Our research is focused around idea of using sensor network and mobile robots cooperatively for solving various tasks. Moreover, sensor networks and mobile robots both benefit from such collaboration. One of the examples of such "symbiotic" approach is solution to the mobile robot navigation problem. The task is to detect the area requiring robot"s presence in the environment and then to guide the robot into that area. We propose solution to such problem and present results from real-world experiments conducted at Intel research facilities in Hillsboro, Oregon.
