Problems solved by technology

Underwater submersibles in the traditional sense are huge in size, complex in overall mechanism and high in noise. Although after years of unremitting improvement, there have been many stable and satisfactory products, they only work in the wide underwater field. , underwater voids and other areas are seldom paid attention to

Embodiment Construction

[0029] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0030] combine figure 1 combine figure 2 , the composition of the underwater miniature bionic robot fish includes a hemispherical head 9, a body and a pair of push tails, two miniature infrared photoelectric sensors 1 are installed on the front end of the hemispherical head, and the body is connected to the hemispherical head and the push tail between; the telescopic body is made up of memory alloy spring 3 and light compression spring 4 outside the memory alloy spring; the pair of pushing tails is made by bonding two pieces of ICPF material 7 and fan-shaped plastic sheet 8, Installed side by side on both sides of the telescopic housing. The memory alloy spring and the ICPF are respectively connected to external circuits through wires. Simultaneously combined image 3 with Figure 4 , the trunk is connected with the hemispherical head, the trunk and the tail...

Abstract

The invention provides an underwater minitype biomimetic robot fish, comprising a hemispherical head, a body and a pushing tail. The front end of the hemispherical head is provided with two minitype infrared photoelectric sensors; the body is connected between the hemispherical head and the pushing tail, which is a telescopic body that consists of a memory alloy spring and a light compression spring that is sheathed outside the memory alloy spring; the pushing tail is provided with two ICPF fish tails which are arranged in parallel at the two sides of the telescopic shell. The memory alloy spring and the ICPF are respectively connected with an external circuit by light leads. The invention provides the underwater minitype biomimetic robot fish with power supplied by low voltage, driven by novel intelligent material and ultra-low noise. The underwater minitype biomimetic robot fish is designed by combining the characteristics of floating and submergence of jellyfish and tail swing advancing of fishes after researching multiple motion types of normal fishes.

Description

(1) Technical field [0001] What the present invention relates to is a kind of bionic, micro-robot, specifically miniature bionic robot fish. (2) Background technology [0002] At present, some miniature bionic robots have been or are being developed at home and abroad, such as some multi-legged insects, which can walk on irregular ground; miniature reconnaissance butterflies, which can be used for enemy surveillance. The biggest features of these bionic micro-robot insects are small size, light weight, low noise or even no noise. With the development of precision machining technology and the research and development of new intelligent materials, some research institutions at home and abroad have begun to explore the research field of underwater miniature submersibles. Underwater submersibles in the traditional sense are huge in size, complex in overall mechanism and high in noise. Although many stable and satisfactory products have emerged after years of unremitting improve...
