Problems solved by technology

The length ratio of the dolphin head to the dolphin body is about 1:1, and its propulsion is mainly generated by the elastic dolphin body in the rear half, which makes the turning radius of the intelligent bionic machine dolphin larger and the centripetal force smaller, reducing the dolphin's swimming performance and mobility

Embodiment Construction

[0030] The specific embodiments of the present invention will be described below mainly in conjunction with the accompanying drawings.

[0031] see Figure 1 to Figure 3 , the intelligent bionic robot dolphin 100 of Embodiment 1 is designed according to the model of the trevally family with a higher propulsion efficiency and propulsion speed plus a crescent-shaped tail fin, which includes a dolphin head 110, two pectoral fin mechanisms 120, a first elastic connector 130, Turning mechanism 140 , dolphin body 150 , sinusoidal propulsion mechanism 160 , second elastic connector 170 and tail fin mechanism 180 . Two pectoral fin mechanisms 120 are symmetrically arranged on both sides of the dolphin's head 110 . Two ends of the first elastic connecting member 130 are respectively fixedly connected to the dolphin head 110 and the dolphin body 150 . Two ends of the second elastic connecting member 170 are respectively fixedly connected to the dolphin body 150 and the tail fin mechan...

Abstract

The invention relates to an intelligent biomimetic robotic dolphin comprising a dolphin head, a dolphin body, a tail fin mechanism, a first elastic connecting member and a second elastic connecting member, wherein two ends of the first elastic connecting member are respectively fixedly connected with the dolphin head and the dolphin body and two ends of the second elastic connecting member are respectively fixedly connected with the dolphin body and the tail fin mechanism. In the intelligent biomimetic robotic dolphin, the first elastic connecting member is adopted to be fixedly connected between the dolphin head and the dolphin body so as to form a first flexible joint multi-joint; the second elastic connecting member is fixedly connected between the dolphin body and the tail fin mechanism so as to form a second flexible joint. A plurality of flexible joints are adopted to ensure that the turn radius decreases when the intelligent biomimetic robotic dolphin moves, therefore, the centripetal force when the intelligent biomimetic robotic dolphin moves is increased and the swimming performance and mobility of the intelligent biomimetic robotic dolphin are enhanced.

Description

【Technical field】 [0001] The invention relates to an intelligent machine, in particular to an intelligent bionic machine dolphin. 【Background technique】 [0002] After a long period of evolution, cetaceans and fishes have shown extraordinary ability to move in water. Compared with fish, dolphins are particularly outstanding in terms of swimming performance, flexibility, sonar detection and drag reduction mechanisms. Simulating the dorsal-ventral movement mechanism of dolphins to develop a new underwater navigation system is a direction for the development of miniature intelligent submarines and underwater robots. [0003] Internationally, from the perspective of robotics, the Massachusetts Institute of Technology (MIT) took the lead in developing the world's first truly bionic tuna RoboTuna in 1994. Japan developed an autonomously driven intelligent bionic robot dolphin in 1999, which is a simplified model of a high-speed swimming marine creature dolphin. Domestic researc...
