Research Areas

Our main interest is to analyze the motion and the mechanics of moving systems, to develop the way the systems are designed and controlled, and to realize the physical concepts in the real world. This includes both mechanical (e.g., robots, construction machineries, mechanism components, etc.) and biological systems (e.g., humans, animals, insects, etc.). The current research trend shows that the mechanical modeling of robotics can be extended to more complicated biological systems. We also believe that the analysis of motion principles and structures in the nature will provide innovative ideas for design and control of novel mechanisms.
