Bionic robotic fish with multi-drive system

Abstract

A bionic robotic fish with a multi-drive system comprises a shell, fins and a fishtail; the fins are rotationally and symmetrically arranged on the left side and the right side of the shell; the fishtail is movably connected to the outer portion of the right end of the shell through a swing assembly; a pair of high-definition cameras are symmetrically installed on the left side of the shell; a signal receiver is further arranged in the shell' the interior of the shell is of a cavity structure, and a floating and diving assembly is arranged at the left end of the shell and used for controllingfloating and diving of the robotic fish; the end, extending into the shell, of each fin is rotationally connected with an action executing assembly through a wedge-shaped plate so as to achieve intermittent swing of the fin; a battery box is fixed to the middle of the shell and used for providing electric energy for internal electronic components of the shell. the swing assembly is used for controlling the fishtail to swing so as to achieve bionic swimming of the robotic fish in water.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, in particular to a bionic robot fish with a multi-drive system. Background technique [0002] The bionic robot fish is designed and manufactured according to the principles of bionics, and is mainly used in the detection of pollutants in water, biological observation, and detection in small spaces. Because the bionic robot fish has a high camouflage shape and high mobility, therefore, Bionic robot fish will play an important role in complex and dangerous underwater environment operations, military reconnaissance, marine life observation, archaeology, etc. However, according to the survey, the existing bionic robot fish often have the following problems: [0003] 1. The drive system is single, resulting in reduced flexibility, unable to meet the needs of underwater work under various complex working conditions; [0004] 2. The tail swing mechanism adopts rigid connection. On the one hand, t...

AI Technical Summary

Problems solved by technology

[0003] 1. The drive system is single, resulting in reduced flexibility, unable to meet the needs of underwater work under various complex working conditions;

[0004] 2. The tail swing mechanism adopts rigid connection. On the one hand, the overall speed of the robot fish is slowed down, which affects the underwater work efficiency. The water flow cannot be effectively buffered when the fish tail swings, which makes the robot fish prone to yaw or even roll over during its travel;

[0005] 3. Adjust the direction of travel of the robot fish by changing the unilateral swing range of the tail. The turning radius is large, and it is almost in a static state when turning, which greatly reduces the flexibility of the robot fish.
