Mobiles, exploration surveyors and exploration survey methods

摘要

To provide a movable body movable in air and on the water and to easily perform investigation and survey about a water area and a land around the water area.SOLUTION: A movable body (an investigation and survey apparatus 10) enables aerial flight and waterborne navigation. It includes a body 50, a float 58 attached to a lower part of the body 50 to float on the water, and a propulsion force source (rotary vanes 40) attached around the body 50 to generate propulsion force for aerial flight and waterborne navigation. The propulsion force source (rotary vanes 40) includes a one side rotary vane (a rear rotary vane 40b) arranged at one side of the body 50 in a front-rear direction, and the one side rotary vane (the rear rotary vane 40b) rotates with a shaft extending in a lateral width direction of the body 50 as a center, and the rotary vane is settable to a horizontal direction directed to a vertical direction and to a vertical direction directed to a front-rear direction.SELECTED DRAWING: Figure 5
