SYSTEM FOR REGULATING STIFFNESS BASED ON CHANGES IN EXTERNAL FORCE

摘要

According to an embodiment of the present invention, disclosed is a system for regulating stiffness based on changes in external force which comprises: a rotary shaft which rotates a passive member by being combined with the same; a rotary connector which is connected to the rotary shaft for rectilinear motion in a longitudinal direction of the rotary shaft, and is rotationally driven by being delivered with driving force from a driving motor; an elastic connector comprising plate springs which are extended in the longitudinal direction of the rotary shaft and connected to the rotary connector in order for a support fixed to the rotary shaft and the rotary connector to perform rectilinear motion; an external force measuring unit which measures external force added to the passive member based on transformations of the plate springs; and a stiffness regulating unit which regulates stiffness by controlling connection locations of the rotary connector and plate springs based on measured external force.
