Problems solved by technology

The belt-shaped fin propulsion device can realize the undulating motion of fins similar to fish under the drive of the motor, but due to the linear arrangement of the motors, it can only imitate the undulating motion of the dorsal and anal fins of archopterans and bare-backed eels Mode, lack of mobility in swimming, single movement mode
[0005] The above-mentioned bionic robotic fish swimming and propelling in the form of fluctuating fins and the propulsion mechanism both use strip-shaped long fins with motors arranged in a straight line as the propulsion device, which has poor swimming flexibility and can only imitate a single fish swimming mode

Embodiment Construction

[0023] The specific technical solution of the bionic robot stingray of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as Figure 2~5 As shown, the bionic robot stingray of the present invention consists of an upper casing 1, a lower casing 2, a propulsion mechanism 3, an energy source and a control system 4, an attitude adjustment mechanism 5 and a sinking control mechanism 6.

[0025] The upper shell 1 and the lower shell 2 are connected by screws 7, and in order to ensure that the bionic machine stingray does not leak when it swims underwater, a sealant is applied between the upper shell 1 and the lower shell 2. The propulsion mechanism 3 is composed of N servo motors 301 , N flexible fins 302 , one elastic fin surface 303 and N sealing rings 304 . The flexible fin 302 is an elastic plastic material that can realize flexible bending, and can produce flexible deformation under the action of surrounding fluid resista...

Abstract

The invention relates to a bionic robot stingray and a movement method thereof, which belong to the technical field of bionic robot stingrays. The bionic robot stingray comprises an upper shell, a lower shell, a propelling mechanism, a floating control mechanism, a gesture adjusting mechanism and an energy source and control system. High-speed swimming movement of the bionic robot stingray can be realized by the aid of a fish tail fin swing simulation propelling mode, and high-maneuverability swimming movement of the bionic robot stingray also can be realized by means of simulating fish pectoral fluctuating movement and jellyfish floating movement. The bionic robot stingray can be used in a swimming movement mechanism for researching fishes, and also can be used for relevant fields such as underwater detection, reconnaissance and the like.

Description

technical field [0001] The invention relates to a bionic underwater robot fish and its movement mode, belonging to the technical field of bionic robot fish. Background technique [0002] The ocean area accounts for 71% of the earth's area, and there are rich biological resources and mineral resources in the ocean. The 21st century is called the century of the ocean. The pace of human development and utilization of the ocean is gradually accelerating with the development of science and technology. The underwater robot (Unmanned Underwater Vehicle, UUV) with the functions of marine survey, seabed exploration, marine salvage, detection of artificial underwater structures such as pipelines, and underwater detection and tracking has become an important tool for exploring, developing marine resources and marine defense. important tool. [0003] It has become the goal pursued by researchers to imitate the swimming propulsion mode of fish and develop high-efficiency, low-noise, fl...
