If you are using servos, what is the motor shield for? Servos can be controlled directly with the Uno pins using the servo library. continuous-rotation-servos Note that I said "controlled" not powered. The servos need to be powered by an external supply capable of supplying the current required by the servos (likely around 1 amp per servo). A 4 AA cell pack will usually work.
