Aiming at the problem of "difficult to put books on shelves" in the current library management, an intelligent book robot and its method of handling, sorting and loading are developed. It can autonomously locate, move, and avoid obstacles, and plan the path after obtaining the position of the book, and then pick up and transport the books, and place them on the bookshelf position. A new shelf device is created to grab stably most of the books and push them into the bookshelf. Its two-stage flexible expansion plate is developed to effectively expand the gap between books and have a high degree of tolerance. Mecanum wheels are used in the motion module, and the gray-scale sensor array are installed under the chassis in order to control effectively the posture of the car body. Book position locating is implemented by the visual recognition module with simultaneously recognizing multiple QR codes on the book spine. The results show that the rates of recognition and the completion of successful handling and loading are quite high.
