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 …

The morphology, physiology, and behavior of marine organisms have been a valuable
source of inspiration for solving conceptual and design problems. Here, we introduce this …

We present experimental results on the role of flexibility and aspect ratio in bio-inspired
aquatic propulsion. Direct thrust and power measurements are used to determine the …

Robotic systems are becoming more ubiquitous, whether on land, in the air, or in water. In
the aquatic realm, aquatic drones including ROVs (remotely operated vehicles) and AUVs …

The design of soft robots capable of navigation underwater has received tremendous
research interest due to the robots' versatile applications in marine explorations. Inspired by …

Experimental and analytical results are presented on two identical bio-inspired hydrofoils
oscillating in a side-by-side configuration. The time-averaged thrust production and power …

This article serves as an overview of the unique challenges and opportunities made
possible by a soft, jellyfish inspired, underwater robot. We include a description of internal …

Rajiform locomotion in fishes is dominated by distinctive undulations of expanded pectoral
fins. Unlike other fishes, which typically interact with the fluid environment via multiple fins …

Inviscid computational results are presented on a self-propelled virtual body combined with
an airfoil undergoing pitch oscillations about its leading edge. The scaling trends of the time …

Oscillating pectoral fins' spanwise flexibility is a key factor influencing the forwarding
propulsion performance of bionic cownose rays, including thrust and heave-pitch stability …
