Embodiment Construction

[0016] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The overall structure of the robotic fish of the present invention is as follows: figure 1 As shown, a fish head, fish body, and fish tail three-stage structure is adopted, that is, the head driving section, the fish body that controls turning, and the tail.

[0018] The head has built-in battery box 2, receiver 1 and head servo 24. The receiver 1 and the battery box 2 are placed at the front end of the fish head, and the receiver 1 is placed on the top of the battery box 2, and both are fixed on the front baffle plate 26 of the head. The head servo 24 is fixed on the head tailgate 21 . The access line of the head servo 24 is connected to the channel of the receiver 1, and the remote controller controls the rotating shaft 23 at the output end of the head servo 24 to rotate left and right, and a disc 25 is fixed on the top of the rotat...

Abstract

A robotic fish adopts a three-stage structure of a head drive system, a middle section control system and a tail balance servo system. The head drive system includes a servo machine, a battery box and a receiver, and the head servo machine is connected to the receiver through a channel. , The middle part of the control system has a built-in servo connected to the second channel of the receiver. The joint between the head and the middle part adopts a waterproof sealing sleeve to realize dynamic sealing, and is linked by a double rocker mechanism driven by a servo machine. A spring device is used at the connection between the fish tail's balance follow-up system and the fish body, so that the fish tail is in an unstable balance follow-up state. The swing range of the middle section of the robot fish is controlled by the remote control, which drives the fish tail to swing and push the robot fish forward, and the middle section servo controls the steering of the fish. The appearance of the present invention is similar to that of a real fish, and the undulating advance of the fish can be realized, and the turning of the robot fish can be realized by using the reverse thrust of the water flow on the pelvic fin of the robot fish and the swing of the tail of the robot fish to one side, and can better carry out the hydrodynamic research of the fish .

Description

technical field [0001] The invention relates to a robot device, in particular to a robot fish, which is used for researching and developing a new type of high-speed, low-noise, maneuverable soft-body submersible, which can also be used as a toy or collectible, and belongs to the technical field of bionic robots. Background technique [0002] Fish—although far slower than propeller-driven boats in a straight line—are unparalleled in speed when they turn sharply and with zero acceleration. When fish accelerate from a static state, they can reach 10G at the fastest, which is equivalent to three times the speed of the space shuttle; as for the space required for high-speed sharp turns, it is less than half of the body length. Their ability to use and exert their own energy far surpasses any man-made ships. Aquatic animals must possess two abilities: (1) move faster and more sensitively than predators and food; (2) be able to move long distances before finding food. Existing aq...
