We have a plan to add scaling capability to our robot, using only:
* three zip ties
* one servo, and
* one special high frequency whistle.
The whistle is a new AM product that we are beta-testing. It summons Andy Baker. When he hears our call, Andy dons his cloak of invisibility, teleports to our opponent's courtyard, lifts our robot with his pinky, and levitates.
Then our robot uses the servo to attach a hook, made from three zip ties, to the climbing bar. Done.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
