Example Embodiment

[0021] The present invention will be described in detail below with reference to the drawings and embodiments.

[0022] As shown in Figure 1, the present invention includes a robotic turtle main cabin module 1, swingingly connected to the main cabin module 1 with four flipper drive modules 2 in the circumferential direction and two-by-two symmetrical structure, and each flipper drive module 2 A wing-shaped flipper 3 is rotatably connected, and a dynamic sealing mechanism is respectively arranged at each power output part of the swing connection and the rotation connection.

[0023] As shown in Figures 1 and 2, the main cabin module 1 of the present invention includes a spherical crown 101 and a cylindrical shell 102 made of transparent plexiglass, a ferrule 103 made of light aluminum alloy, and an upper ring Cover 104 and bottom cover 105. The top cover 101 and the ferrule 103 are bonded together by a waterproof sealant, the housing 102 is bonded with the upper ring cover 104 and ...

Abstract

The invention relates to a bionic robot chelonian with two-stage freedom fin. The invention comprises a main cabin module, four fin driving modules swinging connected around the main cabin module, while each driving module is rotationally connected with a wing fin, and the connection between the swing and rotation uses dynamic sealing device. The main cabin module uses a frame sealed connected by several parts, while the driving modules are two-by-two symmetry distributed around the frame. A servo motor in the main cabin module can make fins front and back to realize the first-stage freedom, and the driving motor in the find driving modules can drive the fins in second-stage freedom. The invention has stable operation and free motion or the like.

Description

technical field [0001] The invention relates to an underwater bionic robot sea turtle, in particular to a bionic robot sea turtle with a flipper mechanism with two degrees of freedom. Background technique [0002] After hundreds of millions of years of natural selection, especially heredity and variation, nature has bred a variety of organisms. In the long evolutionary process, biological populations have formed advantages and strengths in many aspects such as perception, execution, control, information processing, behavioral decision-making, and organizational coordination to adapt to the environment. Long-standing studies of the kinematics and hydrodynamics of animal swimming in nature have shown that the performance of man-made underwater vehicles lags behind in efficiency and maneuverability. In the research field of underwater vehicles, the most representative is a highly streamlined body propelled by propellers. Autonomous Underwater Vehicle (AUV) using this design m...
