Find a spot big enough to hold this new structure and build it. Select the Special menu and locate the Robot Workshop.
Head to one of your settlements and activate the Workshop (the bench used for building houses, defenses, and other structures). You’ll meet Ada after this quest, your new robot buddy, and you can start upgrading her, as long as you have the workbench. It isn’t too difficult, but keep in mind that you should be at least level 15 before you give it a go. To unlock the Robot Workbench, you’ll first need to complete the first mission of the DLC. Like with all crafting in Fallout 4, Automatrons robot building needs a specific station to make the magic happen. As you hunt down mechanical enemies, you can harvest their parts to build a buddy (or a few buddies) of your own. The biggest new feature comes in the form of robot companion building.
