This paper presents a simplified architectural descrip-the sense that no special a priori knowledge by the people tion for the urban surveillance experiment under development within is to be required for the interaction with the robots. The the URUS project.surveillance application will be tested at the north campus The description contains two views in the computational viewpoint of Universidad Politecnica de Catalunya (see Figure 1 for a that are also applicable to other classes of network robotics problems. These are a functional layer through which the system has basis set of views) in a square area of approximately 100 meters operational capabilities, and a human layer that concentrates the long side length. Around 20 IP cameras are placed outside the systems related to human-robot interaction.buildings to cover most of the test area. These cameras provideKeywords: Networked Robots, Robot Control Architecture, the information for detecting emergency conditions, people Architectural Description activities, and robot localization, among other functionalities. The photos show a regular surface that poses no special
