[0048] The use process of the application is as follows:

[0049] External perception: a control circuit board 203 perceives the external space of the robot and the posture of the robot itself through a perception device electrically connected with the control circuit board 203, and the perception device comprises a gyroscope 205, a pressure gauge 206, a camera and a sonar.

[0050] Power driving: the control circuit board 203 drives the first driving device 3 and the second driving device 4 to work according to the perceived external space and the posture of the robot itself, so as to provide kinetic energy for the movement of the robot.

[0051] First driving device 3 operation: the control circuit board 203 controls a power supply 204 to provide periodic electric energy for double-path shape memory alloy wires on a first telescopic pipe 301, so that the temperature of the double-path shape memory alloy wires changes periodically, and then the shape of the double-path shape memory alloy wires changes periodically, the periodic change of the shape of the double-path shape memory alloy wires on the first telescopic pipe 301 drives the first telescopic pipe 301 to periodically expand and contract, when the first telescopic pipe 301 expands and causes the volume of the internal cavity of the first telescopic pipe 301 to increase, the control circuit board 203 synchronously controls a first electromagnetic valve 302 to open, the first electromagnetic valve 302 absorbs water to drive the robot to move forward, when the first telescopic pipe 301 contracts and causes the volume of the internal cavity of the first telescopic pipe 301 to decrease, the control circuit board 203 synchronously controls the first electromagnetic valve 302 to close, the water in the internal cavity of the first telescopic pipe 301 flows into the internal cavity of a second telescopic pipe 401 through the internal cavity of the fixed shell 1 and is sprayed out from a second electromagnetic valve 402;

[0052] The second driving device 4 works: the control circuit board 203 controls the second telescopic pipe 401 and the first telescopic pipe 301 to work synchronously, and when the second telescopic pipe 401 extends to cause the volume of the internal chamber to increase, the control circuit board 203 controls the second electromagnetic valve 402 to close synchronously, and when the second telescopic pipe 401 retracts to cause the volume of the internal chamber to decrease, the control circuit board 203 controls the second electromagnetic valve 402 to open synchronously.

[0053] The above-mentioned working mode of the first driving device 3 and the second driving device 4 makes the robot move in the direction of the first driving device 3 underwater, but the first electromagnetic valve 302 and the second electromagnetic valve 402 both have the functions of water spraying and water suction, so when the robot needs to move in the direction of the second driving device 4 underwater, the control circuit board 203 only needs to control the first electromagnetic valve 302 to open when it is closed, and to close when it is opened, and the second electromagnetic valve 402 also needs to be operated reversely synchronously.

[0054] Posture adjustment: the control circuit board 203 controls the motor to work, the motor works and changes the angle of the fin-shaped sheet 501 through the transmission device, thereby changing the posture of the robot.
