Patent attributes
A robot apparatus includes a moving unit configured to move in a moving plane on flooring, and turn in horizontal direction of the flooring about a rotation axis vertical to the flooring; an imaging unit configured to take images in a direction horizontal to the moving plane, and rotate in horizontal direction of the flooring about the rotation axis; a storage unit configured to store the image taken by the image processor when the moving unit receives a turning request of a command angle; a detector configured to detect a rotation angle of the imaging unit relative to the moving unit; a controller configured to control a turning of the moving unit and a rotating of the imaging unit based on a common value which makes the moving unit turn in a direction of the command angle and which makes the imaging unit rotate in an opposite direction, and based on a rate value which changes turning of the moving unit or rotating of the imaging unit so as to compensate a gap determined by comparing the taken image with the stored image; and a stop unit configured to stop the turning of the moving unit and the rotating of the imaging unit, when the command angle corresponds to the rotation angle detected by the detector.
