Introduction to motors
Servo Motors
Motors that transform electrical power into mechanical power are known as Servo Motors.
Built-in Rotation Sensor
The Interactive Servo Motors have a built-in Rotation Sensor. The rotational feedback allows the NXT to control movements very precisely. The built-in Rotation Sensor measures the motor rotations in degrees (accuracy of +/- one degree) or full rotations. One rotation is 360 degrees, so if you set the motor to turn 180 degrees, the hub will make half a turn.
