Embodiment Construction

[0044] In order to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] Such as figure 1 As shown, a bionic robot fish includes a head 1, a trunk and a tail 3 connected in sequence.

[0046] The front end of the head 1 has an elongated tip structure 11, and the outer surface of the head 1 is a streamlined structure. A dorsal fin 12 is installed on the top of the rear half of the head, and pectoral fins 13 are installed symmetrically on both sides of the rear half of the head. The dorsal fin installation groove and the pectoral fin installation groove are arranged on the head of the bionic robot fish, and the dorsal fin 12 and the pectoral fin 14 are respectively installed in the corresponding installation grooves. Keep upright during the moving process to avoid rollover and improve the reliability of its work.

Abstract

The invention discloses a bionic robot fish and relates to the technical field of underwater robots. The bionic robot fish structurally comprises a head portion, a body portion and a tail portion which are sequentially connected; the front end of the head portion is provided with a thin and long sharp-end structure; the outer surface of the head portion is of a streamline structure; the body portion comprises a fish skin and a propelling system; the overall shape of the fish skin is of a streamline structure; a plurality of grooves are distributed in the upper edge of the fish skin side by side in the direction of the long axis of the fish skin; the propelling system drives the body portion to swing to achieve underwater movement of the bionic robot fish; and the tail portion comprises a tail fin support and a tail fin. The bionic robot fish reduces fluid resistance during swimming, is reliable in work and is high in bionic degree.

Description

technical field [0001] The invention relates to the technical field of underwater robots, in particular to a bionic robot fish. Background technique [0002] With the continuous development and utilization of marine resources by humans, today's Autonomous Underwater Vehicle (AUV) has become an important platform for human ocean research and exploration. In recent years, with the continuous exploration of the understanding of fish swimming mechanism and the development of related manufacturing technology and control technology, an underwater submersible using the bionic propulsion mechanism of fish body has emerged as the times require. It provides a new way of thinking for underwater vehicles with high performance, low noise and easy concealment. [0003] The robot fish is an underwater submersible that uses the swimming mechanism of fish to achieve propulsion. It is equipped with various micro sensors and uses advanced control and communication methods to form a set of sen...
