Dynamic modeling and experiment of hind leg swimming of beaver-like underwater robot [PDF]
Mechanical Sciences, 2022 When the beaver-like underwater robot is swimming, its hind legs provide the main propulsion force for the body, which is the source of power for the robot's movement.

Development of a Variable-Configuration Bionic Robotic Fish
Biomimetics, 2023 Bionic robotic fish have advantages over traditional underwater propulsion. Most of the existing studies have been conducted with only one type of fish as a bionic object, but a single propulsion mode may not be able to achieve the different needs of ...

A novel propulsion method of flexible underwater robots [PDF]
2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011 This paper presents aims at mobility improvement of flexible underwater robots. For this purpose, a novel propulsion method using planar structural vibration pattern is proposed, and tested on two kinds of prototypes. The result of experiments showed the possibility of the movements for multiple directions: forward, backward, turn, rotation, drift, and

Modeling and propulsion methods of underwater snake robots [PDF]
2017 IEEE Conference on Control Technology and Applications (CCTA), 2017 In this paper we consider underwater snake robots (USRs) that may be equipped with additional added effectors along their body, including caudal, dorsal and pectoral fins, tunnel thrusters and/or a stern propeller. We propose a mathematical model for USRs swimming in a 2D plane, which includes the extra propulsion forces acting on each link from the ...

Propeller optimization for underwater propulsion
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Annotation. This article is devoted to the optimization of an underwater propulsion propeller and the identification of the main dependencies in the first stages of optimization. A mathematical model and a parameterized 3d model with indication of variable parameters, as well as optimization criteria, are presented.
