The University of Electro-Communications

A wide variety of research projects on unmanned aerial vehicles (UAVs), which can be expected to be used from the air in the event of a disaster, have been paid a lot of attention in recent years. Prof. Kazuo Tanaka and his team, Department of Mechanical and Intelligent Systems Engineering, Graduate School of Informatics and Engineering, The University of Electro-Communications, Tokyo, Japan, are designing and testing smart UAV systems via a recent-proposed theory for nonlinear control systems design and analysis. They have been carrying out a large number of flight mission experiments using the smart UAVs in Taiki, Hokkaido, Japan, over the last decade.
