There is provided a cargo transport system including: a management device; and a plurality of automated guided vehicles. Each of the automated guided vehicles includes: a movement instruction receiving unit that receives, from the management device, a movement instruction for moving to at least one loading operation place where a loading operation of loading a cargo to be transported into the automated guided vehicle is performed or a specified position near the loading operation place; an information transmitting unit that transmits, to the management device, load information concerning a load state of the cargo loaded into the automated guided vehicle; and a traveling unit that performs automated traveling in accordance with the received movement instruction. The management device includes: a movement instruction management unit that transmits the movement instruction to each of the automated guided vehicles; a load information receiving unit; and a load amount management unit.

Cargo transport system and automated guided vehicle

There is provided a technique capable of easily realizing control to cause an autonomous travel device to perform a predetermined operation at a predetermined position on a travel route. An autonomous travel device () is an autonomous travel device that travels along a line () placed on a travel route, and includes a detecting unit (line sensor ()) that detects the line (), and a control unit that controls an operation of the autonomous travel device () on the basis of a detection result from the detecting unit. The control unit determines a width (W) of the line () on the basis of the detection result from the detecting unit. If the determined width (W) of the line () is smaller than a predetermined reference width, the control unit causes the autonomous travel device () to perform a travel operation of traveling along the line (). On the other hand, if the determined width (W) of the line () is larger than or equal to the predetermined reference width, the control unit causes the autonomous travel device () to perform a predetermined operation different from the travel operation.

Autonomous travel device and autonomous travel system

There is provided an autonomous travel system with which a travel route of an autonomous travel device can be easily set. The autonomous travel system includes an autonomous travel device (), a line () for guiding travel that is placed on a travel route traveled by the autonomous travel device (), and a marker () that is placed on the travel route. To the marker (), operation control information related to an operation of the autonomous travel device () is recorded so as to be readable. The autonomous travel device () includes a detection unit (line sensor ()) that detects the line (), an acquisition unit (detection sensor ()) that acquires the operation control information from the marker (), and a control unit () that controls an operation of the autonomous travel device () on the basis of a detection result from the detection unit and the operation control information acquired by the acquisition unit.
