Abstract
An autonomous action robot includes: a sound acquisition unit that acquires an acoustic signal; a sound source localization unit that estimates a direction of a sound source with respect to the acoustic signal; a distance measurement unit that performs measurements related to distance for a predetermined range; a map information generation unit that generates two-dimensional map information and that estimates a self-location of the autonomous action robot, using information of the distance; a sound source direction determination unit that re-estimates the direction of the sound source based on the two-dimensional map information, the estimated self-location information, and the estimated sound source direction; an action generation unit that generates an action plan based on the two-dimensional map information and the sound source direction estimated by the sound source direction determination unit; and a control unit that controls the autonomous action robot according to the action plan.
