Fishes suspended in water are subject to the complex nature of three-dimensional flows.
Often, these flows are the result of abiotic and biotic sources that alter otherwise uniform …

What mechanisms of flow control do animals use to enhance hydrodynamic performance?
Animals are capable of manipulating flow around the body and appendages both passively …

Inspired by the relatively simple morphological blueprint provided by batoid fish such as
stingrays and skates, we created a biohybrid system that enables an artificial animal—a …

Tunas are flexible, high-performance open ocean swimmers that operate at high
frequencies to achieve high swimming speeds. Most fish-like robotic systems operate at low …

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 …

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 …

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 …

Publisher Summary The chapter focuses on recent experimental hydrodynamic data on
undulatory locomotion in fishes, and provides a general description of the major theoretical …

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 …

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 …
