Patent ID: 10755227

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. Methods described include maintaining the virtual representation of a material handling grid, maintaining one or more clients operable to direct movement of the plurality of drive units in the workspace; receiving an instruction to update the virtual representation of the drive-unit navigable grid including an updated virtual representation of the workspace; and querying a subset of the one or more clients to determine whether the update to the virtual representation would cause one conflicts within the workspace. Potential conflicts include, but are not limited to, “stranded” resources which are no longer positioned on the material handling grid, and/or workstations that have not yet been suspended prior to the update. Methods further include, upon determining that the updated virtual representation would not cause a conflict, deploying the updated virtual representation to replace an existing virtual representation of the workspace.
