Ada

Ada is a robotic companion living in the Commonwealth in 2287.

Background
Ada is a heavily modified assaultron robot, with sentry bot and protectron parts, and was created by Jackson. She traveled with his caravan, which specialized in mechanical repairs and trade, and travelled throughout the Commonwealth. Jackson's caravan attracted the attention of the Mechanist, and after three attacks, every member of the caravan except Ada had perished.

Quests

 * Mechanical Menace: Ada and her caravan are under attack from the Mechanist's robots, it's up to the Sole Survivor to try and save them.
 * A New Threat: Ada and the Sole Survivor travel to the General Atomics factory to engage the Mechanist's forces.
 * Headhunting: After finding the first Radio Beacon, Ada tasks the Sole Survivor in finding more - in hopes of them finding the Mechanist.
 * Restoring Order: Ada now knows the location of the Mechanist - it's time to stop them once and for all.

Appearances
Ada appears only in the Fallout 4 add-on Automatron.

Behind the scenes

 * Ada is likely named after Ada Lovelace, a real-world mathematician and an early innovator in the field of computer science. She shares her namesake with Lady Lovelace, another assaultron present at the Easy City Downs.
 * Some of Ada's dialogue lines are references to pop culture and science fiction. For example, "resistance is futile", is a reference to the Borg in Star Trek.

Bugs

 * As a companion, Ada will repeatedly back up and run into the player.
 * Ada, or any created bot, may turn hostile upon encountering robots in other locations, causing other NPCs in the same faction to also turn hostile. This has been known to apply to...
 * Old Rusty in Vault 81
 * The Mister Handys at Graygarden
 * KL-E-0 in Goodneighbor
 * ...although the exact conditions for this to occur are currently unknown.
 * Ada will quickly float around after the player's first encounter with her.
 * The "Regeneration Field" mod on the assaultron torso sometimes needs to be built twice using the materials twice and instead produces the "Resistance Field" in its place.
