I looked at this chassis a few years ago. This one is a version based on 
one from Coroware. I mocked up a version using 1/2" PVC pipe to see how 
it worked. I was thinking of building a larger version if it worked but 
then got working on the NASA SRR.

The body mounts on a rod that connects the two rocker bogies. It is kept 
horizontal by the pivot arm at the rear. It is all passive. An 
interesting piece of engineering.
