Abstract
Tele-operated mobile robots play an important role in observing active volcano areas in restricted areas. However, it is very difficult for current mobile robotic technology to traverse a whole path from unrestricted area to the destination in restricted area by itself. Therefore, we drew up a scenario in which an electronic rotary-wing UAV transported a small-sized mobile robot by air. Based on the scenario, we developed a prototype rotary-wing UAV and conducted some field experiments, in which the UAV carries a small robot. In this paper, firstly, we discuss changing factors in thrust of rotary wings in different altitude, then introduce the prototype UAV, and finally, report some field experiments and evaluations of them.
