The principle of Ultrasonic transducer for distance ranging
Mobile robots use principle of ultrasonic transducer for distance,which the transmitter send an ultrasonic wave in a direction, and launch time at the same time to count on the time, ultrasonic distance measuring transducer in the air on the way to encounter obstacles or objects to return immediately ,When the receiver receives the reflected wave, it immediately stops counting. At this time, the timer counts the time when the ultrasonic wave travels back and forth from the robot to the obstacle, so that the high precision ultrasonic transducer for distance that the robot transmitter face the obstacle can be calculated.
