Bionic robotic fish and fish head floating and sinking control method

Abstract

The invention discloses a biomimetic robotic fish. The biomimetic robotic fish comprises a fish head, a fish body, a floating and diving mechanism and a control system. The floating and diving mechanism comprises a first storing-discharging water tank, an air storing tank connected with the first storing-discharging water tank and an air pump, and the first storing-discharging water tank is installed in the front of the fish body. The control system comprises a microprocessor connected with the air pump and a wireless signal receiver connected with the microprocessor, the wireless signal receiver is used for receiving wireless remote control signals and sending the wireless remote control signals to the microprocessor, and when the microprocessor judges that the movement mode represented through the wireless remote control signals is the fish-head floating movement mode or the fish-head diving movement mode, the air pump is controlled to discharge gas in the first storing-discharging water tank into an air storing cylinder, or the air pump is controlled to discharge gas in the air storing cylinder into the first storing-discharging water tank. By means of the biomimetic robotic fish, fish-head floating and fish-head sinking of the biomimetic robotic fish can be conveniently achieved, and the structure is simple. The invention further relates to a fish-head floating and sinking control method of the biomimetic robotic fish.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and in particular relates to a bionic robot fish and a method for controlling the floating and sinking of a fish head. 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 ...
