Abstract: Described are systems, methods, and apparatus for managing the movement of inventory items within a materials handling facility using rollable containers and a gravity feed conveyance system. Inventory items are placed in the rollable containers and are routed to different locations within the materials handling facility along the gravity feed conveyance system, through use of gravitational forces that cause the rollable containers to roll. By using gravity to route inventory items within the materials handling facility, the energy and power requirements for the materials handling facility are reduced, which reduces overhead costs and which is better for the environment.

Abstract: Containers can be exchanged between container holders and container shuttles using an inventory conveyance system within a workspace. The container holders are configured to hold one or more containers having consolidated inventory items in high density storage. The container shuttles are also configured to hold one or more containers for performing other operations with respect to inventory items in the one or more containers. The containers are configured to hold inventory items while the inventory items move for various operations throughout the workspace and while the inventory items are stowed in high density storage in the workspace.

Abstract: Methods and apparatus for controlling the movement of portable receptacles within a materials handling facility are described. The materials handling facility utilizes at least one linear induction motor (LIM) to move the portable receptacles having conductive elements from a first location to a second location within the facility. The LIMs may be configured such that most, if not all, of the movement of the receptacles is controlled by the application of energy from the LIMs to the conductive elements of the receptacles. This energy may cause the receptacles to move from one LIM to another LIM, where each LIM in sequence can apply force to the receptacle to pass it to the next LIM in the sequence. In some implementations, the portable receptacles are configured such that at least a base portion of the receptacle includes a conductive element to interact with the LIMs, while maintaining an overall light-weight configuration.
