The artificial muscle has flexibility and lightness which arranged fiber by air pressure. The artificial muscle has allow a robot to contact with human and object safely. Furthermore, flexibility and lightness which allow a robot to contact with its high output density can be used for practical task. We are aiming human and object safely. Furthermore, its high output to put it into practical application by improving structure and density can be used for practical task. We are aiming to put material sides.it into practical application by improving structure and We are also developing soft robots which are driven by artificial material sides.muscles. A self-deformation robot with frame structure composed of We are also developing soft robots which are driven by artificial muscles. A self-deformation robot with frame artificial muscles can rolling by deformation own shape because it structure composed of artificial muscles can rolling by does not have rigid mechanism. Furthermore, this lightweight deformation own shape because it does not have rigid actuator has advantage in developing a multi-degree of freedom mechanism. Furthermore, this lightweight actuator has manipulator, thus, we are developing and controlling of the flexible advantage in developing a multi-degree of freedom manipulator like an elephant nose.manipulator, thus, we are developing and controlling of the flexible manipulator like an elephant nose.Appealing point：We pursue the research in order artificial muscles to be familiarized Special objectivesto the public.
