As such, I calculate that an object of negligible width can protrude (72√2)-38-14 = 49.8 inches from the front of a standard size robot. Is this consistent with our current interpretation? Does this make sense in the spirit of the rule?
I checked your math and you got it right. Then I considered the second case, in which the long side of the robot is perpendicular, rather than parallel, to the diagonal we're considering the arm to come out on. I did the math for that, and it seems that if your arm is coming out of the center of the wider side, its maximum length is actually 54.82", a gain of about 5". Maybe this helps someone.
