Problems solved by technology

However, the starting point of this structural design is more like a boat moving forward by paddling, and it does not coincide with the swimming mechanism of fish. In addition, this structural design will increase the lateral size of the robotic fish, to a certain extent Reduced the mobility of the robotic fish

Abstract

The invention provides a bionic robot fish based on double tail fin drive. The bionic robot fish comprises a base body and a driving part arranged in the base body, wherein the driving part comprises an inner fixing frame as well as a tail fin driving unit and a gravity center adjusting mechanism which are arranged in the inner fixing frame, the tail fin driving unit comprises two tail fin driving devices with the same structure, and the two tail fin driving devices are symmetrically arranged on two sides of the inner fixing frame; the base body comprises a cavity and a tail fin group, the cavity is formed by buckling a first casing and a second casing, and the tail fin group comprises a first tail fin and a second tail fin which are longitudinally and symmetrically arranged in the second casing and connected to the tail fin driving devices corresponding to the first tail fin and the second tail fin. The bionic robot fish can solve the problem of yawing of a tail fin pushing type robot fish and can keep good maneuverability.

Description

technical field [0001] The invention relates to an underwater submersible, in particular to a bionic robot fish driven by double tail fins. Background technique [0002] The ocean area of ​​the earth is 361 million square kilometers, accounting for about 71% of the total area of ​​the earth. The vast ocean contains rich mineral resources, and the reserves of species resources in the ocean are huge. As resources become the focus of attention on a global scale As well as the development of marine survey technology, the development and utilization of marine resources has become the focus of attention of countries all over the world. Starting from the drive and structure, the underwater robot realizes the bionicity of the shape and motion of underwater creatures (fish), and uses smart devices to replace humans to realize underwater detection. It has broad application prospects and huge potential in military reconnaissance and other fields. potential value. [0003] According t...
