Water-air amphibious robot and operation method

The invention provides a water-air amphibious robot and an operation method, and relates to the technical field of water-air amphibious robots. The water-air amphibious robot comprises a robot body, a main propelling unit, a propelling snorkeling unit and a swing mechanism. According to the water-air amphibious robot and the operation method, the water-air amphibious robot can glide in water or fly in the air, the carrying capacity of the water-air amphibious robot is large, and the water-air amphibious robot is convenient to glide and fly; by arranging the main propelling unit, the propelling snorkeling unit and the matching mechanism, the propelling directions of the main propelling unit and the propelling snorkeling unit can be changed, so that the swimming or flying attitude of the fuselage can be flexibly changed; meanwhile, the buoyancy center or gravity center position of the fuselage can be changed through the propelling snorkeling unit, so that the swimming or flying attitude of the fuselage can be m
