Abstract: A display apparatus (400) includes: a reception unit that receives a plurality of captured images (415a-415f); a display control unit that displays, on a display, the plurality of captured images for selection (420) by a user, as a candidate of a movement destination of a mobile apparatus; an operation input unit that receives selection of one or more captured images from among the plurality of captured images being displayed; an autonomous movement request generator that generates autonomous movement request information including information on the one or more selected captured images; and a transmission unit that transmits the autonomous movement request information that causes the mobile apparatus to autonomously move to one or more movement destinations each corresponding to an area indicated by corresponding one of the one or more selected captured images.

Abstract: A traveling body includes a range sensor and circuitry. The range sensor is disposed on a front face of the traveling body in a traveling direction in which the traveling body travels on a road surface and disposed obliquely downward at an inclination angle relative to the road surface. The circuitry determines presence of a continuous obstacle in a case where measurement results of a plurality of planes scanned by the range sensor include a plurality of feature values indicating unevenness relative to the road surface similar to each other. The circuitry generates an obstacle map of a front region of the traveling body not scanned by the range sensor, based on sequential feature information indicating that a predetermined number of feature values indicating the unevenness are sequentially present and controls the traveling body to travel on the road surface based on the obstacle map.
