Abstract

Embodiments of the present disclosure provide a biomimetic underwater vehicle which is mainly used in water, comprising a head portion and a body portion, wherein the head portion comprises a first housing, a motor portion is provided in the first housing, the motor portion comprises a plurality of motor assemblies; the body portion comprises a second housing, and a plurality of rotation joints corresponding to the plurality of motor assemblies are provided in the second housing; the plurality of rotation joints are sequentially connected along the length direction of the biomimetic underwater vehicle, and the rotation joint at the most downstream is connected to a tail portion, and each of the motor assemblies is connected to the corresponding rotation joint via two pull ropes and drives the rotation joint to move, and the two pull ropes are located on two sides of the body portion respectively. According to the embodiments of the present disclosure, by the corresponding arrangements of the motors located at the head portion and the rotation joints located in the middle and the transmission manner of multiple joints, on the one hand, the inertia of movement of the tail portion of the biomimetic underwater vehicle is reduced, and on the other hand, the center of gravity of the whole is moved forward so as to reduce the swinging movement of the head portion during driving of the biomimetic underwater vehicle, thereby achieving a flexible biomimetic effect and improving the propulsive performance of the biomimetic underwater vehicle.
