In this study, the passive jumping mechanism based on the jumping principle of click beetles is proposed. The proposed mechanism consists of two links, a peg made from viscoelastic material, and springs. When an external force is applied to extend the joint, the joint is temporarily fixed in an extend state. Then, If the mechanism is placed on the ground and wait for a few seconds in this state, the joints will be released and the mechanism will jump. In this paper, we fabricated a prototype of a passive jumping mechanism and it was confirmed that the proposed mechanism is possible to jump in passively.
