[Al Skierkiewicz]

<R12> Once the match has started, the ROBOT may assume a PLAYING CONFIGURATION that exceeds the size dimensions specified in Rule <R07>. While outside of its HOME ZONE, a ROBOT may expand up to a maximum width of 72 inches and depth of 72 inches. While entirely inside of its own HOME ZONE, there is no limit to the maximum width or depth of the ROBOT, as long as it remains entirely within the HOME ZONE. There are no height limits for a ROBOT in its PLAYING CONFIGURATION at any time after the start of the match (other than those naturally created by the ceiling height of the competition venue).

So for the record, prior to match start, a robot must be able to fit, unconstrained by the inspection box, in a 28 x 38 footprint with a predetermined height class of 48, 60 or 72 inches high. After match start and outside the home zone, your robot may expand to 72 x 72 inches with a height only limited by the ceiling height of the venue.
