First, The _Prototype_:
Before you make a large, high power robot, it's good to make a smaller scale prototype. I made a simple walking robot using
= Brains: PIC16f877A,
= Actuators: two small geared pager motors (http://www.solarbotics.com/products/gm10/)
= Actuator Control: an L293 H-bridge,
= Body: I used one of those thin metal things that cover your unused card slots at the back of your PC.
= Fasteners: Everything was kept together by double sided tape and twist ties and some small screws from an old computer case.
Info on how to use the PIC and the L293 h bridge motor controller are covered in my previous instructables:
PIC: http://www.instructables.com/id/Intro-to-PIC-Microcontrollers/
H-Bridge: http://www.instructables.com/id/EHL7TR9A61ETVPKL4D/
--Notes--:
you can download the code I used (LWalker.bas).
The gears on the motors are important because they add torque (needed for a walking robot since it has lift its own weight).

The front motor is activated in any given direction, rapidly followed by the rear legs, rotating in the opposite direction. After that, both motors reverse, starting with the front motor.
