    Abstract: A robotic arm for transporting products in a product storage and dispensing system is disclosed. The robotic arm broadly includes a base operable to couple the arm to the dispensing system; a sprocket coupled with the base; an extendible arm segment coupled with the base; and a chain coupled with the sprocket and the extendible arm segment such that rotation of the sprocket causes movement of the chain and extension of the extendible arm segment.
