National Institute of Technology, Wakayama College (Wakayama KOSEN), Japan
Department of Intelligent Mechanical Engineering, Associate Professor
I'm interested in distributed controls and estimations for multi-robot systems and swarm robots. Especially, I study about network topology control methods for cooperative behaviors of robots. Furthermore, I educate KOSEN students about control, measurement and information engineering using a multi-robot system.
