Abstract

The invention discloses a bionic robot fish. The bionic robot fish comprises a fish head and a fish body connected with the fish head, wherein the fish body comprises a trunk skeleton and a tail skeleton connected with the trunk skeleton; the trunk skeleton comprises a plurality of trunk joints which are hinged together to form the trunk skeleton; the tail skeleton comprises a plurality of tail joints which are hinged together to form a fish tail; the fish body further comprises an elastic element and a plurality of convex pieces; the convex pieces are provided with through holes; the plurality of convex pieces are distributed on the trunk joint and the tail joint; and the elastic element penetrates through the through holes and is fixed with the trunk skeleton and the tail skeleton respectively. According to the bionic robot fish, the fish body is simple in structure and the elastic element is arranged on the fish body so that the flexibility of the fish body in a swinging process is enhanced, and the bionic robot fish has 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 ...
