The working principle of an ultrasonic sensor is simple and use high-frequency sound waves that are evaluated when the sensor received back the waves. To determine the distance between the robot and object, the sensor measure the elapsed time between sending and receiving the waves.

When using Multiple Ultrasonic (Sonar) Sensors together, you need to configure the Sensors to use ‘Single Shot Mode’, so only ONE Sensor is taking a measurement at any time. If you have all the Ultrasonic Sensors on at once they interfere with each other and give incorrect readings. To get around these issues, you need to take advantage of the LEGO Sonar Sensor’s Mode 1: Single Shot Mode.

If you wish to use Multiple Ultrasonic Sensors on your NXT Robot, you need to program them so only ONE Sensor is taking a measurement at any time. If you have all the Ultrasonic Sensors on at once they interfere with each other and give incorrect readings. To get around this you need to take advantage of the Sensors Mode 3: Event Capture Mode.
