Abstract

The invention discloses a bionic robotic fish which comprises a fish head and a fish body connected with the fish head. The fish body comprises a trunk skeleton connected with the fish head and a tail skeleton connected with the trunk skeleton, wherein the tail skeleton comprises multiple tail joints mutually hinged together to form a fish tail, each tail joint comprises a transversely arranged first connecting piece, a second connecting piece located under the first connecting piece and a third connecting piece with two ends respectively connected with the first connecting piece and the second connecting piece, two first connecting pieces of every two adjacent tail joints are vertically distributed and are connected in a mutual contact mode, and two second connecting pieces of every two adjacent tail joints are vertically distributed and are connected in a mutual contact mode. The multiple tail joints of the tail skeleton are arranged to be U-shaped, the free ends of every two adjacent tail joints are correspondingly connected together, so that the multiple tail joints are mutually hinged and can swing, and the bionic robotic fish is simple in structure and has a vivid 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 ...
