That's pretty cute.
Are there two independent motors in it? Do you know how much current they draw (stall current).

I am using this motor driver: http://www.sparkfun.com/commerce/product_info.php?products_id=9457 (http://www.sparkfun.com/commerce/product_info.php?products_id=9457)
Very small and works well (Pololu also sells it). It shouldn't be difficult to control it from an arduino nano.

Have fun and keep us posted.

yes it has 2 motors.  I have no idea about them because it came from a erector brand spykee minivox robot thingy.  I dont think im really going to start working on it untill i finish my current robot that i have to do for school

Are you tied to using a nano?

If not, there is a standard "motor shield" for the Arduino Duemilanove which should easily drive your motors (1 Amp continuous, 2 Amps peak) . These are widely available in kit form (great if you want to make any mods) and fully assembled.

More info on the shield can be found at: http://blushingboy.net/p/motorShieldV3/ (http://blushingboy.net/p/motorShieldV3/)

i kinda wanted to use a nano because it would fit perfectly on the little bread board on top
