Securitron

, or RobCo security model 2060-B is a robot model produced before the Great War by RobCo. After the Great War, they can be encountered mostly in and around New Vegas.

Characteristics
One of the deadliest robots to ever ride the face of the Earth, the Securitron is a monowheel robot with a titanium alloy frame, housing its electronic core and the television screen used to display a face indicating its purpose and alert status. In order to interact with the environment, it has two flexible arms with built in weapons and pincers.

On the subject of weapons, the Securitron is a wheeled powerhouse. Each comes with a set of four weapons: a 9mm submachinegun for close range suppression and crowd control, a Glastinghouse, Inc. X-25 Gatling laser against soft targets at medium range, M-235 rocket launcher for ground and air targets at long ranges and a rapid fire G-28 grenade launching system to enhance its lethality in close-range engagements. However, due to an inferior OS with outdated drivers, Mr House's Securitrons are unable to make use of their primary weapons, the rocket and grenade launchers, having to rely on the SMG and Gatling laser in combat. Securitrons are extremely tough unless you hit them in their weak spot - aim for their wheel, and you can destroy them in one or two shots.

Securitrons seem to have some sort of connection between themselves and the ability to transfer personalities, as can be observed in the Yes Man and Victor.

Securitrons are the hands and eyes of Mr House and roam the Strip enforcing his law.

Interactions with the player character
The player can choose to upgrade the OS of the Securitrons on behalf of Mr House. With the Mark II operating system hidden on the Platinum chip, the securitrons gain access to their primary weapons and become an enemy not to be taken lightly. The Securitron's face also changes from a humble policeman to a hardened soldier.

Appearances
Securitrons appear in Fallout: New Vegas, Mainly on The Strip
