# Storage and retrieval system

## Abstract

A storage and retrieval system comprising: a grid framework structure including a plurality of storage columns for storing stacks of storage containers, and a track system arranged in a grid pattern above the storage columns for guiding one or more robotic load handling devices, each storage column being below a single grid cell; a plurality of stacks of storage containers, each container having a bottom wall and upwardly standing sidewalls and end walls, each stack occupying a single storage column, the stacks including a plurality of first type storage containers having a metallic container body and a plurality of second type storage containers having a wireless transmittable container body; and an environmental monitoring system including at least one environmental sensor with a wireless communication device stored in a second type container to define a sensor container, and a base unit external of the grid framework for receiving environmental data.
