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: A highly safe drone is provided. A remote controller and a drone are connected to each other through a network and cooperate to operate. The drone includes a flight control unit, a flight start command reception unit receiving a flight start command from a user, a drone determination unit determining a configuration of the drone itself, an external environment determination unit determining an external environment of the drone. The drone system has a plurality of states including a takeoff diagnosis state and satisfies a condition transitioning to another state. The takeoff diagnosis state includes a drone determination state where the drone determination unit determines the configuration of the drone itself and an external environment determination state where the external environment determination unit determines the external environment. The drone system makes the drone to takeoff after transitioning to the takeoff diagnosis state upon receiving the flight start command.

Abstract: Provided are a controller for controlling a drone that performs autonomous flight under computer control and a control program that runs on a tablet terminal. On a screen of the controller or the program, map information on an agricultural field over which the drone is to fly, route information on a route along which the drone is to fly, and an emergency stop button of the drone are displayed. A button for performing fine adjustment on an altitude may be displayed. It is desirable that the emergency stop button be translucent and be displayed such that the button is superimposed on the map information. It is desirable that emergency stop be performed only when a predetermined operation is performed on the emergency stop button a predetermined number of times or more within a predetermined time period.

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: A drone system causes a plurality of drones to perform an operation in a predetermined area in a sharing manner, wherein each of the plurality of drones holds at least one decreasing factor that is to be consumed when a corresponding drone is operated, and on condition that replenishment or refreshment with the factor needs return to the takeoff-landing port, when at least one of the drones returns to the takeoff-landing port, the drone system calculates and compares a time tA and a time tB, the time tA being a time taken by the drone to be replenished or refreshed with the decreasing factor and to take off again, the time tB being a time taken to allocate all operations remaining at a time of the return to drones not having returned and cause the drones not having returned to perform all remaining operations.
