A desire to further comprehend the hydrodynamic characteristics of three-dimensional undulating fin propulsion is what motivates work. First, a high-resolution numerical technique based on constraint immersed boundary method utilized simulate fluid-fin system. The simulation results reveal fundamental variation laws between performance and kinematic parameters. According data, an in-depth analysis scaling law conducted. key contribution this work build force formula extend complicated cases...
The unique rigid-flex connection between the fin-rays and fin-surface in a bionic undulatory fin robot endows with both active flexibility load-bearing capacity, enabling this to perform amphibious motions underwater, terrestrial, even marshy environments. However, investigations into dynamic modeling problems for robot, considering impact of nonlinear deformation frictional contact on ground locomotion performance, are scarce. Given this, based absolute nodal coordinate formulation (ANCF),...
The black ghost knifefish is considered to possess central pattern generators (CPGs), which generate rhythms in neural circuits coordinate the deformation of its elongated ribbon fin for efficient and agile locomotion. Currently, biomimetic robots, imitating motion operating under undulating propulsion control method, present significant challenges adapting their swimming gaits variable environments tasks. To overcome this limitation, paper conducts bio-robotic research that extends from...
