Take precise steps! The Servo Motor has a built-in rotation sensor that measures speed and distance, and reports back to the NXT Intelligent Brick (sold separately.) This allows for precise steps and complete motor control within one degree of accuracy! Several motors can be aligned to drive at the same speed.

Detect light intensity! The Light Sensor assists in helping your robot to “see.” Using the NXT Brick (sold separately), it enables your robot to distinguish between light and dark, as well as determine the light intensity in a room or the light intensity of different colors.

Your robot’s “ears!” Using the NXT Brick (sold separately), the Sound Sensor allows your LEGO® MINDSTORMS® NXT robot to hear! The Sound Sensor is able to measure noise levels in both dB (decibels) and dBA (frequencies around 3¿6 kHz where the human ear is most sensitive), as well as recognize sound patterns and identify tone differences.
