Abstract: An unmanned aerial vehicle (UAV) includes propellers, motors configured to drive the propellers, respectively, a main body including a control device configured to control the motors, and a wireless device configured to perform at least one of transmission or reception of a signal, a package container for containing a package, and at least one float. In a case where the UAV is placed on water, buoyancy of the float and the package container prevents a surface of the water from reaching at least a height of the wireless device. The buoyancy of the package container increases with the volume of the package container.

Abstract: Provided is an aerial vehicle, including: a package carrier including a plurality of vertical members being changeable in relative positions in a horizontal direction and surrounding a package in the horizontal direction to prevent falling of the package. A plurality of rotary wings are changeable in relative positions in the horizontal direction. The relative positions of the plurality of vertical members and the relative positions of the plurality of rotary wings are changeable. The package carrier is changed in shape in the horizontal direction in accordance with the relative positions of the plurality of vertical members. The change in the relative positions of the plurality of rotary wings is in conjunction with the shape of the package carrier.
