Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] The flexible pectoral fin swing type underwater bionic robot of the present invention is based on the principle of bionics, by using the characteristics of low frequency, low resistance, high efficiency, and high maneuverability of the underwater pectoral fin swing propulsion mode, a distribution driven by pneumatic artificial muscles is designed. A type of flexible internal skeleton and a flexible body of the pectoral fin swing-propelled bionic robot. Generally, the bionic robot includes two parts: an air source and a bionic structure.

[0048] See figure 1 , Figure 1A As shown, the flexible pectoral fin swing type underwater bionic robot of the present invention is composed of a left swing assembly 1, a right swing assembly 2, a tail swing assembly 3, a support assembly 4, a left flexible wing 5, and a right flexible wing 6. ; The left flexible wing 5 an...

Abstract

The invention discloses a flexible pectoral fin swing type underwater bionic robot, consisting of a left swinging component, a right swinging component, a tail swinging component, a supporting component, a left flexible wing and a right flexible wing; the left flexible wing has the same structure with that of the right flexible wing, the two wings are symmetrically assembled by taking the longitudinal axis as a center to form a flexible body, the left swinging component, the right swinging component, the tail swinging component and the supporting component are arranged inside the flexible body, and an air supply is arranged outside the flexible body; the supporting component is arranged along the longitudinal axis, the left swinging component and the right swinging component are respectively arranged at the left side and the right side of the supporting component, and the tail swinging component is arranged at the rear end of the supporting component; and the left swinging component has the same structure as that of the right swinging component. The bionic robot adopts the external air supply to drive pneumatic artificial muscles, so as to realize moving forwards, turning and heave movement of the bionic robot in water.

Description

Technical field [0001] The invention relates to an underwater bionic robot, more particularly, it refers to a flexible pectoral fin swing type underwater bionic which imitates the swinging and swimming of both pectoral fins in the ocean and uses pneumatic artificial muscles robot. Background technique [0002] The flexible pectoral fin swing propulsion biomimetic robot (fish) can achieve low-frequency, low-resistance, high-efficiency, and high-maneuverability underwater movement. It has a wide range of applications in the fields of underwater detection and military reconnaissance. At present, the existing bionic robots (fish) at home and abroad can be roughly divided into two types according to the different body parts used for propulsion: ①Body and caudal fin propulsion mode-using the bending wave of the body similar to snakes or eels or the periodicity of the caudal fin The reciprocating swing produces propulsion; ②The middle fin, the fin propulsion mode-the use of the middle ...
