ACTUATORS

	AC Motors Motor which requires AC current.
	DC Motors Motor which requires DC current.
	Brushless Motors DC motor without the brushes. Better but more expensive than regular DC motors.
	How to Waterproof a Servo Learn how to waterproof a servo.
	Linear Motors Brushless motor with an X-Y plane actuation.
	Modify Servo Tutorial Modify your servo for 360+ degree continuous rotation.
	Servos Basic DC motor with built in feedback control. Affordable and easily available.
