Settlement Protectron Defenders... would be nice, i think it would be worth the cost of perks in Robotics expert if it would allow me to build Protectron units and their charging stations for Settlement defense.
i'm not talking about anything that would increase the number of settlers in the settlement, nor am i talking about robots with any sort of advanced programming anything other than defense, no protectron Farmers or Traders, or Scrap station attendees.

I think i saw something similiar already at Nexus. So dont worry.

Not even building them, a perk that allows you to hack robots and send them to a settlement

Meh why wud you want protectron defenders anyway they svck:), now having a couple of asoultatron guards and a sentry bot or two now that wud be proper defenders:) But yeah nice idea they cud mod all of them in with diferent requirments for getting them.
