Left: Our aerial vehicle transforms from a helicopter to an air plane. Right: Our robot has a different signal configuration from ASIMO, BigDog. In the futureAfter graduationA new modeling and control of hydraulic robots in our laboratory attracts one or two of the world biggest construction machinery companies/heavy industrial companies. From our laboratory, you will see actual and serious robotic problems (e.g., Fukushima problems). A new camera based modeling and control also attracts academic researchers since our method is free from the geometric feature extractions which strongly restrict applications. In our laboratory, you can enjoy new robotics in this century. Many students will be the master students for research and development in robotic systems and control. They will present their results in the highly-valued international conferences or journals. They can be control engineers as well as mechanical engineers (in Hitachi, Fujitu etc.).
