Abstract:The amount of books has been one of the important indexes for the level of library. While the daily management work of books such as how to classify and place books has aggravate the burden of the librarian. The rapid development of mobile-robot technology and multi-Agent give a new possible method to solve this problem. Therefore, this paper provides a move-robot model based on multi-Agent technology, which can recognize, classify and placed books automatically, and navigate the walk route by improved BUG algorithm which can complete the classified and arranged work quickly and correctly. This model can simplify the manual work and lighten heavy and repeated labor.
