Abstract: The present invention relates to a rotary actuator, and, more specifically, to a rotary actuator comprising: a solenoid forming a flux line by generating a magnetic field when applied with electric current; a cylindrical rotating part surrounding the inner surface, outer surface, and upper surface of the solenoid, including a rotary shaft positioned at a through-hole which is the central part of the solenoid, and freely rotating on the rotary shaft; a cylindrical housing surrounding the inner surface, outer surface, and upper surface of the solenoid, and the inner surface, outer surface, and lower surface of the rotating part, and coupled to mesh with the rotating part; and magnetic rheological fluid injected into the housing, positioned in assembling gaps among the solenoid, the rotating part, and the housing, and forming a magnetic chain along the flux line when the magnetic field is generated. According to the rotary actuator using the magnetic rheological fluid and a method for providing force feedback which are suggested by the present invention, the force feedback is provided by coupling the solenoid, the rotating part, the housing, and the magnetic rheological fluid with a new structure so that high resistance is obtained by low power, the actuator is miniaturized and lightened so as to be assembled and detachably attached to other devices, and to be applied to various environments.
