Humanoid robot

C-27 Series humanoid robots are a type of robot utilized by the Calculator in 2197.

Background
Created by the Acme corporation before the Great War, C-27 Series humanoid robots are the main work force for the Calculator. As the name states, they are bi-pedal, two armed robots, about the size of a large man. Due to budget cutbacks by the Department of Defense (because of a false sense of safety as a result of the repeated drills) for Vault 0, several important backup systems were not included to the neuro-link systems.

This resulted in the corruption of the Calculator and instead of releasing the robots to make the Wasteland safe for humanity (it appears to be designed to adapt to human technology and weaponry), the robots manufactured from Vault 0 used its arsenal and anywhere else that sufficient armament could be found, to exterminate all life, completing the so called "pacification protocol". It can use most normal human equipment, with any sort of RS-231.5 interface required by most robotics.

Interactions with the player character
After the end of Fallout Tactics, the Warrior destroys the Calculator and disables all humanoid robots (estimated end of Fallout Tactics). The only possible survivor is HR 1205, a humanoid robot reprogrammed by the Brotherhood of Steel.
