Hmm, now that you mention it, it is interesting. Orthogonal just means it's perpendicular to the two other vectors, if you made a robot that was say a parallelpipid but the only issue I see is that it has to be self supporting when it's being measured.

It was also in team update #1 if anyone wants to quick reference it.

Fake edit: Rereading the section, the box right after it says "Dimension 3 (vertical): 60 inches" this kinda gives up the possibility of a half flop robot.

Basically, the 28", 38", and 60" are all orthogonal dimensions with the 60" being a normal vector to the playing surface.
