Abstract: An adjustable rack assembly includes a base frame defining an upper end and an open front side and an extension frame defining an upper end, a bottom end and an open front side. The extension frame is slidably mounted to the base frame. The assembly further includes an actuator coupled between the base frame and the extension frame and operable to move the extension frame between a collapsed position and an extended position. A compartment unit is supported by the extension frame and is at least partially collapsible to accommodate the movement of the extension frame between the collapsed position and the extended position.

Abstract: In an infrastructure that uses a mobile order fulfillment system, robotic drive units may be dispatched and instructed to bring inventory holders to a workstation where at least one of the inventory holders is packed and prepared for shipment. The robotic drive units are then instructed to move the prepared inventory holder to a transport vehicle such as a truck. Fiducial marks may be removably placed within the transport vehicle to aid navigation of the robotic drive units. At a destination facility, additional robotic drive units may be instructed to move the inventory holders from the truck and place the inventory holders at appropriate storage locations.

Abstract: A method for managing an inventory system includes receiving an operation request that identifies an inventory item and selecting, from a plurality of workstations, a workstation at which to fulfill the operation request. The method also includes moving an inventory holder storing the identified inventory item to the selected workstation and moving a supply holder storing a supply item associated with the received operation request to the selected workstation. The method additionally includes fulfilling the operation request, at least in part, at the workstation.

Abstract: A method for transporting inventory items includes moving a mobile drive unit to a first point within a workspace. The first point is a location of an inventory holder. The method further includes docking the mobile drive unit with the inventory holder and moving the mobile drive unit and the inventory holder to a second point within the workspace. The second point is associated with conveyance equipment. The method further includes moving the inventory holder to a third point within the workspace using the conveyance equipment.

Abstract: A robotic carton unloader for unloading a carton pile resting on a floor includes a mobile body movable across the floor on more than one wheel. A conveyor system mounted on the mobile body conveys unloaded cartons thereon. A robotic arm assembly has a manipulator head attached to a front end of the upper arm assembly. The manipulator head engages at least one carton at a time from a carton pile resting on a floor for movement to the conveyor system. A built-in jacking apparatus is extendable from the mobile body to a floor to raise the mobile body a distance sufficient to raise at least one of the more than one wheel away from contacting the floor.

Abstract: A method and apparatus for supplying a unit of work in a material-handling process includes a set-point of work units desired at a material-processing station and an actual measure of work units at the material-processing station. A feedback control algorithm is performed to establish the set point of work units at the material-processing station and an error between the work units at the material-processing station and the set-point of work units at the material-processing station. The feedback control algorithm also determines a desired amount of units that should be supplied to the material-processing station as a function of the error. The feedback control algorithm causes a work unit to be released from the inventory store for a particular processing station when the actual amount of work units supplied to that processing station is less than the amount of work units that should be supplied to that processing station.

Abstract: A warehouse automation system adapted to improve warehouse operating productivity includes a plurality of carts for transporting products within a warehouse and a controller. The controller is adapted to associate a first one of the plurality of carts with a first person and to control the first cart to lead the first person around the warehouse. According to one advantage, the time the first person spends restocking, picking, counting, sorting, moving, and packing product into customer orders and shipments, for example, is reduced.

Abstract: The present invention relates to an apparatus for transferring electronic devices from a holding unit to a processing station. The apparatus comprises first and second rotating mechanisms having a plurality of handlers and a plurality of holders respectively, an imaging mechanism, a processor and an adjusting mechanism. In use, a handler retrieves an electronic device from the holding unit and moves the device to a transfer position. A holder retrieves the electronic device from the handler at the transfer position and transfers the electronic device to the processing station. Prior to this retrieval, the adjusting mechanism adjusts a relative position between the holder and the handler at the transfer position. This adjustment is based on offsets calculated by the processor using images of the handler and holder captured by the imaging mechanism. The adjustment allows the electronic device to be retrieved more securely by the holder.

Abstract: A sorting system and method. A method includes receiving a plurality of items to be sorted. The method includes assigning a sort criterion to each of a plurality of bins and measuring and storing at least a thickness of each of the items. The method includes assigning each of the items to a bin based on the sort criterion assigned to the respective bins. The method includes transporting each of the items to a respective bin based on the assignments. The method includes determining that the items being transported to a first bin will cause the first bin to reach a capacity threshold based on the stored thicknesses or volume of the items being transported to the first bin. The method includes, in response to determining that the items being transported to the first bin will cause the first bin to reach the capacity threshold, assigning the first criterion to a second bin.
