Abstract

The authors describe novel sensors for the follow-up control of an automatic guided vehicle (AGV). In the running control system, two kinds of novel acoustic sensors for detecting the angular difference between the direction of motion of the forward running vehicle and that of the following vehicle are examined. The operating characteristics of the novel acoustic sensors are presented. One sensor is a 40 kHz ultrasonic wave sensor, while the other is an audible range sensor operating at a frequency of 1 kHz
