Balacing a two wheel vehicle seems a art or magic for most people who are unfamiliar with 'Systems Control'.
Balacing is knowing how a process behaves. And react to it if the process is out of balance :) (Error is the tilt. then the process determends how to respond to it without making the vehicle tip over.)

Constructing a fun device like the 'model-t' out of it is an entire scope though... solving an equation is step 1,, building it up to a real device is step 500

I found that site a while back and was thoroughly impressed, he's done a self balancing unicycle now, if I remember correctly (although it only balances in the backwards/forwards sense, you still have to do the left/right stuff)

Four legs good, two legs bad, three legs stable.

Looks to me as if that is "only" the left right part, in other words it looks as though the centre of gravity is below the axle, so there's no "Segway" element to this project. Still very neat though..

Why not add an third wheel for stability? It wouldn't take up too much extra room, would it? (I'm assuming they didn't do that for space concerns. Or would it put too strain on the motors?)
