Research on fish locomotion has expanded greatly in recent years as new approaches have
been brought to bear on a classical field of study. Detailed analyses of patterns of body and …

As a result of years of research on the comparative biomechanics and physiology of moving
through water, biologists and engineers have made considerable progress in understanding …

Soft robotics aims at creating systems with improved performance of movement and
adaptability in unknown, challenging, environments and with higher level of safety during …

Numerical simulations are used to investigate the hydrodynamic benefits of body–fin and fin–
fin interactions in a fish model in carangiform swimming. The geometry and kinematics of the …

Recent studies have shown that by utilizing the interactions among median fins (the dorsal,
anal, and caudal fins), fishes can achieve higher propulsion performance at the caudal fin …

Animal movements result from a complex balance of many different forces. Muscles produce
force to move the body; the body has inertial, elastic, and damping properties that may aid or …

We designed a robotic fish caudal fin with six individually moveable fin rays based on the tail
of the bluegill sunfish, Lepomis macrochirus. Previous fish robotic tail designs have loosely …

Numerical simulations have been used to analyze the effect that vortices, shed from one
flapping foil, have on the thrust of another flapping foil placed directly downstream. The …

Numerical studies are presented on the propulsive performance and vortex dynamics of
multiple hydrofoils pitching in an in-line configuration. The study is motivated by the quest to …

The fins of fishes are remarkable propulsive devices that appear at the origin of fishes about
500 million years ago and have been a key feature of fish evolutionary diversification. Most …
