Of the type capable of being combined side by side with other similar units and compose an installation for storage, movement and dispatching of several volumes which can be packaged in boxes which are stacked on each module, each base comprising a structural module (1) with three functional sections that constitute real pavements, one lower (2) referred as ground floor, one intermediate defined as first floor (3) and one upper defined as support level (4), the latter has support locks (5) for the stacked boxes (6); each one of the two pavements (2and 3) are equally provide with four rails segments (7) and (8), on which work at least one movement robot (10) and one lifting robot (9); all this set is combined with other equal units fitted on all or any of its four sides, this combination also coincides with the alignment between all the rails (7) and (8) by configuring paths in the four directions of each structural module and which constitutes routes for the robots (9 and 10); said robots combine to remove the boxes (6) from each stack to place it on another base or to send it in anywhere point of the perimeter of the installation for dispatch.
