1 All robot-relative restrictions should be measured with respect to that. Alternatively, starting/inspection configuration can be defined, and robot-relativity defined in relation to that.

Failing that, robot-relativity is ambiguous.

1 Don't use the frame perimeter. It's a trap. The definition allows for skew polygons and planar polygons not parallel to the floor.
