Abstract: Being unable to restart when it collides with an object or crashes, an unmanned aerial vehicle, control system thereof and control program, for preventing damage caused by uncontrollable restarts and crashes is provided. The unmanned aerial vehicle includes a plurality of rotating bodies, a plurality of motors individually driving and rotating the plurality of rotating bodies, and a flight controller individually controlling the plurality of motors. The flight controller includes a collision/crash detection unit detecting collision or crash on the basis of a signal from a sensor, and a power cut-off command unit cutting off a power supply on the basis of a detection signal from the collision/crash detection unit.

Abstract: A drone (an aerial vehicle), able to maintain improved safety for operation by non-specialists, is provided. A farm field data stored in a cloud at take-off is compared to an environment data read by a sensor, and a control to prohibit take-off is performed if any danger is considered. In particular, it is desirable to prohibit if there is a traffic, where people and cars may pass, between the farm field and a current location, and if a direction of the drone, installed, does not point to a direction of an intrusion pathway to the target farm field. Furthermore, it is desirable to prohibit take-off if a predetermined maintenance is not performed by referring to a maintenance history.

Abstract: Provide is an agricultural chemical spraying drone with improved safety. An acceleration sensor and a contact detection sensor are combined to detect contact of a drone with an obstacle. In a case where the contact is detected, a retreat action such as hovering is taken. In addition, a message may be displayed on a control terminal, a warning sound may be generated, and a warning light may be turned on. Further, a structure capable of minimizing finger insertion accidents and minimizing interference with a rotor even in collision is adopted as a propeller guard.

Abstract: In a battery mounting unit to/from which a battery device is attachable and detachable, a configuration that enables easy attachment and detachment of the battery device having various shapes is obtained. A battery mounting unit 1 includes: connection terminals 13 configured to fit to external terminals 110 of a battery device 3 and having a shape along which the external terminals 110 are slidable at least in one direction; and a lever 30 rotatable about a fulcrum and located at a side at which the connection terminals 13 are located when seen from the battery device 3 in a state where the external terminals 110 are fitted to the connection terminals 13. The external terminals 110 are configured to be elastically deformable to fit to the connection terminals 13 by sandwiching the connection terminals 13 therein.

Abstract: The present invention provides a simple method and apparatus capable of accurately measuring the water depth of a field, in particular, the whole field. SOLUTION: An ultrasonic transmitter/receiver and a drone equipped with an infrared transmitter/receiver or a microwave transmitter/receiver are allowed to fly over the field, and the distance between the ultrasonic wave surface reflection and the microwave or infrared ground reflection. Measure the water depth just below the drone from the difference in measurement. By flying the drone all over the field, the water depth of the entire field can be accurately measured. The measurement is preferably performed only while the drone is flying at a predetermined speed or higher.

Abstract: PROBLEM: To provide a chemical spraying drone (unmanned air vehicle) in which minimizes chemical drift outside the field by a simple structure without additional equipment and complicated control. SOLUTION: To provide a chemical spraying drone that actively uses the air flow made by rotors for spraying, comprising chemical spray nozzles and rotors (preferably two-stage rotors), wherein the chemical spray nozzles are positioned under the rotors and under a circular area with its center at a point offset by a predetermined distance rearward with respect to the flying direction from the rotor's rotation axis, its radius 90 percent of the radius of the rotor blade, on a straight line with a depression angle of about 60 degrees rearward from the horizontal line passing through the rotor's rotation axis. The position of the chemical spray nozzles may be dynamically adjusted.
