Development of a self-navigating algorithm for library book finder robot

摘要

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 path. To achieve this performance a self-navigating algorithm is developed. The library is considered as a 2D array of book shelves. The robot uses 5 ultrasonic sensors to measure the distances of its surrounding objects. These measured distances are prerequisite of achieving all the necessary performances, such as calculating the current row-column positon of the robot, help the robot to move in a straight path, making an accurate turn etc. The robot works perfectly using the developed algorithm and shows satisfactory outcome which indicates the validity of the developed algorithm.
