Fish commonly execute rapid linear accelerations initiated during steady swimming,yet the function of the median fins during this process is less understood.We find that the erection/folding time(from the starting tim...
Tuna,known for high endurance cruising,have already inspired several underwater robots and swimming studies.This study uses a biomimetic robotic tuna to investigate how different caudal fin planform geometries affect ...

In this paper, study of a novel flexible robotic-fin actuated by Shape Memory Alloy (SMA) is presented. The developed robotic fin is capable of implementing various 3-Dimensional (3D) motions, which plays an impor...
The performance ofbluespotted rays was emulated in the design ofa bioinspired underwater propulsor in the present work. First, the movement of a live bluespotted ray was captured for the swimming mode and useful infor...
Biological evidence suggests that fish use mostly anterior muscles for steady swimming while the caudal part of the body is passive and, acting as a carrier of energy, transfers the momentum to the surrounding water. ...

A robotic fish driven by oscillating fins, 'Cownose Ray-I', is developed, which is in dorsoventrally flattened shape without a tail. The robotic fish is composed of a body and two lateral fins. A three-factor kinemati...
Fishes are famous for their ability to position themselves accurately even in turbulent flows. This ability is the result of the coordinated movement of fins which extend from the body. We have embarked on a research ...
