A New Type Large-Scale Water-Jumping Robot Design and Simulation

At present, the research on bionic water strider robots mainly focuses on the development of miniature skating and jumping prototypes. Duo to the small scale of robots, these robots shows poor load capacity, which limits their practical use. This paper proposes to design a large-scale water-jumping robot mimicking water striders. Compared with the miniaturized water strider robot, the new robot has a larger size and quality, which brings the difficulty in the jumping movement. In order to achieve a good jumping performance, the structure, size and other parameters of the robot should be carefully analyzed and optimized. This paper analyzed the design of the supporting leg, driving mechanism et al. Then a water-jumping robot prototype is proposed. In order to clarify the performance of the robot, a dynamic simulation model of the robot is established and analyzed based on the ADAMS dynamic analysis software. By changing the structural parameters of the robot, including the stiffness of the energy storage torsion spring, jumping angle and the center of gravity position et al., the jumping performance and the jumping posture of the robot are analyzed and the structural parameters of the robot are optimized. The results of the analysis help the fabrication of the robot and the follow-up experiments.
