1. A robotic picking system, comprising:
a storage system comprising: two substantially perpendicular sets of rails forming a grid; and stacked containers located beneath the rails of the grid;
the storage system comprising at least one fire extinguishing robotic service device, the fire extinguishing robotic service device comprising:
a body defining containing means that contains fire extinguishing material;
two sets of wheels upon which the body is mounted, a first set of wheels engaging with at least two rails of a first set of rails, a second set of wheels engaging with at least two rails of a second set of rails, one of the first or second set of wheels independently moveable and driveable with respect to the other of the first or second set of wheels such that only one set of wheels engages with the first and second sets of rails at any one time such that movement of the fire extinguishing robotic service device along rails to a first grid point that is over a first column is achieved by driving only the set of wheels engaged with the rails; and
a spray device dispensing the fire extinguishing material from the containing means of the fire extinguishing robotic service device, wherein the spray device includes a pump that dispenses fire extinguishing material towards a second grid point such that the fire extinguishing material descends a second column of the storage system within which a fire is located, wherein the first column is adjacent the second column.
