Compared with traditional underwater vehicles, bio-inspired fish robots have the advantages
of high efficiency, high maneuverability, low noise, and minor fluid disturbance. Therefore …

The traditional propeller-based propulsion of underwater robots is inefficient and poorly
adapted to practice. By contrast, underwater biomimetic robots show better stability and …

Recent research on robotic fish mainly focused on the bionic structure design and realizing
the movement with smart materials. Although many robotic fish have been proposed, most of …

Aquatic robotics is making a critical transition to adapt and inspire more efficient systems
from nature. The result is the abandonment of inefficient propeller-based locomotion for a …

In this paper, the current state of research on underwater vehicle stability is analyzed based
on different criteria. The relevant literature in the China National Knowledge Infrastructure …

A major difference between manmade underwater robotic vehicles (URVs) and undersea
animals is the dense arrays of sensors on the body of the latter which enable them to …

Underwater robots are useful for exploring valuable resources and marine life. Traditional
underwater robots use screw propellers, which may be harmful to marine life. In contrast …
