Robot

A robot is a machine capable of autonomously completing tasks. Depending upon the robot, these tasks may be simple or complex, and may require little human intervention or complete oversight.

In the Fallout universe, robots had been constructed for many purposes, and many examples survived long enough to be a factor in the Fallout world.

Robots had been constructed by pre-War society to fill all niches and occupations. From general-purpose utility droids to full-fledged military battle machines, robots could be found in almost any environment and function.

Programming
Typically, robots are equipped with a basic programming structure that dictates behavior and priorities. In most cases, these rules are effectively set in stone, and there's little the player can do to influence them. However, robots also develop personalities. Whether this is an intended feature present from manufacturing or the cumulative result of centuries of poorly-attended operation is unclear. Some robots, such as the Nuka-Cola shipping foreman appear to have rather harsh personalities present from their first days of activation, while others, such as the Protectron series seem to have little personality at all. At times, this personality gestalt seems to operate at odds with the fundamental core programming of the robot.

Notable examples of this discontent include Cerberus, the Mr. Gutsy robotic soldier that patrols Underworld. Despite programming to protect the ghouls of the city, Cerberus nevertheless admits quite freely that it detests the ghouls and, were it not for his combat inhibitor, would likely kill them all. Sawbones, resident medic at the Citadel, has an unhealthy interest in pain driven by his personality, while his programming clearly states he is a medic. Robots can even exhibit finicky personalities, one such Mr. Gutsy RL-3 will exhibit distaste in anyone without neutral karma.

Even robotic butlers show contrary streaks, although these aberrations are less likely to cause grievous bodily injury. The butler present in the player's home in Fallout 3 is often overheard saying with a cheery voice "How can I serve you master?" while muttering, sotto voce, "Not that I really want to" some seconds later.

Robots are often pressed into emergency duty outside their normal menu of skills, although this meets with varying degrees of success. A general-maintenance Mr. Handy will likely make a poor medic.

It may also be noted that without proper supervision, robots may handle situations rather extremely. Metro protectron will kill an unarmed person if they do not have a ticket, on top of this they do not accept red pass or blue pass cards, meaning someone traveling on these lines may be attacked even with proper authorization. Another note is that the Factory Protectron mentioned on the computer terminal in The Pitt killed all the workers when they refused to leave the mill and their jobs. Also, Milo the shipping foreman, a type II Mr. Handy robot, had trapped a group of employees in a locked closet to die, and for very minor infractions (taking a longer lunchbreak, for example). With this in mind it can be safe to say that robots of the fallout universe do not follow Asimov's three laws of robotics, or if they do very loosely. It would seem that east coast robots have a naturally adverse attitude towards humans, or animated things in general- living or robotic, as all the robots feature a combat "inhibitor" meaning that the robots all exhibit an uncontrollable urge to kill, without the inhibitor anyway.

Dealing with robots
While some robots in the Fallout wastelands are benign, most are following centuries-old programming -- or newer programming -- that classifies the player as a threat. To that end, effective anti-robot combat strategies are a must.

Most robots are highly resistant to damage from conventional weapons. Bullets do not generally affect robots as severely as they do their organic masters, and militarized robots can generally shrug off grenade shrapnel. However, like all electronics, robots are vulnerable to the effects of an EMP, making pulse weapons the ideal choice for disabling a robotic enemy.

Pulse grenades, pulse mines, and 12 Gauge EMP Shells are ideal for disabling a robot quickly, and though these munitions are typically expensive, they are much more efficient in a cost-for-effect frame of mind. Explosive weapons like missile launchers or miniature nuclear weapons are effective, but more costly to use against robots.

Players with sufficient Repair skills, or certain perks can disable inattentive robots, while players with sufficient Science skills can occasionally find control terminals that can shut down or reconfigure patrolling mechanical marauders.
