Recently, soft actuators gather attention. They have the characteristics of a natural and flexible movement as human's movement. However, the actuators which have already been developed are inferior the performance, such as efficiency, flexibility and self-repairability, compared to human's muscle. In this study, we proposed a novel soft actuator using magnetic fluid that imitated the structure of human's muscle. We call it artificial muscle type actuator. At first step of this study, the linear movement type actuator combined permanent magnets and magnetic fluid is developed, and various characteristics of magnetic fluid are measured. As a result, we discovered the increase of the magnetic flux density between magnetic poles and the produced power using magnetic fluid.
