MULTI-DEGREE OF FREEDOM FORCE FEEDBACK DEVICE USING ER FLUID OR MR FLUID TO ACHIEVE CONTINUOUS, SMOOTH CONTROL IN A LOW TORQUE REGION

摘要

PURPOSE: A multi-degree of freedom force feedback device using ER(Electro-Rheological) fluid or MR(Magneto-Rheological) fluid is provided to regulate the control torque continuously and to gain desired torque immediately without forward/reverse switching of the drive motor.;CONSTITUTION: A multi-degree of freedom force feedback device(100,200) using ER fluid or MR fluid comprises a body, an outer sphere which is fixed inside of the body, an inner sphere which is joined within the outer sphere to move freely, and ER or MR fluid which is filled in the gap between the outer and inner sphere.;COPYRIGHT KIPO 2010
