Here's another cooperation idea.

The trickiest part of the climb is leaving zone 0 before touching the zone 2 bar. If you could sit on the floor and reach up to the zone 2 bar (touching zone 1 bar first, of course), inch worming up to the top isn't too hard.

So, robot A deploys a tarp from a roll and tows the tarp under the lowest bar, spreading it out to cover the ground. The tarp could be pretty big and not violate the 54" diameter rule. Robot B drives onto the tarp, thus leaving contact with zone 0, and inchworms up the pyramid, from bar to bar.

Robot A then reels in the tarp and hangs for ten points. Much less coordination between the two robots.
