Abstract: In one embodiment, an inventory storage system has a vertical stack of storage modules. Each storage module has first and second conveyor segments that carry storage containers along a longitudinal direction between first and second modules ends, and third and fourth conveyor segments that carry the containers between the first and second conveyor segments at the first and second module ends, respectively. The conveyor segments define a movement path having a closed shape, and the storage module translates the containers around the movement path until a desired one of the containers is presented at one of the first and second module ends. The system also has a multi-directional elevator having a platform. The elevator moves the platform over the vertical stack along at least one of the longitudinal direction and a lateral direction, and lowers the platform into an interior of the vertical stack.
