Abstract：Development of a self-navigating algorithm for library book finder robot In this paper a self-navigating library robot is presented that goes to the required book shelf as a human would do and does not need to follow any line or fixed pathTo achieve this performance a self-navigating algorithm is developedThe library is co Library AutomationThis robot is designed for library automationused for automatic navigation to specific bookshelvesRetrieval and IndexingThrough autonomous navigation algorithmsthe robot can accurately navigate to the designated bookshelf locationthus assisting in book retrievalDiscusses an autonomous navigation library robot that can travel to the required bookshelf like a human without following any lines or fixed pathsTo achieve this performancean autonomous navigation algorithm was developedThe library is viewed as a 2D array of bookshelvesThe robot uses five ultrasonic sensors to measure the distance to surrounding objectsThese measured distances are essential for achieving all necessary functionalitiessuch as calculating the robots current row and column positionhelping the robot move in a straight lineand making accurate turnsUsing the developed algorithmthe robot works perfectly and shows satisfactory resultsindicating that the developed algorithm is effective
