Bionic robot fish and its control method for floating and diving

Abstract

The invention discloses a bionic robot fish. The bionic robot fish comprises a fish head, a fish body, a floating and submerging mechanism and a control system, wherein the control system is used for controlling the floating and the submerging mechanism to move; the floating and submerging mechanism comprises a second water storing and draining tank, an air storage tank and air pumps, wherein the air storage tank is connected with the second water storing and draining tank; the air pumps are used for controlling the air storage tank and the second water storing and draining tank to exchange air; the second water storing and draining tank is mounted in the middle part of the fish body; the control system comprises a microprocessor and a wireless signal receiver, wherein the microprocessor is connected with the air pumps; the wireless signal receiver is connected with the microprocessor; the wireless signal receiver is used for receiving a wireless remote control signal and sending the wireless remote control signal to the microprocessor; and after the movement pattern represented by the wireless remote control signal is a fish body submerging movement pattern or a fish body floating movement pattern is judged by the microprocessor, the air pump are controlled to exhaust air in the second water storing and draining tank into the air storage tank, or the air pumps are controlled to exhaust air in the air storage tank into a first water storing and draining tank. The invention also relates to a method for controlling the floating and the submerging of the fish body of the bionic robot 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 control method for floating and diving on the 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 ...
