DESIGN AND DEVELOPMENT OF LIBRARY MANAGEMENT ROBOT BY USING E-YANTRA

MECHANICAL ENGINEERING

Library robot is an assistant system used to assist the user who wants to search, locate and collect the required book in the library. The request of the user book Bar Code ID scan though bar code reader is processed in the computer based pre programmed system, which is stored in Arduino Uno Atmega328 Microcontroller have to informed about the particular shelf or location is classify in such manner odd number for upper and even number for lower shelf of book rack, It also carried bar code Id for each Book. Using this information, the robot has its movement towards the informed location and performs barcode scanning across the shelf to find the requested book. The robot with its lead screw is positioning vertical distance & sliding arm through rack and pinion mechanism can scan the books in a particular shelf and barcode matching is done in the microcontroller based system. The robot exerts force to pick the book through gripper, which is found to be matched by the scanning system and placed book in issuing counter. Library management robot is a line follower robot to follow a black line path, already predetermined by the user. The system with its integrated automatic object recognition and force feedback make the robot to deliver the book as soon as possible by minimizing the search time of the user.
