  "abstract": "A robotic picking system which does not require grid area to be reserved for picking stations and which enables efficient automated picking. There is provided a storage system including a first set of tracks extending in a first direction, a second set of tracks extending in a second direction transverse to the first direction, to form a grid comprising a plurality of grid cells, a framework structure on which the first set of tracks and the second set of tracks are received such that a stack of containers may be stored below the plurality of grid cells, a plurality of load-handling devices for lifting and moving containers stacked in stacks within the storage system, each of the load-handling devices being configured to move on the tracks above the stacks of containers at the top level of the grid.",
