Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Effect of Fin Area and Contorol Methods on Reduction of Rool Motion with Fin Stabilizers

JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1993
This paper discusses some investigations on the influence of the fin area of a fin stabilizer and the control method on the reduction of roll with the fin stabilizer in view of full scale test results. In order to select the optimum fin area, it is important to use not only empirical wave slope capacity, but simulation including rolling probability ...
