ED-E

"Eyebot Duraframe Subject E is both the prototype and the last functional model."

- Whitley

Eyebot (Duraframe) – Subject E (or ED-E for short), is a prototype eyebot and possible companion in Fallout New Vegas in the year 2281. Its armor and weapons are more advanced than a regular eyebot's.

Background
ED-E is an Enclave eyebot from the East Coast and is built by Whitley at Adams Air Force Base. A prototype "duraframe" model, it has been enhanced for regular combat as opposed to the original model, which functions primarily as a mobile radio transmitter. However, the war with the Brotherhood of Steel necessitated increased production of Hellfire armor, and so ED-E was the only surviving model. Whitley uploaded an enormous amount of valuable data on Poseidon Energy and his duraframe research into ED-E's logs, then dispatched it on a cross-country journey to Navarro, past Rockville, Hagerstown, the Pitt, Dog Town, Nephi, Zion Valley, Caliente, the Hub, Necropolis, Lost Hills, and San Francisco.

ED-E's first stop was an unspecified Enclave outpost in Chicago for upgrades and repairs. ED-E then traveled across the Mojave Wasteland where it was shot twice by an unidentified sniper, dealing a large amount of damage. This eventually forced it to deactivate near Primm, where it was found and taken in by a courier of the local Mojave Express branch and given to Johnson Nash. Unable to repair it himself, Nash left ED-E to languish on Primm's branch office counter, where it remained as the escaped convicts took over the town. When the Courier arrives in Primm, he/she is able to repair ED-E, allowing the eyebot to join the Courier on their quest as a companion.

Though ED-E still retains all of its data and understanding of its mission, its internal positioning hardware is badly damaged. The only reason it had not been seized by interested parties is because ED-E has not communicated its special mission to anyone.

Quests
ED-E My Love: Once ED-E's logs are discovered, the Brotherhood of Steel and the Followers of the Apocalypse will both express interest in it, offering upgrades in exchange for its data.

Other interactions
When first found in the Nash Residence of Primm, ED-E is broken and lying on a table. To fix it requires one of the following:
 * Repair skill of 65
 * Repair skill of 35 with a Science skill of 55
 * 3 pieces of scrap metal, 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 lets it continue on its journey to Navarro. ED-E is eventually discovered by the Followers of the Apocalypse, who manage 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 traveling caravan, who take it on as a protector as they wander the wastes.

Notable quotes


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

Bugs

 * ED-E can be used to carry an unlimited weight of supplies by filling his inventory to 210 pounds then adding a MF Breeder to his inventory (other weightless items might work as well). This unlocks the seeting that indicates his inventory is full and you can continue to add weight to his inventory. It will still read 210, but when you empty his inventory you will be able to unload far more than the 210 pounds indicated.
 * If you tell ED-E to part ways and return to Primm, he may be removed from the game instead.
 * Exiting Bloodborne Cave may glitch ED-E to be stuck in the opening of the cave. Even with the latest patch, ED-E will instead show up as a marker, but can't be found in the surroundings or in the cave. This can also happen around the entrance of Vault 22.
 * ED-E will get stuck in all the towers in Hoover Dam, mixing up what door to take to follow you. He usually ends up on the roof of the tower you exited. If you take the Elevator to Hoover Dam Offices he will usually appear (After second patch).
 * ED-E is often rendered unconscious via explosions, and may make it disappear. This may also happen when ED-E sustains enough damage while already unconscious (tested using Knock-Knock and Holorifle on a knocked-out ED-E). As a result, ED-E will vanish from the game, but the player will still keep its companion slot and the Enhanced Sensors Perk . This means that you won't be able to recruit Rex as a result of his slot being taken up. You also won't be able to take Arcade Gannon with you if you encounter his bug where you won't receive a dialogue option to travel with you while ED-E is already a companion. More importantly, this bug will make it impossible to play the Honest Hearts DLC, as you cannot take companions with you into Zion. The same applies to the Boomer artillery bug below.
 * Boomers artillery will kill ED-E, even on normal mode. You will not be informed of its death.
 * When at Black Mountain, it is possible that ED-E will disappear after the Courier is attacked by super mutants in the small pass with the bear traps and the large boulder. [Confirmed]It can also happen in the entrance of Vault 22. This might be fixed by going to Sierra Madre (and starting the Dead Money DLC). There will be a message saying that ED-E has returned to Primm.
 * After upgrading ED-E's armor, its inventory weight goes up from 1 to 2. Traveling to the Fort and back with ED-E as a companion permanently adds an additional 2 to its weight EACH time you go there, eventually making it impossible to place items in its inventory anymore. There is no known way to remove this invisible item weight, and the only way to prevent it is by firing ED-E before traveling there. Telling him to wait elsewhere before going to the Fort still adds the extra phantom weight. Apparently, its laser is being duplicated each time your weapons are forcibly removed at the Fort. This does not happen at the casinos, though.
 * After upgrading ED-E with the Followers, if it is destroyed, the dialogue and text about losing its perk after its death will not appear at all. You can lose ED-E without noticing its death in battles or if it strays too far from the Courier by its own way being in [DANGER] mode because of the hostiles around it. A related bug exists where if ED-E is destroyed, its perk still remains in the Courier's Pip-Boy and still fully working.
 * ED-E delivers a message from the Brotherhood after enough trigger words are activated. During the last paragraph of this speech, the speaker's dialect changes to that of a Hispanic male (possibly from one of the developers of New Vegas), and the player is stuck without being able to bring up the Pip-Boy or move. The following speech made by the Followers of the Apocalypse will not play. Quitting to dashboard and reloading does not fix this bug. However, entering via console seems to fix the problem on PC. You may also try telling ED-E to wait in a place prior to receiving the message and retrieving him later.
 * The Upgraded Zapper from the Followers of the Apocalypse upgrade can be lost at random, particularly in casinos or in Caesar's Fort. It is actually two different weapons: Energy Zap(00166B94) and Electrical Zap(001694DF), and can be restored with  after targeting ED-E. They require energy cell ammo (00078CC2), but don't actually consume it.
 * When at The Thorn (Near Westside), if you have ED-E wait by the edge of the platform where Red Lucy is standing, it will attack the creatures you may be fighting if you are inside the arena.
 * It is possible for ED-E (after the armor upgrade) to not use its weapons and not even move. If you fast-travel or use the wait command, it will rejoin you.
 * Sometimes while speaking to ED-E, a gunfire sound will trigger instead of the regular beeping noise.
 * It is common for ED-E to get stuck under the walkways in the Hidden Valley bunker. It can also get stuck underneath the beds or the stairs.
 * ED-E will follow the Courier, but will not fire upon any enemies.
