A collaborative and interdisciplinary strategy spanning hydrodynamics, sophisticated
materials, elasticity, and microelectromechanical systems technologies is required for the …

Penguins are adapted to underwater life and have excellent swimming abilities. Although
previous motion analyses revealed their basic swimming characteristics, the details of the …

Otariidae are excellent swimmers and the only ones among the marine mammals that use
foreflippers for propulsion. Taking California sea lion as the bionic prototype, this article …

Biological fish can always sense the state of water flow and regulate the angle of attack in
time, so as to maintain the highest movement efficiency during periodic flapping. The …

Diving birds are regarded as a classic example of morphological convergence. Divers tend
to have small wings extending from rotund bodies, requiring many volant species to fly with …

Penguins perform lift-based swimming by flapping their wings. Previous kinematic and
hydrodynamic studies have revealed the basics of wing motion and force generation in …

Typically, a twisting morphing wing of flying or swimming robots has one spanwise shaft and
many ribs, the ribs can swing in their individual planes perpendicular to the shaft or the …

The penguin is the fastest underwater swimmer among the wing-propelled diving birds. To
figure out the mechanism for its excellent swimming, the hydrodynamic performance of a …

Penguins have evolved excellent swimming skills as diving birds, benefiting from their agile
wings. This paper experimentally analyzes the effects of the wing sweepback angle on thrust …

The rhythmic movement of bioinspired robotic fish brings about undesirable visual jitter.
Note that the unstable camera path of this kind of robot is characterized by obvious regularity …
