Hi Tobbe,
I think four legs would be enough: build it so the legs on a given side are 180
degrees out of phase.
To turn, run only one side with the other side stopped so both legs are touching
the ground.
Driving in a strait line can be achieved in two ways: synchronize the two sides,
so they are 90 degrees out of phase or drive each side alernatively for one
turn...
Now we have to build it to find out! I guess that what rainy weekends were
invented for...
Greetings,
David
