  • Patent number: 11964402
    Abstract: In a robot control system, the operation of a mobile robot that moves autonomously inside a facility is controlled based at least on an image captured by a photographing device that photographs a blind area located at a blind angle to the mobile robot. When entry of the mobile robot into a predetermined area corresponding to the blind area is detected, the amount of information obtainable from an image captured by the photographing device is increased.
