Unmanned aerial vehicle

An unmanned flying object comprising:

• a frame carrying a vehicle body, wherein the frame is elongated and extends in a forward direction between a front-half side of the vehicle body and a back-half side of the vehicle body;
• four rotary wings for floating the unmanned flying object which are positioned inside the frame adjacent to a corresponding set of openings provided in an upper surface and a bottom surface of the frame, wherein a plurality of sidewall openings formed in a sidewall separating the upper surface and the bottom surface of the frame are positioned adjacent to the corresponding set of openings, and wherein the four rotary wings include a first pair of rotary wings positioned in the front-half side of the vehicle body and a second pair of rotary wings is positioned in the back-half side of the vehicle body such that the first pair of rotary wings are spaced apart from the second pair of rotary wings to define an area therebetween, wherein each of the corresponding set of openings is associated with a corresponding one of the plurality of sidewall openings, and wherein a sidewall opening of the plurality of sidewall openings is positioned at a side of each of the four rotary wings;
• a driver that drives the first pair of rotary wings and the second pair of rotary wings;
• a control signal generation unit coupled to the driver and positioned in the area between the first pair of rotary wings and second pair of rotary wings, wherein the control signal generation unit generates a control signal for causing the driver to drive the first pair of rotary wings and the second pair of rotary wings,
• and wherein the first pair of the four rotary wings, the control signal generation unit, and the second pair of the four rotary wings are arranged apart from each other in the forward direction in the order of the first pair of rotary wings, the control signal generation unit, and the second pair of rotary wings,
• an inspection camera and a traveling direction shooting camera which are placed at positions on the upper surface of the vehicle body and pointed in the forward direction of travel and oriented along a longitudinal axis parallel to the elongated frame, the positions being different from each other and are located in the area between the first pair of rotary wings and second pair of rotary wings, where the inspection camera is a detachable camera positioned to limit scattered liquid from reaching a position of the inspection camera or the traveling direction shooting camera when the unmanned flying object is flying above a surface on which a liquid at least partly exists, and
• an unmanned flying object-side communicator transmitting externally traveling direction image data obtained by shooting in a traveling direction by means of the traveling direction shooting camera while the unmanned flying object is flying,
• wherein resolution of moving image or still image obtained from the traveling direction image data is lower than resolution of moving image or still image obtained from image data of the inspection camera.
