STIFFNESS GENERATION APPARATUS USING MAGNETORHEOLOGICAL FLUID, APPARATUS PROVIDING PASSIVE HAPTIC FEEDBACK USING THE SAME, MICROMINI MOVING DEVICE USING THE SAME AND CONTROL METHOD

摘要

PURPOSE: A stiffness generating apparatus using magnetorheological fluid, an apparatus providing haptic feedback using the same, a micromini moving device using the same, and a control method thereof are provided to supply an elastic force through an elasticity providing unit and receive magnetorheological fluid, thereby miniaturizing the stiffness generating apparatus. CONSTITUTION: A housing(10) receives MRF(Magnetorheological Fluid). A press plate(20) is placed on the housing. An external force is applied to the press plate. A piston(30) is connected to the press plate and reciprocates in the housing in one direction. An elasticity providing unit(40) is placed between the press plate and the piston, provides elasticity to a press plate moving by the external force, and receives MRF and simultaneously provides elasticity. A magnetic field applying unit(60) is installed in the housing to apply a magnetic field to the MRF.
