An elevator drive cassette configured for use in driving the movement of an elevator car along a rail or rack, the elevator drive cassette including: a driven pinion and drive shaft configured to be driven by a drive motor associated with the elevator car; a mechanical coupling; at least one further pinion configured to be driven by the driven pinion or drive shaft via the mechanical coupling, wherein both the driven pinion and at least one further pinion are configured to engage the same rail or rack.

An advanced warehouse and logistic system that comprises autonomous mobile lift robots and a rack lattice system that has a hinged rack lattice structure and has rack rail lattice structure both of which allow multiple autonomous mobile lift robots to move independently through the rack lattice structure to move goods and load trucks and other vehicles. A first and second embodiment of the autonomous mobile lift robot of the present invention comprising a plurality of driving trains having a first gear mounted perpendicularly to a second gear and a plurality of gears and driving motors having a movable gear configured to be positioned vertically or horizontally to have the autonomous mobile lift robot be movable in an up, down, left, and right direction depending on the geometry of the rack lattice structure and on the position of the plurality of gears of autonomous mobile lift robot.
