Abstract: A visible light communication method transmits a signal by visible light communication. The visible light communication method includes modulating the signal into a predetermined blinking pattern, and transmitting the signal by causing visible light to blink according to the predetermined blinking pattern and toward a wall, from a projector disposed in an indoor space surrounded by the wall. The visible light communication method also includes projecting video from the projector toward the wall, wherein the visible light is reflected by the wall to prevent the signal from being received outside of the indoor space, and the signal is used to transmit data related to the video projected to a terminal in the indoor space.

Abstract: A system includes an unmanned transport vehicle, a first winch (a winder) capable of reeling out and in a wire, a package carriage connected to the wire for putting a package transported by the unmanned transport vehicle into, and a controller. The package carriage includes an attitude control device that rotates around a rotary shaft extending in the vertical direction.
