Agreed... This is fundamentally the exact same mechanism of "grasping" the sidewall as 118 used if the CG isn't over the bridge surface, like you said. The only solutions physics could allow for this Free Body Diagram (that I can think of) would involve either "gluing" yourself to the surface of the bridge or "grasping" the sidewall of the bridge similar to how 118 did.

I don't have that hard a time believing this one wasn't ruled illegal, though... This one looks to basically be sitting on the bridge. 118 looked to be hanging off the side. So much of how the GDC ends up ruling things is based off how the solution looks. If they see something they don't like, it seems like they then figure out how to rule it illegal... * sigh *

EDIT:
Wow, if that really is true about the robot being designed so it's CG is in the 8" on the bridge-side of the robot, that is simply incredible! Congratulations!

Even if it is illegal, I'd still say congratulations on accomplishing it - I would wish it (and 118's hanger) were legal!
