Bionic robot fish

Abstract

The invention discloses bionic robot fish, which comprises a fish head and a fish body connected with the fish head, wherein the fish head comprises an upper jaw and a lower jaw; fish eyes are arranged on the upper jaw; the fish body comprises a body framework, a tail framework and a fish fin arranged on the body framework; the fish fin comprises a fin framework; the bionic robot fish also comprises an opening and closing mechanism, an eye part driving mechanism, a fish body swinging device, a fin part swinging device, a fin part rotating device, a floating and diving mechanism and a control system; the opening and closing mechanism is connected with the upper jaw and the lower jaw and is used for driving the upper jaw to do opening and closing action relative to the upper jaw; the eye part driving mechanism is arranged in the fish head and is used for driving the fish eyes to rotate; the fish body swinging device is arranged in the body framework and is used for driving the body framework and the tail framework to swing; the fin part swinging device is used for driving the fish fin framework to swing; the fin part rotating device is used for driving the fin framework to rotate; the floating and diving mechanism is used for driving the fish head and the fish body to float and dive; the control system is used for controlling the opening and closing mechanism, the eye part driving mechanism, the fish body swinging device, the fin part swinging device, the fin part rotating device and the floating and diving mechanism to act.

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 ...
