Protectron

Protectrons are robots which appear in Fallout 3 and Fallout: New Vegas.

Background
 As their name suggests, the protectron series of robot was devised primarily for protection and security operations, mostly in office-type settings, though their secondary programming is very modular and can be modified to make the Protectron perform many functions, such as acting as greeters, ticket collectors, sexual partners, bartenders, or even functioning as celebrity or historical figure impersonators. They were created by the RobCo corporation.

Protectron


In Fallout 3, as well as in Fallout: New Vegas, Protectrons are the second weakest robot variant encountered, with only the robobrain having less firepower. They do not pose much of a threat, due to their weaker weaponry and slow speeds. They are equipped with a hand-laser as well as a head-laser, so that in the event that one weapon is disabled, the Protectron can still function in battle. They are not as common in "Fallout: New Vegas" as they are in Fallout 3: they are in every metro station in the latter, whereas in Fallout: New Vegas, they are mostly found patrolling a few (office) buildings and the Securitron vault.

Shipping worker


Shipping workers are robots found in the Sunset Sarsaparilla Headquarters. There are only two of them. They can be found on the bottom floor in the large room of the factory with the bottle cap press machine.

Sunset Sarsaparilla security


Sunset Sarsaparilla security are a slightly tougher variant of the protectron, of which three are still functioning, and can be found patrolling inside the Sunset Sarsaparilla Headquarters. Their function was to protect the factory, possibly against industrial espionage. Several disabled models can also be found and scrapped for parts.

Protectron Mark series
The Protectron Mark series was an attempt by scientists in Big MT to improve on the base model of protectron built by RobCo. These protectrons come in six versions, Marks I-VI. Mark I is on par with the protectrons found in the Sunset Sarsaparilla Headquarters, while the other marks are scaled on increasing durability based on the players level. However, the firepower on each mark series is the same.
