ED-E

 (known as ED-E), 6, is a shop security robot at Primm. His armor and weapons are more advanced than standard eyebots.

Characteristics
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. 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
ED-E can become your companion. While he is your companion you will get the perk Enhanced Sensors. With this perk you can detect enemies at a very far range, and enemies that are cloaked can also be targeted in V.A.T.S.

Appearances
ED-E appears in Fallout: New Vegas.
