Abstract
Recently, a small-sized humanoid robot is often used by education. However, as for their most, a sensor is not put on. It is difficult to be installed in order that a sensor records data to a small-sized robot. Then, we already developed the ZMP sensing device which a robot could install. Furthermore, we developed the motion analysis system of the robot by the image. By using this system, we got possible to do the measurement of the motion of the hands and feet which ZMP sensing device cannot measure. Therefore the student can perform an experiment more effectively.
