RC servo modification for continuous rotation

A standard hobby RC servo motor is designed to rotate through only 180 degrees. They are most often used in RC applications (like steering). The servo motor controlling is done with servo control pulses (1-2 ms pulse at around 50 Hz rate). More details on the control signals can be found at Servo protocol web
