Rechargeable robotic fish

Abstract

The invention relates to a rechargeable robotic fish which shares a drive and power generation device. The drive or power generation device is used for making a dorsal fin or a fish body generate the traveling wave motion. The front end of the dorsal fin or the fish body is connected with the drive device. In the propelling process, the drive device is driven by a motor, the dorsal fin or the fish body conducts the traveling wave motion and acts on water or air, and thrust is obtained. In the power generation process, flowing water or wind acts on the dorsal fin or the fish body, transmission mechanisms on corresponding joints of the dorsal fin or the fish body are driven, the dorsal fin or the fish body conducts the traveling wave motion, and therefore the drive or power generation device conducts power generation and charging. The rechargeable robotic fish can be automatically charged in a flowing water area, and therefore the robotic fish can be truly used for the aspects such as complex and dangerous underwater environment operation, military reconnaissance, underwater salvage, marine organism observation and archaeology. In the windy environment, the rechargeable robotic fish out of water can be charged similarly.

Description

technical field [0001] The invention relates to a robotic fish, in particular to a robotic fish that can be charged by traveling wave water flow or wind power. Background technique [0002] Fish is the earliest vertebrate in nature. After millions of years of natural evolution, it has sustained speed, high efficiency and large thrust-to-weight ratio. The streamlined body shape of fish has good hydrodynamic properties, and their superb swimming skills are far superior to the existing navigation skills of human beings. [0003] There are several ways for fish to propel, and traveling wave propulsion is one of the important ones. This type of fish is characterized by a relatively flat body such as eel and hairtail, or an oval or striped body such as salmon and salmon, or has a large dorsal fin. The traveling wave movement of the body or dorsal fin is used to generate thrust. This kind of propulsion method has high efficiency and good maneuverability. [0004] For nearly half...

Problems solved by technology

[0006] However, like other mobile robots, the biomimetic robot fish also faces an important constraint—the energy problem. From the perspective of energy storage, several sets of batteries can be prepared for backup, but due to the additional increase in weight and volume, the payload Capacity and efficiency will be reduced accordingly

Existing bionic robotic fish cannot travel far and can only work within a small working radius
