Numerical simulations are used to investigate the flow associated with a bluegill sunfish
(Lepomis macrochirus) pectoral fin during steady forward motion. The simulations are …

SUMMARY A biorobotic pectoral fin was developed and used to study how the flexural
rigidities of fin rays within a highly deformable fish fin affect the fin's propulsive forces. The …

For millions of years, aquatic species have utilized the principles of unsteady hydrodynamics
for propulsion and maneuvering. They have evolved high-endurance swimming that can …

The study of fish locomotion provides a rich source of inspiration for the design of robotic
devices. Fish exhibit an array of complex locomotor designs that involve both diversity of …

A bio-inspired prototype fish using the flexible matrix composite (FMC) muscle technology
for fin and body actuation is developed. FMC actuators are pressure driven muscle-like …

This letter presents a novel design of an oscillatory fin for thrust-efficient and agile
underwater robotic locomotion. We propose a flat paddle-fin comprising a set of overlapping …

Experimental analyses of propulsion in freely-swimming fishes have led to the development
of self-propelling pectoral and caudal fin robotic devices. These biorobotic models have …

A bio-robotic fin has been developed that models the pectoral fin of the bluegill sunfish as
the fish turned to avoid an obstacle. This work involved biological studies of the sunfish fin …

We investigate the thrust generation capacity of a thin foil consisting of a membrane
strengthened by embedded rays that is geometrically, structurally and kinematically similar …

A brute-force testing technique was applied on a robotic controlled-curvature flapping fin
propulsor to investigate output thrust and power consumption trends with respect to flapping …
