An aerial vehicle according to the present invention includes: at least one rotor configured to generate an air flow for lifting; and at least one sound producing structure having an opening and configured to produce sound for scaring birds and animals when the air flow generated by the rotor causes air to flow into the opening.

Wildlife warning system for aerial vehicle

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.

Unmanned aerial vehicle

A gripping mechanism is attached to a mobile body to grip and convey a transportation article. The gripping mechanism includes a pinion provided to be rotatable about a rotation axis, and a first arm and a second arm disposed with the rotation axis being the center to be separated from the rotation axis by the same distance to grip the transportation article. When the pinion rotates in a predetermined direction, the first arm and the second arm move toward the rotation axis.

Gripping mechanism and transportation article conveyance device

An unmanned aerial vehicle according to an embodiment of the present invention includes: an aerial vehicle body capable of flying; a winding member provided to the aerial vehicle body and capable of winding and unwinding a linear member; an attractive member provided to an end portion of the linear member and configured to generate a magnetic attraction force between the attractive member and an attraction-responsive part that is ferromagnetic and provided to a delivery target; and a holding mechanism configured to hold the delivery target T in a state in which the attractive member and the attraction-responsive part are coupled to each other by the magnetic attraction force.

Unmanned aerial vehicle, aerial vehicle control system and transportation method

An unmanned aerial vehicle according to the present invention includes: a main body; an arm that extends from the main body to support a rotor; a first electrical conductor which is supported by the arm and to which a voltage is applied; a second electrical conductor which is supported by the arm and spaced apart from the first electrical conductor and to which a voltage lower than the voltage applied to the first electrical conductor is applied; and a controller configured to control electrical supply to the first and second electrical conductors.

Provided is an unmanned aerial vehicle including a waterproof container including: a container main body having an opening in a bottom surface defined in a landed state of the unmanned surface aerial vehicle; a waterproof door mounted to the container main body so as to open outward and close the opening; an elastic seal, which is interposed between the container main body and the waterproof door, and is configured to close the waterproof door in a liquid-tight manner; a first door-closing mechanism configured to retain a first door-closing state of the waterproof door; and a second door-closing mechanism configured to prevent movement of the waterproof door in a door-opening direction in a second door-closing state in which the waterproof door has been pushed in a direction of resisting against an elastic force of the elastic seal from the first door-closing state.

Unmanned aerial vehicle and waterproof container

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.

The unmanned flight equipment includes an aerial vehicle capable of flying in an unmanned manner; a linear member configured to be suspended from the aerial vehicle and to hold a delivery target at a lower end thereof; a contact detection unit configured to detect contact with the delivery target or contact with the linear member; and a separation unit configured to separate the delivery target or the liner member based on a detection result of the contact detection unit.

Unmanned flight equipment and delivery method

A settlement processing system S is configured to perform a settlement process for a product picked up by a user based on information for settlement of the user, when closing of a doorof a vending machineis detected after opening of the dooris detected. In addition, the settlement processing system S is configured to perform the settlement process for the product picked up by the user based on the information for settlement of the user, in a state in which the closing of the doorof the vending machineis not detected after the opening of the dooris detected, when the state in which the user has moved from the vending machineis detected.
