Abstract

The invention discloses a bionic robotic fish which comprises a fish head, a fish body and a surfacing-diving mechanism, wherein the surfacing-diving mechanism comprises a first water storage drainage tank for controlling the fish head to surface or dive, a gas storage tank connected with the first water storage drainage tank, and a gas pump for controlling gas exchange between the gas storage tank and first water storage drainage tank; the first water storage drainage tank is installed on the front of the fish body. The first water storage drainage tank of the bionic robotic fish is connected with the gas storage tank, and the gas pump is utilized to control the gas transmission between the gas storage tank and first water storage drainage tank, thereby implementing water storage and drainage of the first water storage drainage tank, and further implementing surfacing and diving of the fish head of the bionic robotic fish. The bionic robotic fish is simple in structure, and has the realistic bionic effect.

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 ...
