What profession, faction, special workbench, etc.?
Being able to scavenge partial/broken bots and then fix them up, set yourself as Qwner would be OK.
Maybe.
In FO2, the prospector who sells you the map to Vault 13 tells you the story of his discovery. In the story he had a Mr.Handee as a guard/companion.
So having a robot sidekick is Fallouty.
