Line following robot for library inventory management system

This paper demonstrates the application of Line Following Robot (LFR) for library inventory management system (LIMS). A line following robot is designed using sensor operated motors to keep track the line path predetermined for library book shelf arrangements. The robot carries a barcode reader which collects the barcode data from the books arranged in a vertical manner and compares the decoded barcode data with the search input. If the robot reaches the book which is to be found out, then the robot gives location of the book to the librarian or the person visiting the library, in which the robot is used for searching purpose. In case of any hindrance faced by the robot when it does the searching process, the robot halts and sends an alarm. Misplaced books can be rearranged using the pre-programmed data in the robot which helps to maintain the books in an order. This helps and simplifies the job of arranging the books and also reduces the manual routine work done by the library staff.
