Abstract

The invention discloses a deep diving bionic stay wire robotic fish, belongs to the technical field of bionic robotic fishes, and mainly solves the problems that an existing robotic fish can only swimin a shallow water area and cannot realize deep water operation. The robotic fish comprises a fish head part, a middle joint and a flexible tail part which are connected in sequence. The fish head part is provided with a camera device, a gravity center adjusting device, a buoyancy adjusting device, a motor driving device and a transmission device used for connecting the gravity center adjusting device and the motor driving device. The middle joint is formed by sequentially connecting a plurality of joint bodies in a hinged mode, two pull wires sequentially penetrating through wire grooves inthe upper ends and the lower ends of the joint bodies are arranged between the motor driving device and the flexible tail, and the motor driving device and the flexible tail are in transmission through the pull wires. The device is simple in structure and easy to control and has high practical value.

Description

technical field [0001] The invention relates to the technical field of bionic robotic fish, and more particularly, to a deep-dive bionic robotic fish. Background technique [0002] As the most common creature living in water, fish, after a long period of evolution, has fully adapted to survive in water, and its flexible and fast swimming in water has aroused the strong interest of scientific researchers. Researchers have studied the swimming mode of fish in an attempt to unravel the mystery of their swimming. The study found that the swimming mode of fish has higher efficiency and less noise than the traditional propeller-driven way. Etc. In recent years, a variety of bionic robotic fish have been designed and manufactured, some imitating sharks, and some imitating rays, all of which imitate the way fish swim well. [0003] However, most of the current robotic fish imitating the swimming mode of fish are driven by multiple joints and multiple motors, and the structure and ...
