For building the robots and weapons, which perks (if any) are needed. I saw one YT vid that mentioned needing the Robotics Expert Perk, which is a perk I never get. So if you wanted to max out robots and weapons and armor you build, which perks are required?

I'm imagining a symbiosis, or a synergy between the perks and Automatron, rather than a dependency.

/me crosses fingers

Max rank science, armourer and level two in robotic expert

Depending on how lucky you are you should be able to loot most of the body types throughout the Automaton storyline but you are probably going to have to build all the attachments (armour, weapons, head etc.) especially the high up ones yourself.

Oh and you also unlock all mods at the end of the storyline if you want to wait and see what perks/parts you need to make the robot you want to make.

Two levels of Robotic Expert, easy to get...

(Come on Deathclaws, get a taste of my Gauss...)

The biggest problem with RE is the 8 INT requirement. Especially if you were playing a character depending on Idiot Savant and have a low INT.

I'll have to make a special high INT character to be my super duper robot master.
