The Circulator

“So basically, I tried to do it with the big motors, and it didn’t work — it didn’t fit — and so I tried to do it another way with the large motors, so then I had the idea of these two small motors, and I checked to see if I could put it anywhere else . . .

It goes in circles because it’s not even support on both sides.”

Rear-steered front-wheel drive buggy

This buggy uses a medium motor to drive the front wheels, and a medium motor to steer the rear wheels. The rear-wheel steering concept did not work well in practice. It was easy to program the rear axle to turn and then return to where it had started, but the friction of the tires would prevent this from happening.
