Abstract: Provided is an optical scanning device capable of preventing abnormal vibration occurring in a micro mirror. The optical scanning device includes a micro mirror that reflects light beams, torsion bars that rotate the micro mirror around a Y-axis, a movable frame that is disposed around the micro mirror, and meander-type piezoelectric actuators that rotate the micro mirror around an X-axis. The movable frame has a rectangular shape, and has a rib provided on the rear surface of the movable frame. Corner regions of four corners of the movable frame have a removal region where no rib is partially provided or a rib with a thickness thinner than other regions is provided.

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.

Abstract: A robot control system according to the present embodiment is a robot control system that controls a plurality of transport robots that is travelable autonomously in a facility. The robot control system: acquires error information indicating that an error has occurred in a first transport robot; acquires transported object information related to a transported object of the first transport robot; determines a second transport robot able to transport the transported object of the first transport robot among the transport robots based on the transported object information and the error information; and moves the second transport robot to a transfer location of the transported object of the first transport robot.
