Abstract: A system of inventory management is described. It includes at least one container adapted to hold inventory items. A conveyor system is adapted to move the containers to and from pick cells. Each pick cell contains an array of processing locations designed to receive containers and an inventory movement tool such as a robotic arm designed to interact with containers received by the pick cell. The pick cells include at least one buffer shelf for processing items.

Abstract: A system of exchanging information between machines is described. The system includes multiple communication modules with at least an infrared transmitter and receiver. At least one mobile robot having at least one said communication module. A receiving station communication module includes at least an opposing infrared transmitter and receiver. Each mobile robot identifies itself and communicates its intended tasks to a receiving station by sending a single pulse width encoded message. The encoding of information within the message occurs by the encoded message's timing.

Abstract: A system for moving payloads is described. It uses one or more mobile robots. Each mobile robot comprises a payload bearing platform with a transfer mechanism with multiple degrees of freedom of movement. The system includes one or more stack exchangers having a set of alignment mechanisms, and at least one payload transfer ramp. The mobile robots pass through the stack exchanger and pick up a payload or drop off a payload.

Abstract: A system for location of assets on a premises is described. The system uses identifiers attached to a group of one or more assets along with mobile sensor packages. Each mobile sensor package contains components for data processing, data exchange, and storage. The sensor package also contains a sensor for reading identifiers and a location tool. The mobile sensor packages are attached to each mover of assets on the premises.

Abstract: A system for movement of products is described. The system uses a facility which contains warehouse shelves, each shelf includes various devices to move products within the shelf. Some rollers on the shelf are active, others passive. Power is transferred to the active rollers from an end of arm tool.

Abstract: A system for moving payloads is described. It uses one or more mobile robots. Each mobile robot comprises a payload bearing platform, and a payload release latch. The system includes one or more stack exchangers having a set of alignment rails, a payload transfer ramp, and a latch engagement bar. The mobile robots pass through the stack exchanger and pick up a payload or drop off a payload without fully stopping motion.

Abstract: A method for movement of products is described. The method uses a facility which contains warehouse shelves, each shelf has a front, at least one moveable frame which travels to each shelf front to access the containers stored on each shelf. The moveable frame includes a repositionable storage ledge, a lifting device, and a gripping device. Mobile Robots exchange payloads between moveable frames.

Abstract: A system for automated management of a high density storage facility which contains shelves having multiple containers with products stored within the containers. The system comprises an autonomous mobile robot and a moveable frame. The moveable frame includes supports, horizontal and vertical members, and storage platforms. The moveable frame includes a gantry, an articulated arm with an end of arm tool, and a lifting device. Some storage shelves within the high-density storage facility include an overhead rail and the moveable frame reversibly connects to the rail and guides the moveable frame, as well as provides power to the moveable frame.
