Abstract:
Disclosed herein is a human transport device and associated system to transport a user within an active workspace. The human transport device may include a platform to support a user, an enclosure coupled to the platform to surround the user, a drive subsystem to power the human transport device, and a control unit to control the movement of the human transport device in coordination with active mobile drive units moving within the workspace. A system implementing one or more human transport devices may include a management module to direct the movement of the one or more human transport devices and designate one or more areas within the workspace as protected areas. Unauthorized objects may be prohibited from entering the protected areas while the human transport device may be allowed within the protected areas.
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:
Techniques for controlling mobile drive units (e.g., robots) in proximity to humans in a physical area are described. A management device may send an activity message to the mobile drive units instructing the mobile drive units to perform a set of activities. If a human is detected in the physical area, the management device or another mobile drive unit may send an activity command instructing a mobile drive unit to stop, reduce the speed at which it is traveling, to change its path of travel, or to continue performing its set of activities. If the mobile drive units do not receive the activity command, the mobile drive units may stop performing the set of activities. After the management device determines that the human has left the physical area, the management device may resume sending the activity message.
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 may be operated upon. A random pattern or other image may be applied to a floor surface of the infrastructure, from which a map may be created that associates locations within the infrastructure to different portions of the image. A robotic drive unit may then reference the map along with images of the floor surface captured by its camera in order to determine its current location, as well as how to reach a desired destination.
Abstract:
A method for fulfilling inventory requests includes receiving an inventory request requesting an inventory item and selecting the requested inventory item from an inventory holder. The method further includes storing the requested inventory item in an order holder associated with the inventory request and moving the order holder to a storage space. In addition, the method includes detecting a triggering event and in response to detecting the triggering event, retrieving the order holder from the storage space.
Abstract:
A method for storing inventory items in an inventory system includes detecting that an inventory holder is available for storage and determining a classification of the inventory holder. The method also includes determining a classification of each of a plurality of storage locations and selecting a storage location for the inventory holder based, at least in part, on the classification of the inventory holder and the classification of the selected storage location. The method additionally includes transmitting information identifying the storage location to a mobile drive unit associated with the inventory holder.
Abstract:
Inventory systems may include one or more sensors capable of detecting spatial positioning of inventory holders and an arm of a worker interacting with the inventory holder. Data can be received from a sensor, a gesture of the arm can be determined from the data, and a bin location or other information can be determined based on the gesture.
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:
An inventory system has mobile drive units that freely and independently move about a facility to transport inventory holders. The mobile drive units may operate through communications with other drive units, or under a more centralized control of a management module. For various operating scenarios, the mobile drive units are directed to shuffle the inventory holders in a manner that minimizes travel of the mobile drive units, thereby improving overall system efficiency. One or more single mobile drive units may be used to transport inventory holders to and from a region, and to sequentially reposition or slide each of the inventory holders within the region according to a priority ordering.
Abstract:
A system includes an inventory pier, a mobile drive unit, and a management module. The inventory pier includes a defined area arranged to station an inventory holder. The inventory holder stores an inventory item. The mobile drive unit is operable to transport an order holder. The management module is operable to calculate a metric associated with demand for the inventory item. Based at least in part upon the metric, the management module is operable to select, from a plurality of inventory holders, the inventory holder storing the inventory item to be stationed at the defined area of the inventory pier. The management module is further operable to receive an order for the inventory item and instruct the mobile drive unit to transport the order holder to the inventory pier. The order holder is operable to receive the inventory item from the inventory holder proximate to the defined area.
