Robot workbench

The robot workbench is a world object in the Fallout 4 add-on Automatron. It is used to modify robot companions by equipping them with various robot mods, including Codsworth and Ada.

Crafting
The robot workbench, unlike other workbenches, appears in the "Special" category of the workshop menu, and doesn't require Local Leader rank two to construct at a settlement.

Robot construction options
Players can choose components from a total of five different robot models:
 * Mister Handy
 * Protectron
 * Assaultron
 * Robobrain
 * Sentry bot

Robots constructed at the robot workbench are labelled "Automatron-XXX" by default, with XXX being a randomly generated number, but can be renamed like any weapon or piece of armor.

Constructing an automatron encompasses choices in seven categories. An eighth category, "Special", is only relevant for the Automatron questline and plays no role for the construction of generic robots.
 * Head
 * Torso
 * Left Arm
 * Right Arm
 * Legs
 * Voice
 * Paint

Robot parts can be freely mixed with almost no restrictions, thus enabling the player to create highly unusual but very deadly combinations. As an example, a Mister Handy torso and thruster assembly including a Tesla field and three buzzsaw-equipped appendages, combined with Sentry Bot arms wielding Gatling lasers and decked out in voltaic armor plating, results in an automatron that can single-handedly massacre entire hostile strongholds at range without needing ammunition, will devastate almost anything foolish enough to enter melee range, can move at impressive speed, can carry more than most organic companion and is small enough to accompany its master everywhere.

When building a robot the head and both arms are optional - an automatron can be finished without them, although in such a case it will usually be lacking means of inflicting damage or interacting with its surroundings, as demonstrated by the Bosun aboard the USS Constitution.
