Laboratory for Space Systems (LSS); Engineering Sicences and Design/Mechanical Engineering, Mechanical Engineering, School of Engineering, Tokyo Institute of Technology, is dedicated to studying and developing novel space robotic systems since 1992 based on large-scale flexible multibody dynamics and control. We are conducting research works on reconfigurable space systems such as Reconfigurable Brachiating Robot (RBR) systems to be tested on Japanese Experimental Module (JEM) of the International Space Station (ISS), robot satellite cluster systems, astronaut-assisted smart devices and so on. In addition, we are actively engaged in international university cooperated development of small satellite systems since 1998: CanSat, CubeSat, Mother-ship Daughter-ship small docking mechanisms, international ground operation network system, and so on.
