The following is based on and has not been confirmed by Van Buren canon sources.
robobrain is a type of robot used in the American southwest in 2253.
Robobrains were created before the
Great War by General Atomics International both for the U.S. military and for the civilian sector. Official government records list only chimpanzee brains as being used in the robots, but at least some human brains were taken from the bodies of executed criminals.  Many of these criminals were insane, so the resulting robobrains also tended to be unstable, despite complete reprogramming  via the  CODE technology. Some of these human-robobrains hybrids would try to kill themselves, apparently resenting being made into cyborgs.
Robobrains were to appear in
, the canceled Van Buren Fallout 3 by Black Isle Studios.
