If you need to control some motors wirelessly this Wireless Motor Controller project by PyroElectro might be just the thing to get you kickstarted. The project uses SN754410NE chip to drive the motor and a XBee module to make the project wireless.
“The purpose of this project is to build a system that can independently and wirelessly control two DC motors. To do this, the system will need 4 core components: an input system for the transmitter, a wireless transmitter, a wireless receiver, and a motor controller connected to the receiver.”
