Abstract

In some embodiments, methods and systems for fulfilling consumer orders are provided. A stocking station includes at least one robotic stocking arm configured to unload a product from a first receptacle and to place the unloaded product onto a storage shelf, and a first picking station includes a first robotic picking arm configured to pick a first product from the storage shelf and to load the first product picked from the storage shelf into a second receptacle for delivery to a consumer. An empty receptacle placement station includes at least one robotic placing arm configured to place an empty second receptacle onto a packing conveyor configured to transport the empty second receptacle toward the first picking station for loading of the first product into the empty second receptacle. An electronic inventory management device transmits a signal the empty receptacle placement station and the first robotic picking arm.
