How Robots and Mobile Shelves Fulfill Orders in Warehouses
Target's patent describes an automated warehouse system where mobile robots bring shelves and shipping containers to a central robot that picks items directly into orders, all without human hands.
Original patent title: “Warehousing and order fulfillment systems and methods”
Target's patent describes an automated warehouse system where mobile robots bring shelves and shipping containers to a central robot that picks items directly into orders, all without human hands. Granted to Target Brands in 2021 with 21 claims and 1 forward citation, and it is expected to expire in 2038.
Coverage
What does this patent actually cover?
The patent describes an order fulfillment system that uses robots to move inventory and assemble orders. A control system, upon receiving an order, directs a "first mobile robot" to pick up a "mobile storage unit" (like a portable shelf) containing the desired item (a "sellable unit"). Simultaneously, a "second mobile robot" brings an "outbound container" (like a shipping box) to a "robotic picking cell." The key mechanism is that a "picking robot" within this cell transfers the item from the mobile storage unit directly into the outbound container while both the storage unit and the container remain engaged with their respective mobile robots. For example, if you order a specific toy, a robot brings the shelf with the toy, another robot brings your shipping box, and a third robot picks the toy from the shelf into your box.
The gap
What does this patent NOT cover?
- Systems where items are picked by humans instead of a robotic picking cell.
- Systems where the mobile storage unit or outbound container are detached from their respective mobile robots before the picking robot transfers the item.
- Warehouses where mobile storage units contain multiple different types of sellable units, as each unit must contain 'one or more of a single type'.
- Systems that do not use separate mobile robots for transporting the mobile storage units and the outbound containers.
- Systems without a 'dense inventory storage system' where mobile storage units are consolidated in an area.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The noveltynoveltyThe requirement that an invention be different from anything publicly known before its priority date.Read more → lies in the specific choreography: the mobile storage unit and the outbound container are both brought to the picking robot by their own dedicated mobile robots, and the picking occurs while they remain engaged with those robots. This avoids extra steps of docking or transferring units, potentially speeding up the process.
