Abstract

A robotic storage and retrieval system is provided. The robotic storage and retrieval system may include a three-dimensional storage rack, a set of article holders, and a robot. In one embodiment, the storage rack has a plurality of rows, a plurality of columns, and one or more support members at each unique row and column position. Each set of article holders is located at one of the unique row and column positions, and each article holder within a set is vertically supported by the one or more support members. The robot is configured to store the article holders to the storage rack and to retrieve the article holders from the storage rack.
