Step 1: Build a 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:
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).
