In nature, fish can achieve efficient swimming through vortex control, which is also a crucial factor in the propulsion of biomimetic robotic fish. Existing analytical models generally do not consider vortices. addition, numerical methods for solving fluid dynamics are complex and computationally intensive. this article, based on discrete method (DVM), point circulation caused by tail oscillation calculated an accurate dynamic model established. Specifically, single-joint fish, hydrodynamic...

Benefiting from the potential advantages of low noise, high efficiency and little disturbance, bionic propulsion has attracted wide attentions. Compared with rigid structure, performance elastic structure such as flexible caudal fin passive compliant joint been improved, yet effective frequency range is limited due to single mechanism. The optimal can only be produced in a certain range. In this article, biological peduncle integrated composite mechanism elasticity shear damping proposed,...

Fish have attracted a huge number of researchers in recent years due to their exceptional swimming abilities, and many imitation fish propulsion robots been produced. Numerous studies demonstrated that obtain the best speed efficiency by adjusting stiffness bodies when tail beats at different frequencies, yet most contemporary robotic neglect body. In this article, we create fishtail with elastic materials, which is combined hard silicone cylinder several regularly arranged balls cylinder....

Abstract The robotic fish utilizes a bio-inspired undulatory propulsion system to achieve high swimming performance. However, significant roll motion has been observed at the head when tail oscillates certain frequencies, adversely affecting both perception accuracy and efficiency. In this paper, torque acting on is theoretically analyzed decomposed into gravitational, inertial, hydrodynamic components. Resonance identified as key factor amplifying response. To mitigate enhance stability,...
