I have always been curious how one of them would steer with the wheels on the front. I would think it would take a fair amount of braking on the appropriate track for turning. sort of like with duals on.
 
It would be interesting to see the details of that track drive set-up. Does the track have rollers or does it
just slide? Does the sprocket engage rollers or teeth? Back in my early days, I had a project to design
a sprocket that would internally drive a roller chain in a circular curved track. That was a really involved
job even with the early computers available back then. These guys must have used trial-and-error, or wear-it-in
techniques. The designer also really outdid himself with those pretty wheels.
