Patent ID: 7815031

Claim:
A storage matrix comprising: a plurality of stationary cell modules arranged within the storage matrix, wherein the cell modules disposed along the outer rows of the matrix comprise a plurality of motors arranged along both planar axes of the storage matrix, and the cell modules disposed along the inner rows of the matrix comprise at least one metal plate and at least one motor disposed along one of the planar axes of the storage matrix; and a plurality of carriers comprising at least one magnet disposed on an underside of each of the carriers, the at least one magnet being configured to engage a motor on the inner row cell modules or the outer row cell modules, wherein the plurality of motors of each outer row cell module is configured to move the respective carrier bi-directionally within the storage matrix and is also configured to stabilize the respective carrier when the carrier is moving or at a stationary position, and the at least one motor of each inner row cell module is configured to move the respective carriers uni-directionally within the storage matrix and the at least one metal plate of each inner cell module is configured to stabilize the respective carrier when the carrier is moving or at a stationary position.
