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: 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.

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.
