Although they were considered one of the most advanced cyborgs ever created, Robobrains never reached full production status. Persistent problems with aggression and violence even in properly CODE-conditioned robobrains, Until its closure, SAD experimented with developing a new kind of cybernetic brain explicitly designed for use in Robobrains, while RB-2851 focused on manufacturing and iterating on existing solutions. Although the first brains were procured from primates (typically chimpanzees), persistent equipment failure in brain extractors that were incapable of working at an industrial capacity, and flaws in the immature technology used to manufacture Robobrain chassis resulted in a limited trial run. RB-2851 alone managed to complete three batches, with a further two planned. Each batch provided superior upgrades to the robot, including increased energy efficiency, maintaining brain longevity, improved visual cortex connections to enhance motor skills and perception, and tactical combat capabilities.
Developed by General Atomics International with the assistance of RobCo Industries, the robobrain was designed from the ground up as a multirole platform for use by military and civilian clients. They are more flexible and powerful than robots due to the fact that their central control and processing unit is an actual brain, rather than an artificial facsimile. Coupled with a robust, all-terrain tracked chassis and powerful armaments, the robobrain was on the forefront of a new revolution in combat robotics.
Robobrains are a fairly common sight in the Capital Wasteland. They can be found in many abandoned buildings, in use by groups such as the Enclave and the Brotherhood Outcasts, or even simply wandering the wastes.
There are three variants of the robobrain. The first, and most common, is the military variant used by the U.S. Army, recognizable by its green paint scheme with a prominent white serial number stenciled on the front. They are more commonly used by various factions. Less common is the gray-colored civilian model, seen wandering the wasteland at random. The Point Lookoutadd-on introduces the final variant, the robobrain sentry, which is identical in the appearance to the civilian model but possessing significantly more health.
Robobrains are substantially more durable, accurate, and dangerous than the more commonly encountered protectron. Armed with a pair of integrated lasers each roughly equal in power to a laser pistol, the robobrain is a moderate threat, though easy to damage due to its size and extreme vulnerability to headshots. Every robobrain has a combat inhibitor on its back, and if the inhibitor is crippled, the robobrain will frenzy and attack indiscriminately.
Robobrains also possess a built-in Mesmetron. This attack does not cause much damage, but it may instantly cripple the head of the player character (dealing 1000 damage to the body part) and inflict the concussion status effect, resulting in blurred vision, hindered accuracy, and -4 base Perception. This is used to discourage melee and close-ranged attacks, where the robobrain is weakest.
↑The Sole Survivor: "Have you seen a robot with a brain like that before?" Ada: "No, but my old caravan discovered records about them while we were scavenging military facilities. According to my data banks, it's called the "Robobrain." It was considered one of the most technologically superior robots ever constructed, but the model never reached full production status." (Ada's dialogue)
↑The Sole Survivor: "Here you go, Ada. The final Radar Beacon. I'll need that head back when you're done." Ada: "Of course. Shouldn't take but a moment.There you go... still in one piece.I'm not sure why you want the head back. All we needed was its Radar Beacon.Besides, Robobrains are notorious for being... well, a real pain in the neck." The Sole Survivor: "What else do you know about them, Ada?" Ada: "Quite simply, it's the first time General Atomics produced a successful union between organic matter and robotics. The brain is used both as a control unit and a data storage unit which is far more efficient than using standard circuits.Unfortunately, there were a lot of programming issues with these robots which caused them to be a bit... shall we say, unhinged?Hopefully, this particular Robobrain will have some of the answers that we've been seeking." (Ada's dialogue)
↑Fallout 2 Official Strategies & Secrets p.33: "The Robobrain is a jack-of-all-trades robot. They have hands and are usually armed with assault rifles. The chimpanzee, or other primate, brain that was implemented into them makes them excellent guard robots. It's rumored that some were set up to accept human brains, but this has never been proven."
