| Abstract: | This paper introduces a kind of ultrasonic transducer which emits the sound wave to the air in the style of flexuous vibration and is fit to be used in the system for detecting and sensing the obstacles. The transducer with a simple structure is easy to be made and can produce strong ultrasonic waves in the air with a good directional character. |
