Abstract：Mobile Robot Capable of Crossing Floors for Library Management Abstract-In order to reduce the labor and material of library management and contribute to the development of unmanned libraryan intelligent mobile robot for library management is proposedThe robot consists of a mobile platforma three-DOF rise-and-fall robotic arm and a multi-source image recognition information fusion systemBesides recognizing data and position of the bookthe robot is also able to conduct book grasp and shelving in order taskTo adapt to the existing library environment and enlarge its move areaan efficient autonomous elevator button recognition system based on neural networks is designedwhich enables the mobile robot span floors by elevatorCombined with visual recognition technologythe mobile robot has functions of autonomous navigation and obstacle avoidanceThere is also a data monitoring center and graphical user interface corresponding to the mobile robotwhich is developed to simplify the operation instructionsThe effectiveness of the proposed research is examined by simulation and experimentsThe innovation of the robot is that it can complete shelving book task on the premise of adapting present library to the most extentLibrary AutomationRobots can automatically complete the task of launching booksConsulting ServiceSimplify the operating instructions through data monitoring center and graphic user interfaceCollection ClassificationRobots can identify the data and location of books and classify them correctlyInstificational CollectionRobotics can move across floors to manage the collections of the entire libraryThe study proposes a smart mobile robot for library managedThe robot can identify the data and location of the bookthe scratching and the task of implementing the bookIn addition to theseit also has an independent elevator button recognition system based on neural networksas well as independent navigation and obstacles from visual recognition technologyIn additionthere is a data monitoring center and a graphical user interface corresponding to the mobile robot
