In response to the inefficient and complex traditional book sorting methods， especially the limitations of traditional book sorting equipment using CCD line scanning， an intelligent book self storage car has been designed. This storage car integrates ROS operating system， Movebase navigation framework， and YOLOv3 object detection technology， with the ability to identify empty shelves and place books by category to achieve automated book storage and placement services. Through on-site testing， it has been demonstrated that the storage vehicle is practical and efficient in scenarios such as libraries and home bookshelves. This study provides feasible technical solutions for improving book sorting methods and enhancing the performance of book sorting equipment， which has positive practical significance for book management and intelligent book sorting.
