ED-E

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

Background
ED-E is an Enclave eyebot from the East Coast, built by Whitley at Adams Air Force Base. A prototype "duraframe" model, it contains an enormous amount of valuable data and was sent on an incredible journey, first going to Navarro for upgrades, then continuing its mission but being shot twice by an unidentified sniper before finally deactivating near Primm. It was found and taken in by the owner of the local Mojave Express branch, Johnson Nash, but it was never repaired before the Powder Gangers arrived in town. When the Courier arrives in Primm, ED-E remains unfixed, but if repaired, ED-E will join the Courier on his or her quest.

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.

Interactions with the player
To fix it requires one of:
 * 65 repair skill
 * 35 repair with 55 science
 * 3 scrap metals, 2 sensor modules and 1 scrap electronics

Endings

 * If ED-E remains forgotten in the shop of Johnson Nash, it is eventually repaired by another courier who let it continue on its journey to Navarro. ED-E is eventually discovered by the Followers of the Apocalypse who managed to recover vast databanks of scientific knowledge.
 * If its logs are never cleared, ED-E travels with the Courier until one of its memory banks is triggered, causing it to continue its travels on to Navarro. Upon reaching Navarro, ED-E vanishes and is not seen in the wastes again.
 * If its logs are cleared and its systems are upgraded by the Followers, ED-E remains a vigilant and constant companion to the Courier. The Followers of the Apocalypse use the information recovered from ED-E on Poseidon Energy to develop new methods to harness the energy of the sun.
 * If its logs are cleared and its systems are upgraded by the Brotherhood of Steel, ED-E remains a vigilant and constant companion to the Courier. The Brotherhood uses the information recovered from ED-E to create a small army of Duraframe Eyebots.
 * If the Courier never returns to Primm to recover the upgraded ED-E, the robot is discovered by a travelling caravan, who take it on as a protector as they wander the wastes.

Appearances
ED-E appears in Fallout: New Vegas.

Unexplained attacking or hostility against NPCs

 * Sandboxing AI sees food (including water) on ED-E or Rex and decides that the only way to get that delicious food is to kill them. Because they are not NPCs (in code, they are "creatures"), this is "legitimate" behavior. Obsidian Entertainment have fixed this behavior for the upcoming patch. Until then, a workaround is to remove food/water items from Rex/ED-E before sandboxing AI get near them.
 * Despite the apparent hostility caused by these situations, occurrences of this bug will not cause any lingering hostility between the Courier and any specific faction or group of NPCs.


 * ED-E may sometimes become inaccessible, or disappear, most notably in the quest where you interrogate the prisoner at Camp McCarran and ED-E gets locked in the Interrogation Room. This and any other disappearance, can be rectified by travelling to Vault 22 and using the elevator to travel to any floor, but the quest involving Keeley will need to be completed first. Verified on Xbox 11/30/10 after having lost ED-E for about 20 hours game play time. (This does not always work)
 * When you give ED-E to the Followers of the Apocalypse, or to the Brotherhood of Steel in the quest, ED-E My Love, the NPC ED-E actually disappears and is replaced with a near-identical one with upgraded systems, so be sure to remove anything in its possession. PC players can access the original ED-E's inventory directly with the console. Open the console, type, hit enter, type , hit enter. Take what you want out of old ED-E's inventory. (This is actually a very strange transportation glitch, ED-E's inventory will be transported into one of the locked footlockers at the entrance to The Old Mormon Fort, however stealing the key and unlocking the footlocker will cause all the Followers of the Apocalypse members to immediately attack you.)
 * ED-E has common clipping problems (falling through floors, getting stuck in objects or the ground, etc.).
 * ED-E often is not waiting where you expect it to be.
 * Completing the quest "ED-E My Love" may result in ED-E no longer moving or shooting anybody. It will still fast travel with you and zone with you, but will stay where you spawn. Changing it from follow to stay, and then back to follow fixes this problem, but it still won't attack enemies.
 * This can be fixed on the PC by simply opening the console(~), clicking on the ED-E so that it's name and ID will appear at the top of the screen, and entering the command . Beware, however, that this will reset ED-E's inventory, so you should apply the above procedure before doing it.
 * After upgrading ED-E, the "Enhanced Sensors" perk may no longer function properly.
 * If you fix ED-E before saving Primm from the Powder Gangers, Johnson Nash will not give you the quest ED-E My Love, even if you talk to him about ED-E. If you directly head to the Gibson Scrap Yard and talk to Old Lady Gibson the quest will automatically trigger.
 * ED-E delivers a message from the BoS after enough trigger words are activated. During the last paragraph of this speech, the speaker's dialect changes to that of a Hispanic male, and the player is stuck without being able to bring up the Pip-Boy or move. Quitting to dashboard and reloading does not fix this bug, however entering via console seems to fix the problem on PC.
 * If ED-E is rendered unconscious via an explosion it has a tendency to disappear, but will remain stuck as a companion. If ED-E disappears but is still a companion (check if you still have the Enhanced Sensors Perk) e.g. After triggering the Vault 22 explosion/fire, Use the console with the command, then you need to type, followed by , then .  It may also be necessary to use  as well in order to retrieve him as he may have been marked as dead despite being essential.
 * disable/enable/moveto player resulted (on PC) in ED-E returning hostile. A subsequent kill/resurrect reset ED-E's status to non-hostile, but needed ED-E to be dismissed and reacquired as companion before being able to fully interact with player. Immediate reacquisition with player.moveto immediately after dismissing ED-E, rather than reacquiring at Primm.
 * Choosing to upgrade ED-E's weapon may possibly cause ED-E to return with no weapons at all. Adding the upgraded zapper, by typing in the console with ED-E selected, will effectively fix this problem.verified on pc
 * ED-E's weapon may sometimes appear to be floating in midair underneath it. To fix this, fire ED-E and follow it until it goes through a door to a new area. Go through a couple of seconds after it and it should look normal again. Then you can re-hire it. Quickest way to do this is to just enter a house and fire it there right in front of the door. Experienced with armor-upgraded ED-E.
 * Like other companions, ED-E will drop faction armor like the Brotherhood T-51b power armor and others that can be obtained even early in the game. Exercise caution when loading ED-E's storage, as you might not notice the dropped armor and error message.
 * During the quest Ant Misbehavin', ED-E may become zoned out or stuck in one of the walls of the Nellis Generator room if you activate the sonic device giving to you by Loyal and may stay there. If this happens you will not be able to see or speak to ED-E but others can still see him and comment about ED-E's presence and you still receive ED-E's perk. To fix this just reload a save before activating Loyal's Sonic device and it should revert things back to normal. Even when not doing this quest, ED-E may "disappear" at Nellis Air Force Base.  The player will still have the Enhanced Sensors perk, but ED-E will not be present.
 * Because of a glitch where companions lose their default weapons upon exiting a casino, ED-E sometimes loses its only weapon and becomes useless in battle.
 * ED-E will also still fill space in your party, even when he is destroyed.
 * ED-E can explode if damage is done to him while he is unconscious. You will not be able to get your equipment back. Confirmed.
 * After upgrading ED-E and telling him to go to the Lucky 38, he may attack or be attacked by the Securitrons guarding the north gate to the strip. This can result in ED-E disappearing.
 * ED-E is not needed to receive the "Whole Gang" trophy.
 * If you tell ED-E to wait, and you go to certain locations, ED-E will randomly show up and rejoin your party (Happened on PC while in Vault 34 and on the "All or Nothing" quest.
 * Sometimes the tune that is played by ED-E when in battle may echo and you will hear the tune 3 times at once.
