Abstract：Automated Library System Mobile Robot using A-Star Algorithms Currentlylibraries have realized many aspects of information technology such as book purchasesbook collectionsRFIDdatabases and other technologies that improve library management and service levelsOne of the technologies used is library robotsLibrary AutomationCan improve the level of library automationespecially in book returns and organizationUsing robotics technology to improve library management and servicesSpecificallyit mentions an automated mobile robot system that can automatically organize books on shelvessolving the problem of people failing to return books to their proper placesThis system uses RFID to identify book titles and uses the A-Star algorithm to guide robot movementThe A-Star algorithm is used to calculate the shortest path for the robot to find the shelf locationshortening the time it takes for the robot to return books to the shelves
