Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] A kind of flexible pectoral fin swinging underwater bionic robot of the present invention is based on the principle of bionics, by utilizing the characteristics of low frequency, low resistance, high efficiency and high maneuverability of the underwater pectoral fin swinging propulsion mode, a distribution robot driven by pneumatic artificial muscles is designed. The pectoral fin swing-propelled bionic robot with a flexible internal skeleton and a flexible body. Generally, a bionic robot includes two parts: an air source and a bionic structure.

[0029] see figure 1 , Figure 1A As shown, a flexible pectoral fin swing underwater bionic robot of the present invention, the bionic structure 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 ;...

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 present invention relates to an underwater bionic robot, more particularly, it refers to a flexible pectoral fin swinging underwater bionic robot that imitates the body shape of a ray fish that swings and swims with bilateral pectoral fins in the ocean, and is driven by pneumatic artificial muscles. robot. Background technique [0002] The flexible pectoral-fin swing-propelled bionic robot (fish) can realize low-frequency, low-resistance, high-efficiency, and high-mobility underwater movements, and it has broad application prospects 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: ① body and tail fin propulsion mode - use the body bending fluctuation similar to snakes or eels or the periodicity of the tail fin The propulsion is generated by reciprocating swing; ②The prop...
