Usage of the reflected infrared sensor in automatic guiding car

摘要

This article introduces the design and execution of auto-searching for track by usage of the reflected infrared sensor on the auto -guided car. The auto-searching for track is on the base of the AGV-auto-gu i ded vehicle system. It makes the car discern the routs, judge and evade the obs t acles automatically. So the car can choose the right routes. In the experiment we t ake use of the guiding wire whose color distinguishes from the background to gui de the car and the inflected infrared sensor to discern the guiding wire and obs tacles. The AT89C2051 Single Chip Microcomputer is used for the control core in this system, and the one-way PWM direct current electromotor for the motive fo rce or power system. This technology could serve to driverless mobile, robot fa ctory, warehouse, service robot and etc.
