I believe the OP is asking using SERVOs not DC motors. Hobby type servos have all the motor drive circuits inside so do not need a separate motor controller.
All that is needed is to apply power and a servo control pulse train to command the servo to a position.
This can be done from almost any uController.
Do check out the Axon processor and WebBotLib as these are capable of controlling a good number of servos. There have been a few threads about this so search the forum for more info.
