Claim 6:
7. An order fulfillment system, comprising:
a storage structure, comprising:
vertical members supporting a grid including a first set of parallel rails extending in a first direction and a second set of parallel rails extending in a second direction substantially perpendicular to the first direction such that the first and second set of parallel rails collectively define grid spaces; and
a plurality of containers arranged in vertical stacks, each one of the vertical stacks configured to be arranged underneath a respective one of the grid spaces; and

a robot, comprising:
a body coupled to a wheel assembly, the wheel assembly including a plurality of wheels and an actuator to move the body along the grid;
a sensor to locate a position of the body relative to the grid on which the body is located;
an interface configured to send processor readable data to a remote processor and receive processor executable instructions from the remote processor; and
a container retrieval device including a hoist provided with a securement device, the hoist having a top surface, a bottom surface, three lateral sides, an open lateral side, and an aperture extending through the top surface and the bottom surface such that the hoist is extendable in a vertical direction at least partially around one of the vertical stacks to lift a plurality of containers from the one of the vertical stacks to a location above the grid in a single lift.
