In the future, social robots will permeate our\ndaily life. An autonomous robot that has to move among\ndifferent buildings needs to manage huge amount of data, as\na consequence it is clear that the configuration of the navigation\nsystem becomes hard to manage. This paper presents\na system, based on a cloud robotics paradigm, conceived\nto allow autonomous robots to navigate in indoor environment,\nwhich are not known a priori. The environment is\ndivided into sub-maps and all the necessary information and\nthe topological representation of the world, are stored into a\nremote cloud infrastructure. By means of specific environmental\ntags, composed of a set of ARTags and QR codes,\nthe robot gets the access to the cloud service and it is able to\nupdate its navigation configuration in a dynamic and automatic\nway. Experiments have been conducted in order to\nchoose an appropriate marker dimension and to demonstrate\nthe feasibility of the proposed procedure.
