Remote surveillance is becoming increasingly important in Nuclear Safeguards. Different schemes can be devised depending on specific applications, differing in, for example, the presence or absence of front-end processing, the communication media, and the interactive capabilities. For some time the JRC has been working on the use of mobile robotics for the remote verification (for example, inventory and/or surveillance) of a pilot plant storage area. A mobile robot is equipped with two video cameras mounted on top of computer controlled pan-and-tilt units. The paper concentrates on two aspects of the project: (i) the description of the active vision system (TV camera, pan-and-tilt unit and motorised zoom and focus lens), its hardware and software architectures, and the human-computer interface that was developed; (ii) the use of ultrasonic data for computer aided navigation including obstacle detection and avoidance. The two aspects, though not directly related, cover two key elements for a remote surveillance system: the video surveillance equipment, and the system's ability to navigate safely in a remote environment.
