This looks similar to the Reading 'Griimblebot' which has ultrasonic sensor out on a single 'wing' measuring the distance from the ground.

It uses the more traditional wheel design instead of a moving pendulum to adjust CoG.

DJ did an Arduino self-balancing robot design over on Element14 Presents a while back:

not sure if any of his Arduino feedback loop control code may help. He also used a primitive balance bar arrangement to help balance the robot initially to a more stable pose. Could be an alternative way to balance if motorized, a bit like a tightrope walker's balance bar. (Extra points if you stick a wheel on it and get it to cross a rope)

cool idea. Could help to use a little trig for adjusting the weight position by the angle arm of the servo, essentially open loop torque at the balance point of the free body diagram.

I like it, sort of like a dog using its tail to balance.
