Floating and sinking mechanism of bionic robot fish

Abstract

The invention discloses a floating and sinking mechanism of a bionic robot fish. The floating and sinking mechanism of the bionic robot fish comprises a first water storage and drainage tank, a second water storage and drainage tank, a gas storage tank and an air pump, wherein the first water storage and drainage tank is used for controlling a fish head to float and sink, the second water storage and drainage tank is used for controlling a fish body to float and sink, the gas storage tank is connected with the first water storage and drainage tank and the second water storage and drainage tank, and the air pump is used for controlling gas exchange to be conducted between the gas storage tank and the second water storage and drainage tank as well as between the gas storage tank and the first water storage and drainage tank; and the first water storage and drainage tank is mounted on the front portion of the fish body, and the second water storage and drainage tank is mounted on the middle portion of the fish body. According to the floating and sinking mechanism of the bionic robot fish, the first water storage and drainage tank and the second water storage and drainage tank are arranged on the front portion and the middle portion of the fish body and connected with the gas storage tank, and gas delivery between the gas storage tank and the first water storage and drainage tank as well as between the gas storage tank and the second water storage and drainage tank is controlled through the air pump, so that water storage and drainage of the first water storage and drainage tank and the second water storage and drainage tank are achieved, and floating and sinking of the fish body and the fish head of the bionic robot fish are achieved accordingly; and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and in particular relates to a floating and sinking mechanism of a bionic robotic 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 l...
