It's been a while since I last was there, took me a while to find again and
the site has signs of having been abandoned, but http://brickbots.com had
some on-line competitions a year or two ago, one of which was an inverted
pendulum. See http://brickbots.com/pastview.asp?cid=24 for details on that one.
I think it's a pretty tricky problem, especially if you limit yourself to
NQC and standard LEGO sensors. But with some custom sensors, and especially
if you use legOS, you should be able to do it. Steve Hassenplug's Legway is
a good example, if you haven't seen it yet. It uses EOPD's from
www.hitechnic.com and legOS.
