Teddy,
The servo is a device that is used in RC cars and airplanes. It is a positional device that can be controlled via PWM signals to turn to a certain angle. It is not capable of turning a full 360 degrees but can control other items like the pan and tilt of the camera which do not require a full 360 degrees of motion.

Japper,
I am afraid they might not be powerful enough for your application but you should try and see if you could give them some mechanical advantage.
