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: The present invention provides a drone (unmanned aerial vehicle) capable of photographing a base part of the stem and a side of the leaf of the field crops for evaluating their growth status.
A camera directed backward with a depression angle of about 60 degrees is installed at the bottom of the drone. The camera is configured to capture an image of the crop temporarily knocked down by the downdraft created by the rotor of the drone. Since the base part of the stem and the side of the leaf are exposed to the sky, images can be appropriately captured. The depression angle of the camera may be automatically adjustable depending on the flight speed, wind force, and wind direction. Further, it is preferable to rotate the entire body so that the camera is always directed to backward when the drone changes flying directions.-

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: 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.
