Abstract : Generally, a highly rigid surgical robot enables accurate positioning, but may cause damage when it
contacts the surrounding tissue. We designed and fabricated a variable stiffness mechanism with a wide range
of low stiffness by setting one end of the elastic body as a free end. In this paper, the concept of mechanism,
implementation and its preliminary evaluation are introduced.
