That was my second choice.
Ok, three motors.
If it can be worked out, we COULD combine #1 and #3, right?
Leaving:
1) Function (walk/turn)
2) Direction (forward/backward/stop)
I assume both of these groups are controlled only by motors, and at no time are
they moved by pistons.
I still think walking sideways is cool, but optional.

Right.

looks good. But slow.
