Claim 7:
8. An autonomous transport vehicle comprising:
a transfer arm including at least one finger and a movable finger support member, the at least one finger being movably coupled to the movable finger support member so that the movable finger support member moves in a first direction relative to a reference frame of the autonomous transport vehicle and the at least one finger moves linearly relative to the movable finger support member in a second direction substantially perpendicular to the first direction in the reference frame of the autonomous transport vehicle, the at least one finger having set different incremental indexed positions of the at least one finger in the second direction between ends of a range of motion in the second direction; and
a controller configured to selectably vary a size of the transfer arm conforming to pickface size of a pickface transferred to and from rack storage locations of at least one storage rack of a storage space by differentially setting an incremental indexed position of the at least one finger between the set incremental indexed positions between ends of the range of motion in the second direction relative to the incremental indexed position set for another of the at least one finger movably coupled to the movable finger support member,
wherein the autonomous transport vehicle and the at least one storage rack, with the rack storage locations, of the storage space are disposed so as to define random access storage to each rack storage location of the at least one storage rack.
