Compared with traditional underwater vehicles, bio-inspired fish robots have the advantages
of high efficiency, high maneuverability, low noise, and minor fluid disturbance. Therefore …

One of the emerging themes of fish-inspired robotics is flexibility. Adding flexibility to the
body, joints, or fins of fish-inspired robots can significantly improve thrust and/or efficiency …

Energy-efficient propulsion is a critical design target for robotic swimmers. Although previous
studies have pointed out the importance of nonuniform body bending stiffness distribution (k) …

With the development of materials science and micro–nano fabrication techniques,
miniature soft robots at millimeter or submillimeter size can be manufactured and actuated …

Fishes have learned how to achieve outstanding swimming performance through the
evolution of hundreds of millions of years, which can provide bio-inspiration for robotic fish …

Flexible slender structures are ubiquitous in biological systems and engineering
applications. Fluid-structure interaction (FSI) plays a key role in the dynamics of such …

Many fish propel themselves using wave-like lateral flexion of their body and tail in the
water. The undulatory body is driven by the distributed muscles, and locomotion is achieved …

In this paper, we numerically investigate the propulsive performance of three-dimensional
pitching flexible plates with varying flexibility and trailing edge shapes. We employ our …

Using fluid–structure interaction computational modelling, the hydrodynamic performance of
bio-inspired elastic propulsors with tapered thickness that oscillate in an incompressible …

We report results from an experimental investigation on the fluid-structure interactions of
flapping foils with tapered thickness profiles actuated in a quiescent viscous fluid. We seek …
