Abstract
In one embodiment, an inventory storage module has a plurality of conveyor segments that define a movement path that has a closed shape, and at least one actuator that can move inventory storage containers along the movement path. Each actuator has a roller having a cylindrical body that has a first end, a second end that are offset from the first end along a central axis, and a cylindrical outer surface that extends from the first end to the second end. Each actuator has a helical track disposed around the cylindrical outer surface in a helical pattern. Further, each actuator has at least one track follower that can ride along the helical track when the roller is rotated about the central axis so as to move the inventory storage containers along an axial direction that is substantially parallel to the central axis.
