Library performance scaling with incremental height gradient robotics

A method in a storage library comprising a plurality of rows of storage cells and a plurality of robots on guide rails, wherein the robots have picker mechanisms that can manipulate items in the storage cells, and displacement mechanisms that allow the pickers to move between rows of storage cells, wherein the robots can pass each other, the method comprising:

• configuring the displacement mechanisms on the robots to allow the picker mechanisms to access a plurality of storage cell rows, wherein each robot covers specified rows of storage cells exclusive of the other robots.
