An automatic positioning system for a commodity carriage in an automatic storage system includes shelves arranged to have commodity storage positions extending in the vertical and horizontal direction and a commodity carriage adapted to access each of the storage positions. Code marks identify each of the storage positions and a first group code scanning device, responsive to the code marks, detects groups of N adjacent storage positions and slows the movement of the commodity carriage in response thereto. N individual code scanning devices, responsive to the code marks, detect individual storage positions and the commodity carriage is stopped in response to the outputs of the group and individual scanning devices.
