Underwater robot designs inspired by the behavior, physiology, and anatomy of fishes can
provide enhanced maneuverability, stealth, and energy efficiency. Over the last two …

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 …

Undulatory swimming represents an ideal behavior to investigate locomotion control and the
role of the underlying central and peripheral components in the spinal cord. Many vertebrate …

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 …

Underwater wireless sensor networks are a newly emerging wireless technology in which
small size sensors with limited energy and limited memory and bandwidth are deployed in …

Body motions (kinematics) of animals can be dimensionally complex, especially when
flexible parts of the body interact with a surrounding fluid. In these systems, tracking motion …

This study applies renewable energy-based induction to key components of sophisticated
ornithopter unmanned amphibious vehicles (OUAVs). The flying fish-inspired natural drone …

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 …

A full understanding of the mechanics of locomotion can be achieved by incorporating
descriptions of (1) three-dimensional kinematics of propulsor movement,(2) material …

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 …
