Sensors provide feedback to a system telling it where it is or how it's doing. The NXT has several types of sensors designed specifically for it, and backward compatibility to the old RCX sensors. All the sensors are well documented by LEGO, but we'll provide additional characteristics and show the internal construction of the sensors.
The NXT comes with five types of sensors: Touch, Light, Sound, Ultrasonic, and Rotation. The NXT Rotation Sensor ...
