Abstract: In one embodiment, an inventory storage module has first to fourth conveyor segments that define a closed conveying loop in a horizontal plane. The storage module can translate inventory carriers around the closed loop until a desired one of the inventory carriers is presented at one end of the module. The first conveyor segment translates inventory carriers along a first longitudinal direction. The second conveyor segment is offset from the first segment along a first lateral direction and translates inventory carriers along a second longitudinal direction, opposite the first longitudinal direction. The third conveyor segment translates inventory carriers from the first conveyor to the second segment along a first lateral direction at a second end of the module. The fourth conveyor segment translates inventory carriers from the second segment to the first segment along a second lateral direction, opposite the first lateral direction, at a first end of the module.
