US Patent 9242799 Dynamically reconfigurable inventory pods

An inventory system has inventory pods that are freely and independently moved about a facility and include inventory holders having dynamically reconfigurable storage bins. For various operating scenarios, the components of the inventory system are directed to dynamically reconfigure the storage bins, thereby maintaining efficient product density amongst the inventory holders and permitting the use of automated equipment to manipulate inventory items stored in the inventory pods. One or more inventory pods may be used with lifting modules and picking modules to dynamically reconfigure the storage bins as inventory items are added to and removed from the inventory holders.
