Rabert is a rare Scots form of the name Robert, and Petrosian is an Armenian surname. These are two very disparate cultures. It's more like that it was a Chinese transliteration of the name Robert Petrosian, an actual Armenian person.
It just looks like a Chinese ghost writer for a non-existent person, with a poor grasp of how English actually works.
