Although methods about building fish-like robots have attracted much research in recent years, new techniques are still required for developing superior robot fish. This paper presents a novel robot fish propelled by an active compliant propulsion mechanism. The key innovation is the combination of an active wire-driven mechanism with a soft compliant tail to accomplish subcarangiform swimming ...

In the world of underwater robotics, fish-like structures are able to accelerate and maneuver better than most other artificial underwater vehicles. For these reasons, fish-like robots are well suited for submarine exploration tasks. However, a complete understanding of mechanisms governing the swimming movements of fish-like robots remains elusive, limiting the performance of such underwater r...

Underwater robots are widely used in the fields of ocean development, ocean investigation and marine environmental protection. They need higher efficient of propulsive performance. In order to get an underwater robot with high propulsion efficiency, we have studied on a fishlike swimming mechanism and developed a prototype fish robot. It has about 600 mm body length, and three joints of a tail ...

The possibility of integrating bioinspired robots in groups of live social animals may constitute a valuable tool to study the basis of social behavior and uncover the fundamental determinants of animal functions and dysfunctions. In this study, we investigate the interactions between individual golden shiners (Notemigonus crysoleucas) and robotic fish swimming together in a water tunnel at con...

Simulation system is charged with the strategy validation and dual team meets, and as the 2dimensional simulation platform for underwater robotic fish game, URWPGSim2D is the assigned platform for Chinese underwater robot contest and Robot cup underwater program. By now on URWPGSim2D, there is only static obstacles, thus short of changeableness. In order to improve the changeableness and innova...

This paper focuses on the modelling and control problems of a self‐propelled, multimodal amphibious robot. Inspired by the undulatory body motions of fish and dolphins, the amphibious robot propels itself underwater by oscillations of several modular fish‐like propelling units coupled with a pair of pectoral fins capable of non‐continuous 360 degree rotation....
