Bionic robot fish

Abstract

The invention discloses a bionic robot fish. The bionic robot fish comprises a fish body, wherein the fish body comprises a trunk framework and a tail framework, wherein the trunk framework comprises a plurality of trunk joints which are integrally hinged to each other to form the trunk framework; the tail framework comprises a plurality of tail joints which are integrally hinged to each other to form a fish tail part; the tail joint positioned at the front end is connected with the trunk joint positioned at the rear end; at least two fish body swinging devices are arranged on the fish body, and are separately used for driving the trunk framework and the tail framework to swing; each of the fish body swinging device comprises a fish body swinging motor, wherein each of the fish body swinging motors is mounted in the corresponding trunk joint of the trunk framework; fish body position detecting devices are also mounted on the fish body; and the fish body position detecting devices and the fish body swinging devices are in one-to-one correspondence, and are separately used for detecting the position of the tail framework and the position of the trunk framework, producing corresponding position signals and sending the corresponding position signals to a control system of the bionic robot fish, and the control system controls the actuating of the fish body swinging motors according to the received position signals.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and in particular relates to a bionic robot fish. Background technique [0002] Before the 1990s, the research on fish bionics mainly focused on the theoretical aspects. With the deepening of the research on the propulsion mechanism of fish and the new development of robotics, bionics, electronic technology, material science and control technology, the simulation of fish swimming A new type of underwater robot based on its dynamic mechanism—the bionic robot fish has received widespread attention at home and abroad. According to the proposed "jet propulsion theory" of fish tail propulsion, the United States Institute of Technology developed a 1.2-meter-long bionic tuna and a 0.8-meter-long bionic barracuda. The Marine Science Center of Northeastern University in the United States has developed a wave-propelled robotic eel using shape memory alloys and linkage mechanisms. The University of ...

Problems solved by technology

[0003] However, at present, the structure of the bionic robot fish body at home and abroad is complicated, and the swing range of the fish body cannot be accurately positioned, and the manufacturing cost is high.
