The OR series were robot models developed by Numbani.
The OR14 "Idina" was a type of security omnic designed and built in the Nigerian omnium. After they were used in the Omnic Crisis, they were taken out of production and eventually replaced by the OR15. Unlike later models, the OR14's guns utilized regular bullets. Instead of a protective barrier, some models possessed an energy blade, while others wielded a second gun.
Based on the reaction of Baldericht, it's likely that the Battle of Eichenwalde was the first battle in the omnic in which the omnic forces utilized OR14 units, or possibly OR units altogether. Based on this, it's possible that they were specifically designed to compensate for the Bastion units weakness to Crusaders.

The OR15 Defense Bots were used as a defense force for Numbani. Twenty years after the Omnic Crisis ended, Numbani revived and recommissioned the OR14 program to create the OR15. As a successor of the OR14 model, OR15 protected the city of Numbani until several of them were destroyed in an attack from Doomfist. It lead to the decommission of the OR15 program, and the rest of the OR15 was sold.
