This research is a fundamental study on variable stiffness mechanism using electromagnet and spring. In this study, we develop an unit that can change the stiffness to the combination of the electromagnet with the spring. And, it's basic characteristic was examined. Next, the mechanism was modeled, and the control method of the stiffness. In addition, we examined whether it can control. As a result, it has been understood that stiffness is changed from 0.12kgf/mm to 0.165kgf/mm, and stiffness can be controlled but it takes time.
