Here is a different idea: what if your clamp were to clamp onto the bar and the robot were to spin sideways, in the plane of the pyramid's face? If the clamp were several inches wide and had a soft grippy foam surface, it might not spin around The axis but lift the robot into the air, kind of like what team 33 did in 2010 breakaway.

We did some concept packaging of this idea. We struggled with the robot package running into the pyramid and getting the second clamp on the second bar before moving on to other ideas.... Just want to help you avoid or design around the issues we saw if you go this way.
