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 comes from the East Coast. It was built by Whitley, an Enclave scientist at Adams Air Force Base. ED-E is a highly customized "duraframe" model with hardened armor and specialized weapons. It was an eyebot on an incredible journey, first going to Navarro for upgrades, then carrying an enormous amount of valuable data when it was badly damaged and taken in by a Primm shop owner, Johnson Nash.

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 toward the New Vegas skyline in a heavily damaged but still functioning state.

To fix it requires one of:
 * 65 repair skill (55 on the Xbox 360)
 * 35 repair with 55 science (65 on the Xbox 360)
 * 3 scrap metals, 2 sensor modules and 1 scrap electronics - all of these parts can be found in Novac on the shelves outside the gas-station across from the motel.

After it is fixed it can become your companion.

Appearances
ED-E appears in Fallout: New Vegas, and on the cover of All Roads, floating above the New Vegas crowd.

Bugs

 * If you set ED-E on "aggressive" mode it occasionally may start battles with other neutral NPCs (such as in Mojave Outpost (also confirmed in 188 Trading Post, Vault 22, and Camp McCarran).
 * Even if ED-E is set to passive, it has been observed attacking random NPC's unprovoked, often resulting in mission failure. This has been seen in Primm in the Vikki and Vance Casino.
 * When you give ED-E to the Followers of the Apocalypse, or to the Brotherhood of Steel in the quest, ED-E My Love, it will erase everything in its inventory. So be sure to remove anything in its possession. When ED-E is returned, it is essentially a different robot, you 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 Legion members to immediately attack you.)
 * ED-E has common clipping problems (falling through floors, getting stuck in objects or the ground, etc.).
 * ED-E might become hostile or cause other NPCs to become hostile seemingly without cause. Happened when ED-E was with me in Hoover Dam, especially near the Quartermaster. (The NPCs have not become hostile to anyone but ED-E)
 * A simple fix is to save, kill ED-E, (if ED-E is carrying items for you, loot them now or you will lose them), then use the console to resurrect ED-E. If you have not completed ED-E's quest, you will need to reset that as well. [This wont solve the problem causing ED-E as companion in Camp McCarran (see the bug section there). After a while the Recon members will attack ED-E again.]
 * Alternatively, you can have ED-E wait around the corner from key figures which trigger this glitch and then pick him up when you're done dealing the NPCs.
 * ED-E often is not waiting where you expect it to be.
 * Completing the quest "ED-E My Love" by giving it to the Brotherhood of Steel 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. Also reported to happen if you side with the Followers of the Apocalypse at the end.
 * 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.
 * When completing the quest ED-E My Love, you're given a chance to upgrade the robot either by giving him to the Brotherhood of Steel, or the Followers of the Apocalypse. To achieve this upgrade, the entity is swapped out with an entirely different base ID, without making the inventory persistent.  The effect of which is "destroying" any items in ED-E's inventory.  The items are actually not destroyed, but still stored in the old, non-upgraded ED-E's inventory.
 * To fix this issue on the PC, you can access the standard ED-E's inventory remotely using the console, then take your items from 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 Johnson Nash 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.
 * ED-E sometimes will kill Keith in Aerotech Office Park, unprovoked. This results in the failure of the unmarked quest given to you by Captain Parker where you had to prove Keith was cheating at caravan. After Keith's death, you can still gather the evidence needed to complete the quest, and notify Parker, and will be given a small reward (approx 100 caps). However, even if you agree to back up Parker when he decides to take Keith into custody, no action will be taken by Parker, and you cannot talk to him about Keith anymore.
 * If you attempt to place any faction armor into ED-E it will state that he cannot wear that armor and it will be placed on the ground. If you are in an owned building at the time, such as a house then that armor will become their property. It will be classified as stealing to pick it back up.
 * 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.
 * 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.
 * ED-E might randomly die on you, and then spawn when you enter a certain building dead, complete with a search option, but its corpse will "follow" you if you leave that building. This appears to have happened when swimming in the lake next to Camp Golf, however that is not a certain answer. I still have his perk and everything, he's just dead... had same problem, fixed by selecting it, for the one with weapon upgrade, and typing  and . Fire-and-recruit him to have the wheel menu back.
 * When opening ED-E's Inventory, do not give ED-E your power armor. ED-E will wear it and you won't get it back.
 * If ED-E disappears while it is one of your followers (and the vault 22 elevator trick doesn't work) then the main story quests will become un-completable as ED-E needs to be manually set to wait for the game to progress before entering Caesars tent.
 * 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.
 * If you receive the quest from Col. Cassandra Moore to destroy the Brotherhood of Steel bunker with ED-E in your party (NCR affiliation) ED-E will engage the Col and any NCR soldiers nearby, both sides will appear neutral to the player.
 * DO NOT RISK GOING IN WITH ED-E INTO A CASINO! Because of a glitch where companions loose their default weapons upon exiting a casino, ED-E looses his only weapon and becomes useless in battle.
