Inspired by the characteristics of high maneuverability and agility of live dolphins, a novel robotic dolphin based on both morphology and locomotion bio-mimicry is developed. The robotic dolphin consists of four main components involving a streamlined head, a turning unit, a dorsoventral undulatory structure, and a tail fluke. The streamlined body in conjunction with a vivid dorsal fin, pectoral...
This paper addresses the design scheme of a multi-mode amphibious biomimetic robot inspired by amphibians, as well as preliminary development of the robotic prototype. The robot is capable of both fish-like swimming and dolphin-like one under water, in which a swivelling body device is responsible for switching between them. Meanwhile, for ground-based movements, the introduction of the flippers or...
We develop a practical motion control strategy for a radio-controlled, 4-link and free-swimming biomimetic robot fish that uses a flexible posterior body and an oscillating foil as propulsor. Because motion control of robot fish involves hydrodynamics of the fluid environment and dynamics of the robot, it is very difficult to establish a mathematic model employing purely analytical methods. The fish's...
