An Analyzing Method of Maneuverability

Journal of the Society of Naval Architects of Japan, 1975
The ship maneuverability has been described with the first order linear equation or the second order linear equation.However, we are under the necessity of the adoption of the second order equation with a nonlinear term as the mathematical model of the ship maneuverability, especially in case of full ships.This mathematical model is expressed byT1T2ψ+ (

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
