Yeah, the Basic Miller design didn't lend itself to
turning as easily as the uni-bug type did. Can't
think of any other orientations.

No Photodiodes, I used Photoresistors. I crudly added
them to the resistors of the nuerons that controlled
the back legs. Similar to a Potentiometer.
I only shorten and lengthen the back legs, I try and
keep the front legs rotating at a constant length, and
speed.

The Andrew Miller method of turning the front motor
would work good, but I have yet to design a timer
circuit for this.

Everything I say can mean one of two things...If something I say makes you mad....I meant it the other way.
