Abstract
Today, electric motor actuates most of the robots. It restricts the shape of them because of its package and its movements and more or less makes some noise. In this study, I designed a robot actuated by a metal fiber, I call it “Linear-Actuator”, and It has folding structure. It can be free of the restriction for shaping, weight light, and move silently. It can move independently by a micro computer and a infrared sensor fixed on its surface.
