video on last step.
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).
Step 2: Hardware(1): Stuff You'll Need
= two 24 volt wheelchair motors I had bought a while ago (to make a bot for the battlebots tv show, didn't happen) (from Ebay)
= two victor 883 24volt motor speed controllers (from ebay, originally sold by IFI robotics)
four 12v 5ah batteries (two in series for each motor) (from allelectronics.com)
= two planks of wood stolen from a contruction site
= two 10 foot pieces of EMT electrical conduit (from Lowes)
= a conduit bending tool (Lowes)
= bicycle inner tubes (go to a local bike shop and ask for popped tubes from the trash)
= u bolts, screws, locking nuts, locking washers, a ratchet wrench, hack saw, power drill
= friction feet thingees (you slide them onto table legs for friction) (from a local hardware store)
