    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 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 translation: 用于移动工作空间内的一个或多个移动驱动单元的方法包括从第一移动驱动单元接收请求使用第一路径段以在第一方向上移动的预留请求。 该方法还包括确定第二移动驱动单元当前位于第一路径段上并确定第二移动驱动单元是否在第一方向上移动。 另外，响应于确定第二移动驱动单元不在第一方向上移动，该方法包括发送指示预约请求被拒绝的预约响应。 响应于确定第二移动驱动单元在第一方向上移动，该方法还包括发送指示预约请求被许可的预约响应。
