    摘要: A system-directed robotic cart picking system is described. In an example implementation, the system may generate a picking itinerary including pick-to-cart routing based on locations of items in an order fulfillment center and received order data identifying the items, and may transport the carts in the order fulfillment center according to the pick-to-cart routing. The system may determine a zone of the order fulfillment center to which to assign a picker based on the picking itinerary and may determine tasks, such as picking at least one item from the locations to the carts, for the picker located in the zone. In some instances, the system may output pick instructions to a picker client device directing the picker to perform the tasks and may transport the carts to a defined point in the order fulfillment center in response to completion of the tasks.

    摘要: A system and method for transferring items in a storage facility are provided. The storage facility includes a storage system that includes bins, a control server, and a sensing system. A pick-put operation on an inventory item is performed by picking the inventory item from a robotic apparatus by an operator and storing the inventory item in a corresponding bin of the storage system. The control server receives sensor signals when the sensing system automatically senses a pick-up of the inventory item from the robotic apparatus and placement of the inventory item in the corresponding bin of the storage system. The reception of the sensor signals by the control server indicates execution of the pick-put operation. Thus, a need for the operator to manually scan the inventory item during the pick-up or press any buttons on the storage system to indicate completion of the pick-put operation is eliminated.

    摘要: The inventive concept provides a transfer robot system. Embodiments of the inventive concept provide a transfer robot system and a transfer robot system driving method in which a bottleneck phenomenon of mobile robots may be prevented, as a new obstacle which does not exist within a map for a mobile robot is recognized in advance during an autonomous driving of the mobile robot and the new obstacle is not passed through. The transfer robot system includes an OHT for transferring an article by autonomously driving along a rail and having a bottom side distance detection sensor installed for generating a distance information of below; and a mobile robot for transferring the article by autonomously driving on the ground and autonomously driving while avoiding an obstacle information generated through the distance information.
