I'm very skeptical about the cd drive motors working that big of a robot...
I'm all for it if you guys can provide me a little guidance. How would I gear up a cd drive motor?

Don't be too skeptical. ONE can drive an 8-inch, 3-wheel Arduino-controlled robot. http://www.youtube.com/user/SDSMTMec...28/hG9tZ9O60dA

How do I know it was a CD drive motor? I'm one of the guys who took a CD drive apart, raided the motors, and wound up using it for the robot drive.

Now, when you dig up that R/C car, raid the gearbox. The more R/C cars, the more gearboxes. Then you can tweak the powering/gearing to suit your motors.
