I haven't built one, but I've read write-ups on Instructables that might help. Here's one:

I also found this write-up at let's make robots:

If you want to control speed you'll need something that generates PWM signals.

Which normally involves a microcontroller.

I'm a fan of Microchip, but lots of other different microcontrollers, such as the Arduino, which seems to be quite popular on this website and many others will do a similar job.
I hope this helps.
