In this paper, we propose a new robotic catapult with a high stiffness endpoint. The conventional robotic catapults based on the closed elastica are the robotic elements for generating impulsive motions by utilizing the snap-through buckling. In a typical closed elastic catapult, the two ends of an elastic strip are fixed to a free joint and an active joint, respectively. Here we found that by adding only the high stiffness at the free joint, compared to the conventional type, more impulsive motion repeatedly. By utilizing the proposed robotic catapult based on the closed elastica with a high stiffness endpoint, we develop a novel swimming robot which can swim not only continuously but briskly from a stationary state.
