This was me.

You can check out a very crude page I made at:

http://wollongong.apana.org.au/~ben/walker/

This was a very crude walker as well - it could carry only about 10 grams -
probably the weight of the electronics alone. But it did walk, and it
walked well. You didn't have to worry about center of balance, or anything
like that. You did, however, have to use a tether for power.
