UNDERWATER VEHICLE

WIPO Patent Application WO/2023/102775

A1

Embodiments of the present disclosure provide an underwater vehicle, comprising an elongated body portion, two undulating fin portions, and two driving portions. The two undulating fin portions are symmetrically arranged on two sides of the main body portion; the main body portion comprises a plurality of main body units connected in sequence; every two adjacent main body units are connected by a connector; the two driving portions are respectively located on two sides of the interior of the main body portion; each of the driving portions is configured to drive movement of the undulating fin portion on one side. In the embodiments of the present disclosure, the main body portion allows appropriate deformation and bending, so that the vehicle can better adapt to a complex working environment; vertical translation and fluctuation are realized by adopting the structure of the double-layer undulating fin, and compared with other single-fin-surface lateral flapping, lateral energy dissipation is reduced, and more energy is saved; moreover, the single side of the vehicle is controlled by the corresponding driving portion, so that high maneuverability control of the vehicle can be realized by adjusting, for example, the rotating speed and the rotating direction of a motor.
