Hello. Can you give us some more information about your project? What parts are us using? How are your motors currently connected. What is working and what isn't.

I'm supposing that you are using a microcontroller for the robot. Now ,the most common method for speed control of DC motors is by PWM (Pulse Width Modulation).
heres a good tutorial about PWM http://www.societyofrobots.com/member_tutorials/node/228
'crazy' is the new hype! =)
