An Arduino of your choice, a motor shield (keep in mind how many motors you will be running), and some way to send and receive commands.

An UNO is what everyone starts with, but depending on how many motors you will be controlling, and whether or not you need to control speed, you [u]may[/u] need a mega. However, if you a good motor shield, then a UNO can control up to 6 motors with speed control.
