Abstract: An area evaluation unit (51) acquires for each area of a plurality of areas, a predictive value of each area which is predicted to be measured when a device operates in a space that includes the plurality of areas. A building evaluation unit (52) acquires an overall predictive value which is a predictive value of the entire space calculated using a plurality of predictive values of the plurality of areas. Further, the area evaluation unit (51) evaluates the predictive value of each area, using a partial evaluation criterion which is an evaluation criterion applied to each area. Further, the building evaluation unit (52) evaluates the overall predictive value, using an overall evaluation criterion which is an evaluation criterion applied to the entire space.

Abstract: A flying device includes a propulsion unit, a restrictor and a releaser. The propulsion unit flies the flying device in air. The restrictor restricts the propulsion unit in an open state from rotating more than a predetermined angle during flight of the flying device, the propulsion unit in the open state being rotated from a closed state by the predetermined angle. The releaser releases a restriction by the restrictor.

Abstract: In automatic travel control of a flying device towards a target, when a current distance from the target is large in comparison to a prescribed distance threshold, a controller of the flying device performs velocity feedback PID control to control the flight propulsion unit of the flying device. When the current distance becomes small in comparison to the prescribed distance threshold, the controller performs a hybrid of the velocity feedback PID control and position feedback PID control to control the flight propulsion unit such that as the flying device approaches the target, the position feedback PID control becomes more dominant than the velocity PID control. The processor calculates a weighted average of the respective manipulated variables with dynamically adjusted weights to achieve the hybrid control.
