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: After it is fixed it can become your companion.
 * 65 repair skill
 * 35 repair with 55 science (65 science on the Xbox 360)
 * 3 scrap metals, 2 sensor modules and 1 scrap electronics *See notes

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

Unexplained aggro

 * From J.E. Sawyer:
 * BTW, RE: Rex/ED-E being randomly attacked:


 * We discovered what was causing this. 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. We have fixed this behavior for the upcoming patch. Until then, a workaround is to remove food/water items from Rex/ED-E before hungry, hungry sandboxing folks get near those dudes.

This behavior doesn't cause a population to become hostile to you, even though they may continually assault your companion. You can safely ignore the fray, as ED-E will revive a short time after being knocked unconscious and will remain with you if you fast-travel away from the area. Downsides are that ED-E can potentially kill an NPC that is integral to a quest or activity.

Other bugs

 * 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. ED-E will reappear!!
 * 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 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" 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.
 * 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.
 * 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.
 * 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 lose their default weapons upon exiting a casino, ED-E loses his only weapon and becomes useless in battle.
 * Sometimes ED-E just disappears permanently, after you sent him back to Lucky 38 or Primm. If you can't find him anymore, try to bring him back with
 * Using the command to make ED-E appear and talking to anyone  that triggers ED-E's logs in the quest ED-E My Love (needs to be verified, only tryed with Ignacio Rivas), may result in another ED-E appearing besides the one that is already following the player.
 * ED-E may randomly become hostile to the player and any NPCs in the area when you return to the Nash Residence after an incident when he disappears and the player gets a message saying he has returned to Primm.
 * ED-E can disappear, but still be listed as your companion (you still will have enhanced sensors perk). NPCs will still make comments about ED-E, but he's not there. This is very problematic in instances like visiting Ceasar, as you must tell your companions to wait, but you can't because he's not there, so the main story quest will become incompletable. This is confirmed on both 360 and PS3, and effectively breaks the game. Nonetheless if this happens and you have another companion with you (confirmed with Raul and a game without title update) making the other companion wait is sufficient enough to get into Ceasar's tent. Or, if Ed-E is your only companion, prior to entering Lucky 38 for the first time, you can make him wait, and then immediately head to Ceasar's tent. Fix: If you kill the praetorian guard outside of Caesar's tent without alerting other legionaries, you can enter caesar's tent without a problem.
 * You may lose all items in ED-E's inventory when go to The Fort and give weapons to the Guard, he may become passive after going to the Weather Bunker too
 * ED-E can explode if damage is done to him while he is unconscious. You will not be able to get your equipment back.
 * 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.
 * If you are entering Vault 34, probably best to tell ED-E to wait outside. I took both ED-E and Boone in with me, only to lose ED-E somewhere in the Vault (I assume he got "stuck" somewhere). I had left the vault before I realised this, but on my return I could not find ED-E anywhere. This caused problems later as I could not accept Rex as a companion as the game still assumed that I had ED-E with me - I even had random NPCs making comments about him, even though he was nowhere to be seen!
 * Ed-E is not needed to receive the "Whole Gang" trophy.
 * While in Vault 22, make sure ED-E is in the blast room with you before you ignite the gas to clear the Vault of thespores. If he is subject to the blast, the game will say that ED-E is unconscious, but ED-E will explode. However, if you travel around, people will still acknowledge his presence. For instance, Boomer Gaurds will still say things such as "I can take care of that robot problem for you. Just saying," even though ED-E is dead.
 * Sometimes after the Follower's upgrade, if you put inventory in ED-E, if you enter and exit a building, and check ED-D, your ENTIRE inventory will be gone. (Needs to be Verified, it happened on my Xbox 360, entering and exiting Gomorrah)
 * 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; would recommend verification from another user.)
