Intelligent underwater robot with umbilical cable based on Beidou positioning

The invention discloses a Beidou positioning-based intelligent underwater robot with an umbilical cable, and belongs to the technical field of underwater robots, the Beidou positioning-based intelligent underwater robot comprises a robot main body, longitudinal motors are fixedly connected to two sides of the robot main body, and a transverse motor is fixedly mounted on one side of the tail of the robot main body; and a plurality of tail fin modules are fixedly connected to four corners of the tail part of the robot main body. According to the underwater communication robot, free switching operation under different modes is achieved through the multifunctional control system and the upper computer. Meanwhile, the umbilical cable is arranged to be connected with the water surface communication buoy to achieve the signal strength of Beidou positioning signals and shore-based communication, the underwater communication performance of the robot body can be kept, and the underwater communication performance of the
