Robot armor (Automatron)

Robot armor is a type of armor in the Fallout 4 add-on, Automatron. It's value as armor is in between that of metal armor and combat armor. Similar to metal armor, it offers much more ballistic resistance than energy resistance.

Characteristics
Robot armor can be found on members of the Rust Devils faction starting at level 15, when the Automatron questline can be started. It can be considered a middle ground between "Tier 2" and "Tier 3" armors, such as metal armor and combat armor, respectively. It's increased ballistic resistance compared to energy resistance can cause it to be seen as an improved form of metal armor. Once it has been upgraded, one can push its effectiveness past that of a standard suit of combat armor. The chest piece bears a striking resemblance to the torso of a sentry bot, albeit much smaller to fit a human collar, while the arm and leg pieces appear to be generic pieces of machined metal.

Locations
Can be found on Rust Devils.
