System Design and Experimental Research of Mobile Robot for Library Management Based on Robot Operating System

A mobile robot for library management based on robot operating system (ROS) is designed in this paper, aiming at alleviating the pressure of library management and enhancing the readers’experience. This robot can scan returned books, store them on its built-in shelf and autonomously navigate to the corresponding book bins, where the staff complete the shelving, simple classification and transportation. The mechanical system design of the robot is introduced and the dimensions are optimized through finite element analysis first. The hardware and program design of the robot’s control system adopts differential algorithms, motion model algorithms and dynamic window algorithms. The results of real-world experiments show that the robot can effectively complete the tasks of automatic book retrieval and navigation, which has significantly improved the efficiency of library management.
