Library book locater
Abstract
This research is concerned about design and construction of mobile robot, Library Book Locater. The mobile robot is designed to locate the location of a book in a library bar code. This mobile robot reduces time taken to find a book in a library. The mobile robot is also designed to moves through line follower system. A barcode scanner build on mobile robot is use to scan bar code of the book. This project designed based of a control processing unit (CPU) that include a hard disc and a microchip AT89C2051 controller board placed on mobile car. The actuator of mobile robot consists of two DC motors. The mobile robot's motion is programmed loaded into the AT89C2051 microcontroller using software tools 8051 assembly language. A line follower was created which mobile robot moved to locate a book. Three light dependent resistor (LDR) sensors are building at mobile robot detected to move toward book rack. The frame robot is made mainly of aluminum bar.
