Underwater robot and control method therefor

An underwater robot comprising:

• a robot main body including a front end, wherein a dirt suction port is provided at a bottom of the robot main body, a first water outlet is provided on a top of the robot main body, the first water outlet is in communication with the dirt suction port, a second water outlet is further provided at the bottom of the robot main body, the second water outlet is in communication with the first water outlet, and the second water outlet is located on a side of the dirt suction port close to the front end;
• and
• a water-pumping mechanism and an escape mechanism provided in the robot main body, wherein
• in a first state, the underwater robot is configured to control water stream to flow into the underwater robot from the dirt suction port and to discharge out of the underwater robot via the first water outlet, the water-pumping mechanism is switched on, and the escape mechanism is switched off;
• in a second state, the underwater robot is configured to control water stream to flow into the underwater robot from the first discharge port and to discharge out of the underwater robot via the second water outlet, the water-pumping mechanism is switched off, and the escape mechanism is switched on, so as to lift the front end of the robot main body to a preset angle by the water stream discharged via the second water outlet.
