- Check out anything by Marc Raibert (e.g, Legged Robots that Balance, MIT Press,
- 1986, or CMU reports CMU-RI-TR-83-20, CMU-LL-4-1985). The machine in question
- used an inertial reference (gyroscope) to sense up. I seem to recall he had
- problems with keeping bearings in the gyros due to impact loading (falling
- down?)
