Claim:
A robotic storage system comprising: a first and a second robot; a first and a second mobile storage element; a shelf system wherein said first and said second mobile storage elements can be disposed; a first and a second drive adapted to be loaded with either of said mobile storage elements in an engaging relationship whereby storage related operation can occur; a queue system containing a first and a second move instruction received from a host wherein said first move instruction includes commands to move said first mobile storage element from said shelf system to said first drive and load said first mobile storage element into said first drive via said first robot, said first robot identified by the host, and said second move instruction includes commands to move said second mobile storage element from said shelf system to said second drive and load said second mobile storage element into said second drive via said first robot; a communication interface that affirms to said host that said first move instruction is completed via a first move response, that said first drive is engaged at a minimum acceptable level with said first mobile storage element via a first load response, that said second move instruction is completed via a second move response, that said second drive is engaged at said minimum acceptable level with said second mobile storage element via a second load response wherein all of said responses are made prior to actual execution of any of said responses; and an algorithm operatively regulating said queue system to reorganize said first and said second move instructions in said storage system in a preferred order and cause said first and said second robot to physically execute said instructions in said preferred order.
