ED-E

Eyebot (Duraframe) – Subject E, or ED-E for short, is a 6 year old shop security robot at Primm. His armor and weapons are more advanced than standard eyebots.

Background
ED-E comes from the East Coast, most likely from the Capital Wasteland. Unlike standard eyebots, ED-E is a highly customized "duraframe" model with hardened armor and specialized weapons. It was an eyebot on an incredible journey, carrying an enormous amount of valuable data when it was badly damaged and taken in by a Primm shop owner: the Nash Residence. Though ED-E still retains all of its data and an understanding of its mission, its internal positioning hardware is badly damaged. The only reason it has not been seized by interested parties is because ED-E has not communicated its special mission to anyone. ED-E is seen trying to fulfill its mission in the trailer video, where it is shot twice by an unseen shooter, and then it heads towards the New Vegas skyline in a heavily damaged but still functioning state.

Appearances
ED-E can be found in Primm lying on a counter in the Mojave Express building. When you first come upon him he will not be functioning due to the two bullets he took on his way to New Vegas. To fix him it requires a 65 repair skill, or 35 with 55 science skill, or he can be repaired with 3 scrap metals, 2 sensor modules and 1 electrical part. After he is repaired he can become your companion.

Behind the scenes

 * The name is a play on the 2005 film "Stealth" about an unmanned aerial vehicle gone rogue titled EDI (Extreme Deep Invader). In "Stealth", EDI's central processor is shaped as a ball, which resembles the eyebot, which is likely the reason the developers picked the reference. ED-E also plays music when a fight initiates much like the Extreme Deep Invader from "Stealth".
 * There is also an AI system in Mass Effect 2 called EDI.

Bugs
(XBox360) Completing the quest "Ed-E My Love" by giving him to the Followers may result in him teleporting to a location near red rock canyon(shown by quest marker) and then exploding on approach, removing him from the game as a companion.
