If you go into the corner, you are at risk of crossing 2 edges of the frame perimeter at the same time. See [G21] for the penalty this situation. This would bar any devices in the corners unless they go out one side and twist/extend into place.

Sorry to have taken so long Eric,

[G21]

Robots may extend one appendage up to 14 in. beyond a single edge of their frame perimeter at any time.

There is no specification of any direction that should be measured from nor any point on the frame. Therefore, I choose the one most
advantageous to my self. Without specifications, that is the most appropriate and also tends to be how inspectors do it [IMO, but I do understand that my O is not necessarily all that good]...

So far, I can find no update that references G21. I could be wrong, but I don't think so.

Additionally the following question and answer seem to me to bear this out:

Q. What is the width limit of an appendage? Can an appendage cross the line drawn as an extension of a perimeter edge that
is perpendicular to the base edge that the appendage is crossing? FRC0053 2012-01-15
A. There is no explicit width limit for a Robot appendage. Per Rule [R21], "Robots may extend one appendage up to 14 in. beyond
a single edge of their Frame Perimeter at any time."
