Abstract: In an unmanned carrier (100) including a grating-shaped bumper (10) having elasticity and an LRF (15) having a light-emitting unit and a light-receiving unit, a common processing system performs first detection processing that detects existence of an obstruction based on light applied from the light-emitting unit to a surrounding irradiated object and reflected from the irradiated object and second detection processing that detects contact of the obstruction with the unmanned carrier (100) by determining, based on light applied from the light-emitting unit to the grating-shaped bumper (10) and reflected from the grating-shaped bumper (10), presence or absence of deformation of the grating-shaped bumper (10).

Abstract: In order to realize an autonomous mobile device which is compact and inexpensive and which is capable of almost simultaneously detecting (i) an obstacle present ahead of the autonomous moving device and (ii) a difference in level of a floor surface, an autonomous mobile device (1) of the present invention is an autonomous mobile device (1) which moves while detecting (i) an obstacle present ahead of the autonomous mobile device (1) and (ii) a difference in level of a floor surface, including: a laser range finder (21) which measures a distance to an object present in a scan area by scanning the scan area while emitting a laser beam in parallel to the floor surface; and mirrors (22a, 22b) each of which is provided within the scan area scanned by the laser range finder (21) and each of which reflects part of the laser beam to the floor surface.
