Securitron

PDQ-88b Securitron, also named RobCo security model 2060-B, is a private security robot created and mainly produced by House Industries with the help of RobCo Industries, and privately by the Big MT company. Its form is vaguely humanoid, with two flexible arms and claw-like pincers for hands. Despite that, their hand are not suited to use tools and weapons usable by humans. On the front side is a screen displaying an image of a face, indicating the unit's purpose and alert status.

Characteristics
The PDQ-88b Securitron is a fairly large, monowheel robot with a titanium alloy housing, resistant to shrapnel and small arms fire. When killed, the screen will freeze in whatever position it was in when it was destroyed. The PDQ-88b Securitron is a heavily-armed platform. Its left arm contains its primary weapon, an X-25 Gatling laser for medium range engagements. For close-range suppression and crowd control, the Securitron mounts an 9mm cannon in its right arm. Also, concealed compartments on its shoulders contain M-235 missile launchers for long range and surface-to-air engagements, and a rapid-fire G-28 grenade launching system for close range engagements. The robots also have onboard auto-repair systems to repair any damage sustained from combat. Thus armed, a Securitron can handle nearly any combat situation.

The PDQ-88b Securitron of House Industries supports only two operating systems: Mk I and Mk II, opposite of Big MT model that supports six operating systems: Mk I, Mk II, Mk III, Mk IV, Mk V and Mk VI.

The Mk I operating system lacks drivers for the auto-repair systems and shoulder-mounted weapons, limiting the robots' arsenal to the built-in X-25 Gatling laser and the 9mm cannon. The Mk II operating system enables the M-235 missile launchers, the rapid-fire G-28 grenade launching system and the auto-repair system, increases the strength of its armor. Other superior operating system (Mk III, Mk IV, Mk V and Mk VI) made by Big MT increase gradually the power of weapon and defensive systems already present with better accuracy, resistance, firepower, auto-repair systems and allowing more missile to be launch with the M-235 missile launchers. Estimated by Mr. House and Yes Man, just the effectiveness per unit in combat between Mk I and Mk II is improved by 235%.

House model
They are the model created by House Industries with the help of RobCo Industries, the original creator of the PDQ-88b Securitron. After the Great War, they are almost all controlled by Mr. House and can be upgraded via the platinum chip.

Mark I
The Securitron Mk I can only use the X-25 Gatling laser and the 9mm cannon, and it can't used the auto-repair systems. The unit's face is that of a policeman.

* Possibly due to developer oversight, the Securitron Mk I's on the Strip have a DT of 0. The Securitrons in Freeside and inside the Lucky 38 have the normal DT of 20.

Mark II
Through the use of the platinum chip, the Courier may upgrade the Securitrons of Mr. House at The Fort and around The Strip to the Mark II operating system. The Securitron Mk II can use all the weapon available as the X-25 Gatling laser, the 9mm cannon, the M-235 missile launchers, the rapid-fire G-28 grenade launching system and can also use the auto-repair systems. Its armor is increased and the unit's face is that of an American Army infantryman.

Big MT model
They are the illegal model created in Big MT by Dr. 0 (already named like that at this time) and his team, with the purpose to surpasse the original PDQ-88b Securitron of House Industries and Robert House, for whom he had a deep hatred. In the process, they surpassed them and even make up a Mk VI operating system. However, after the Great War, all of Big MT Securitrons are either irreperably damaged or have gone berserk due to lack of maintenance for over 200 years.

Berserk
The unit's face of the berserk PDQ-88b Securitron is a distorted face.

Damaged
The unit's face of the damaged PDQ-88b Securitron is a crossed skull head.

Other interactions
PDQ-88b Securitron in the Mojave Wasteland are the hands and eyes of Mr. House. Notably, they patrol the Strip and guard its north entrance. Like all robots, Securitrons cannot be pick-pocketed, and attempting to do so will just trigger the Securitron to say one of their quotes.. The player may upgrade the units to the Mark II operating system through the use of the platinum chip.

Those of Big MT, however, are all hostile to the player, due the overheated by years of service.

Behind the scenes

 * If the courier has taken the Wild Wasteland trait, Securitrons may say "Your move, creep!" This is a reference to RoboCop, who uses the same line. Likewise, if the player chooses to frame Heck Gunderson for his son's murder during the "Beyond the Beef" Quest, the Securitron will say "Dead or alive, you're coming with me" before shooting him dead.
 * When in combat, Securitrons will occasionally say "Exterminate!" This is a reference to the Daleks from Doctor Who.

Bugs

 * While inside The Strip if you kill a Securitron with a head shot, destroying the TV monitor, the screen will still be present but the surrounding edges around the screen shows that the screen was destroyed.
 * One of the Securitron Gatekeepers (top right) will be missing from his post when fast traveling or just heading regularly to the Strip Gate. He can be found in an alleyway to the East of the gate, seemingly stuck between a light post, a dumpster, and the wall of the building to the North. Pushing it from this spot will cause him to roll back to his post. What causes this is unknown but it may be that the robot spawns in the position.
 * The Securitrons may sometimes keep swapping weapons without even attacking the enemy.
 * The Securitrons' (Mk I and II) pathfinding skills and ability to engage the enemy is so that they often get stuck in their location or refuse to move and shoot at hostile targets.
 * Sometimes companions will attempt to talk with a Securitron, except that Securitrons have no greeting dialogue. For example, it will reply: "Please, do not stand in the fountains." when greeted hello (or similar). Occasionally your companion will stay there indefinitely until you talk to the Securitron AND your companion.
 * When passing the science check with the Securitron Gatekeeper, and you talk with it again saying goodbye, the Securitrons might turn hostile while attempting to enter the Strip.
