Visions of ubiquitous robotics and ambient intelligence involve distributing information, knowledge, computation over a wide range of servers and data storage devices located all over the world, and integrating tiny microprocessors, actuators, and sensors into everyday objects as well in order to make them smart. In this paper, we introduce our ongoing research effort aimed at realizing ubiquitous robots in an information structured space. For this, a ubiquitous space and ambient intelligent systems for a librarian robot are introduced and the RFID technology based approach for these systems is described.

This study attempted to propose various application and function improvement plans by analyzing robots operated in the libraries. Thus, the types and functions of robots operated by 16 domestic and foreign libraries were examined. Most of them were used for Librarian Assistance (Book Inventory, Book Delivery, Etc.) and User Service (Facility Guide, Search Aids, Etc.). Besides, the introduction of robots in the National Library of Korea (NLK) and their functional limitations were analyzed. As a result, this study presented the need to develop additional functions for the robot, develop quarantine and security robots, the need for a national-level policy for robot diffusion, and build a robot ecosystem.

In this paper, we propose a method for verifying the location of the books in working order to enhance the effiency of library management. On open libraries, occasionally people relocate the book by mistake or intention after reading one. In this occasion, the book is assorted as a lost property and cannot be lended to others, even though it is still in the library. To solve this problem, the system we propose takes an image of the book selves by a mobile robot and extracts the classifying information of the book. After comparison between current location of the book and assigned location of the library database, information of the mislocated books is notified to the librarian.

Among the numerous duties of a librarian in a library, the work of arranging books is a job that the librarian has to do one by one. Thus, the cost of labor and time is large. In order to solve this problem, the interest in book-arranging robots based on artificial intelligence has recently increased. In this paper, we propose the K-ACO algorithm, which is the shortest path algorithm for multi-stops that can be applied to the library book arrangement robots. The proposed K-ACO algorithm assumes multiple robots rather than one robot. In addition, the K-ACO improves the ANT algorithm to create K clusters and provides the shortest path for each cluster. In this paper, the performance analysis of the proposed algorithm was carried out from the perspective of book arrangement time. The proposed algorithm, the K-ACO algorithm, was applied to a university library and compared with the current book arrangement algorithm. Through the simulation, we found that the proposed algorithm can allocate fairly, without biasing the work of arranging books, and ultimately significantly reduce the time to complete the entire work. Through the results of this study, we expect to improve quality services in the library by reducing the labor and time costs required for arranging books.
