Abstract: A passive compliance mechanism includes a fixing member, a base and a stiffness adjustment assembly. The base is installed on the fixing member, and includes two notches and an elastic slice. A first end of the elastic slice is connected with the base. A second end of the elastic slice is located near the outer periphery of the fixing member. The stiffness adjustment assembly includes a linear guide, a sliding block and two stopping blocks. The linear guide is installed on the fixing member. The sliding block is movably installed on the linear guide. The two stopping blocks are disposed on the sliding block and synchronously moved with the sliding block. The two stopping blocks are contacted with two opposite sides of the elastic slice to clamp the elastic slice. A stiffness of the base is adjustable according to a clamped position of the elastic slice.
