Intelligent mobile robots are expected to reach target locations while avoiding obstacles. However, there are many obstacles in our living space. Therefore, it is not easy to develop wheeled or legged robots that can avoid obstacles in such environments. One solution is a blimp robot. It can go over obstacles easily and does not need much driving force. Our final goal is to develop a blimp robot that flies freely in a three-dimensional space. As a preliminary step, in this paper, we present the experimental results and discussion of airship control technology using an image processing system and wind disturbance observer.
