bionic robot fish

Abstract

The invention discloses a bionic robotic fish. A fish body of the bionic robotic fish comprises a body skeleton and a tail skeleton. The body skeleton comprises multiple body joints hinged to one another. The tail skeleton comprises multiple tail joints hinged to one another. The fish body is provided with at least two fish body swing devices. Each fish body swing device comprises a fish body swing motor, a rope winding wheel and a pull rope twined around the rope winding wheel. Rotary shaft parts of the fish body swing motors are sleeved with the rope winding wheels. The two ends of each pull rope extend outwards from the corresponding rope winding wheel. The fish body swing motors are installed in the body joints of the body skeleton. The two ends of the pull rope corresponding to each fish body swing motor extend forwards or backwards at the same time in the arrangement direction of the multiple body joints, sequentially penetrate the multiple body joints and then are fixed to the body joint located at the foremost end or the backmost end or extend backwards at the same time in the arrangement direction of the multiple tail joints, sequentially penetrate the multiple tail joints and then are fixed to the tail joint located at the backmost end.

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 ...
