Claim 10:
11. An automated storage and retrieval system comprising a three-dimensional grid and at least one container handling vehicle according to claim 1, the grid comprises a rail system, on which the container handling vehicle may move, and a plurality of stacks of storage containers;
the rail system comprises a first set of parallel tracks arranged in a horizontal plane and extending in an X direction, and a second set of parallel tracks arranged in the horizontal plane and extending in a Y direction which is orthogonal to the X direction, wherein the first and second sets of tracks form a grid pattern in the horizontal plane comprising a plurality of adjacent grid cells, each grid cell comprising a grid opening defined by a pair of opposed tracks of the first set of tracks and a pair of opposed tracks of the second set of tracks;
the plurality of stacks of storage containers are arranged in storage columns located beneath the rail system, wherein each storage column is located vertically below a grid opening;
the first footprint is substantially equal to a grid cell defined by a cross-sectional area, including width of the tracks, between a pair of opposed tracks of the first set of tracks and a pair of opposed tracks of the second set of tracks, and the second section extends partially into a neighboring grid opening when the first section is positioned over an adjacent grid opening.
