Microprocessors 10 mounted on wall accessors 14 not only monitor and control, the X, Y and Z positions of the wall accessors 14 they ride on, but also identify, count, store and/or fetch the items of inventory in the cubby holes 16 of the parts' wall 12. Both wall accessors 14 share a common track together with a common absolute position encoder strip along the track. The inventory control computer, controlling the two accessors as its left and right arms, maintains the record of the inventory in its nonvolatile data bases to protect it against possible power outages. Each accessor 14 is serviced with power and commands over a flat umbilical cord 20 that is mounted on rollers kept under a steady tension by a constant K spring.
