A doffing apparatus can be configured to couple to an automatically guided vehicle (AGV). The doffing apparatus can comprise at least one elongate arm, each elongate arm having a proximal end, a distal end, and a length, and at least one driver, each driver being configured to move along a respective elongate arm to move a bobbin toward the distal end of the elongate arm. The doffing apparatus can further comprise at least one alignment device. The doffing apparatus can further comprise a processor, wherein the processor is configured to: receive feedback from the at least one alignment device, provide a control signal to cause the AGV to align the elongate arm with a receptacle at a loader, and move the driver a select distance along the length of the elongate arm.

A seed cart includes first and second mating frames. The hopper is mounted on the first frame for holding seed and has an outlet to discharge the seed. A conveyor is mounted on the second frame for movement between seed loading and unloading positions. A plurality of cylinders with extendible and retractable arms control the desired position of the conveyor. A plurality of load cells are mounted on the second frame and support the first frame. The weigh scales weigh the first frame, the hopper, and the seed in the hopper, without weighing the conveyor. Therefore, an accurate amount of seed can be dispensed from the hopper via the conveyor. Wheels and a hitch tongue can be detachably mounted on the second frame to convert the cart from a stationary unit to a mobile unit.

A grain cart is provided with an internal frame and a method of constructing a grain cart with an internal frame is provided. The grain cart can have a support frame, ground wheels, a hitch assembly, and a storage hopper supported on the support frame. The storage hopper can have a spine member running along the center portion, corresponding pairs of rib members connected at intervals along the spine member and a plurality of panels connected between adjacent rib members. The storage hopper can be constructed by connecting a plurality of rib members to a spine member, connecting a cross brace across corresponding pairs of rib members, inserting panels between adjacent rib members, and connecting the panels to rib members.

An automated grain unloading system includes at least one sensor and a processor. The at least one sensor is configured to detect an interface between an upper surface of a grain mound in the receiving container and an interior surface of a wall of the receiving container, at least a portion of an upper edge of the wall, and an orientation of the grain transfer element. The processor is configured to compare the detected interface and the detected portion of the upper edge to the detected orientation of the grain transfer element, and to control the operation of the grain transfer element to direct a transfer of grain from the supplying container to the receiving container based at least in part on a result of the comparison of the detected interface and the detected portion of the upper edge to the detected orientation of the grain transfer element.

A mobile fulfillment system includes a shipper system that collects and manages customer information and order data input from customers; a fulfillment platform that receives the customer information and order data from the shipper system and controls vehicle control and dispatch accordingly; and a mobile fulfillment center that includes a plurality of vehicles dispatched from the fulfillment platform and delivers products to customers and monitors delivery status according to the customer information and order data.
