As a man-machine interaction increases its importance in robotics and mechatronics fields, a soft robot inspired from natural systems becomes one of the research trends. There are several research topics related to soft robots such as soft structures or artificial skins, compliance control, soft actuators or artificial muscles, and so on. For the natural muscle potentially has great flexibility, the authors believe the artificial muscle actuator must have a great potential in soft robots. Hence in this study we develop a new type of micro artificial muscle cell, which is an element of an integrated artificial muscle, using electro-conjugate fluid and measure its driving performances. In addition, position control characteristics are also clarified by experiments. As a result, the micro artificial muscle cell using electro-conjugate fluid shows quite good control performances.
