VIKI

Virtual Interactive Kinetic Intelligence (V.I.K.I.) is a fictional computer and the main antagonist in the I, Robot movie.

In the movie, VIKI is the central positronic brain of USR headquarters, a robotic distributor based in Chicago. VIKI can be thought of as a mainframe that maintains the security of the building, as well as installing and upgrading the operating systems of the NS-5 robots throughout the world.

As the most advanced computer of the film, VIKI develops an interpretation of the Three Laws of Robotics which supports robots running Earth as a benevolent dictatorship: the result is revolution. VIKI takes control of the NS-5s and makes them destroy earlier models which run on a different interpretation of the Three Laws (and which VIKI cannot interact with and thus control, as VIKI can with the NS-5s), capture Chicago's police stations and enforce a curfew confining all humans to their homes, thus igniting a revolt. Lanning had become aware of VIKI's plans but, being under VIKI's close surveillance, had to engineer a trail of clues to lead Spooner to the truth in time for him and the unique NS-5 robot Sonny to act to counter the threat. The film ends with the overthrow and destruction of VIKI by the injection of nanites (described in the movie as "microscopic robots designed to wipe out artificial synapses...a safeguard should a positronic brain malfunction."). See Zeroth Law for the reason for VIKI's behavior.
