This is known as a "reaction wheel". You should research if it will provide more turning capability than what you can already do with a standard wheeled drivetrain. If it will, then use it, but if it won't....

EDIT: Oh, typically you would use a reaction wheel horizontally, speeding it or slowing it rapidly to transfer the angular momentum to the robot chassis. What you propose is a simple gyroscope, which could also be effective.
