Abstract: 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.

Abstract: An automated robotic replenishment system is described. In an example implementation, the system may include containers adapted to hold items; container transportation devices adapted to transport the containers to a replenishment station; and the replenishment station. The replenishment station may include a container receiving area, a mobile storage unit receiving space, and a robotic arm, which may pick up items from the container in the container receiving area and place the item into a mobile storage unit in the mobile storage unit receiving space. The system may also include an automated guided vehicle that transports the mobile storage unit between the replenishment station and a storage area of a fulfillment center.

Abstract: A system-directed single line pick batching is described. In an example implementation, the system may receive data describing a set of orders including SKU identifiers associated with items in the orders, identify an eligible cart, and assign a location to a task queue of the cart based on the location being associated with a particular SKU identifier. In some instances, the location or SKU identifier may be determined based on an order with a certain quantity of different SKU identifiers. In some instances, the system may navigate the cart to the location and instruct the item to be picked from the location. In response to completion of the pick of the item, the system may navigate the cart to an end point.
