カオス超音波センサを用いた距離と横方向位置検出

Abstract

Compact and law cost supersonic sensor with relatively high accuracy in the short-ranges has used for sensor of the unmanned truck and robots. However, supersonic sensor may malfunction by sound noise in factories or by interference with another supersonic sensor. Because supersonic wave spreads, supersonic sensor would also detected object in lateral position. A new type supersonic sensor using one receiver and two transmitters can detect not only a distance between the object and sensor but also a lateral position. At a distance of 2.5m, this sensor can detect the lateral area of ±40cm.It is confirm that the sensor can measure a distance with average error of 4%.
