This is the robot I built to solve the Towers of Hanoi puzzle . It is made of 3 RC servos , balsa wood , lite plywood , servo tape , hot glue , 2 plastic gears , and a paper clip . The control computer is a Radio Shack project board with a Picaxe 08M . The servos are powered directly by 4 AA batteries .Two 1N4001 diodes are used to drop the voltage to 4.8V for the Picaxe . The Picaxe program is adapted from a basic program in the book "Artificial Intelligence Projects For The Commodore 64" by Timothy J. O'Malley published in 1985 . It uses 235 of the 256 available bytes in the 08M . The servos for the rotation and elevation are 15 years old , weak , and jittery so the positioning is not as accurate as it should be . It is shown solving the puzzle with 4 disks which takes 15 moves .
More information and the basic code can be found at http://letsmakerobots.com/node/26793
Fabulous work Bill! I built a similar one using a BASIC Stamp at youtube.com/watch?v=-Z8lTSX4PHs

Nice robot! How did you use the Picaxe to control the servos?
