Protectron

Protectrons are a model of robot which appear in Fallout 3 and Fallout: New Vegas.

Background
 Created by the RobCo corporation, protectron robots were designed (as their name suggests) for protection, although they can also be seen being used in a manual labor role as well. Typically used in office-type settings, their secondary programming is modular, making them useful as greeters, ticket collectors, sexual partners, bartenders, or celebrity or historical figure impersonators. In terms of combat, protectrons are somewhat extremely weak and easy to defeat. 

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.

Metro protectron


Metro protectrons are a model of protectron found in Washington, D.C.'s metro stations that will ask for the player's metro ticket when activated, and the player's metro ticket will be removed from their inventory. If they do not happen to have a ticket in their inventory, the protectron will attack.

Factory protectron


Factory protectrons are protectrons designed for use as manual labor inside of factories. Computer entries inside Sunset Sarsaparilla Headquarters in Fallout: New Vegas mention robots being shipped to the factory to replace the human workers. This is probably the case in Fallout 3 as well, and a few examples of these protectrons can be found inside The Mill in the Fallout 3 expansion The Pitt, although they are already deactivated.

Shipping worker


Shipping workers are protectons found in the Sunset Sarsaparilla Headquarters. There are only two of them, and they can be found on the bottom floor 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 within the factory and scavenged 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.

Behind the scenes
The protectron's design seems to be inspired by Robby the Robot, a robot that appeared in the 1950s Sci-Fi film The Forbidden Planet.
