Yeah, the center of gravity of the whole assembly is ABOVE the beam, so the
whole thing is by definition unstable. Weird. I didn't quite get it either.
Are we missing something?
My thinking is (and I built a quick model from LEGO) that we would use the same
concept, but upside-down. SO the CG would be below the beam, making it STABLE
and tilt less as the 'bots moved outwards.
Looking at their nice aluminum square extrusion beam, I was thinking about your
suggestion for the beam Iain.... if you come down to the next dinner, how about
bringing a short sample for show-n-tell? More uniform, smoother, and stiffer
than a 2x4, no? And metric too :)
