    Abstract: A system for transporting inventory items includes an inventory holder and a mobile drive unit. The inventory holder has a frame with device openings. The mobile drive unit is operable to dock with an inventory holder and undock with an inventory holder. When undocked from an inventory holder, the mobile drive unit is further operable to traverse a path from a first location to a second location. The path passes through at least a first device opening of the inventory holder such that the mobile drive unit passes beneath the inventory holder while moving along the path.

    Abstract: A system includes a first mobile drive unit and a second mobile drive unit. The system also includes a first inventory holder, a second inventory holder, and a third inventory holder. An inventory station includes a first location and a second location and the inventory station operable to receive a first inventory item from the first inventory holder at the first location. The first inventory holder is transported by the first mobile drive unit. The inventory station is also operable to receive a second inventory item from the second inventory holder at the first location. The second inventory holder is transported by the second mobile drive unit. The inventory station is also operable to receive a third inventory item from the third inventory holder at the second location. The third inventory holder is fixed at the second location while the inventory station receives the first inventory item and the second inventory item.

    Abstract: A method for moving one or more mobile drive units within a workspace includes receiving, from a first mobile drive unit, a reservation request requesting use of a first path segment to move in a first direction. The method further includes determining that a second mobile drive unit is currently located on the first path segment and determining whether the second mobile drive unit is moving in the first direction. Additionally, the method includes transmitting a reservation response indicating that the reservation request is denied, in response to determining that the second mobile drive unit is not moving in the first direction. The method also includes transmitting a reservation response indicating that the reservation request is granted, in response to determining that the second mobile drive unit is moving in the first direction.

    Abstract: A method for fulfilling requests in an inventory system includes receiving a request indicating an activity to be completed. The method also includes selecting a holder to fulfill the request and an inventory station at which to fulfill the request. The inventory station is associated with a queue that includes a plurality of queue spaces. The method further includes moving the selected holder from a first location to a second location remote from the selected inventory station. Additionally, the method also includes determining that a trigger event has occurred and, in response to determining that the trigger event has occurred, moving the selected holder from the second location to a queue space of a queue associated with the selected inventory station.

    Abstract: Systems and methods described herein pertain to maintaining a virtual representation of a workspace in a material handling system and updating the virtual representation without downtime. Methods described include maintaining an initial virtual representation of a material handling grid, receiving an updated virtual representation, and generating and implementing an intermediate virtual representation that does not conflict with the initial virtual representation. Methods further include, upon determining that the intermediate virtual representation is performing without conflicts, deploying the updated virtual representation to replace the intermediate virtual representation without halting operations in the workspace. Multiple intermediate virtual representations can be generated to allow for complex changes, and the deployments performed in series.
