Claim 20:
21. A grid sorter comprising a plurality of grid sorting nodes,
wherein each grid sorting node comprises a first XY-stator, a first tile assembly, and a controller,
wherein said first XY-stator comprises a first set of X-stator coils, a first set of Y-stator coils, and a first plurality of Hall sensors;
wherein said first set of X-stator coils is flush with said first set of Y-stator coils;
wherein said first XY-stator is operatively connected to said controller;
wherein said first tile assembly comprises a first plurality of tiles;
wherein said first plurality of tiles includes a first plurality of magnetic tiles and a first plurality of non-magnetic tiles; and
wherein said controller is configured to receive signals from said first plurality of Hall sensors and is configured to selectively apply currents to said first set of X-stator coils and to said first set of Y-stator coils in order to direct motion of said first tile assembly,
wherein each grid sorting node is operatively connected to one or more conveyors and at least one of said one or more conveyors is operatively connected to two of said plurality of sorting nodes, thereby forming one or more paths for carrying packages.
