It would be cool to make companions to come with us on our journeys thru the wasteland
Or make companions to help with the settlements

Not implausible we can deploy sentry guns, one other options is to repair destroyed robots, or disable and reprogram them.

If not, I'm sure a mod will fill this need just like Robco Certified did

on a slightly related note does anyone else hope Mr. Gutsies have the same voice actor?(loved Cerberus )

We may or may nor be able to build our own robotic companions but what I really hope we can do is upgrade and repair Codsworth to be more combat-effective.

Maybe Codsworth isn't a fighter. May be he just hangs back giving you tactical advice.

"Go for the eyes, Boo Howard!"

I like the idea of having customizable robot companions that make to your liking and choose what kinda weapons it uses to compliment your playstyle, such as choosing between having something like Mr.Gusty (Offensive for helping with fighting) Mr. Handy(Repairs equipment and can act as a mobile workbench like ED-E) or some sort of healing type robot similar to those medical eyebots found in Lonesome Road.

That would be cool. It could be in the game with all the changes they've made. There was a robotics expert perk. It could have something to do with that.

I think it'd be better if we could repair/salvage parts and add robots to our towns defences.

Now in the Xbox conference he had a character named Phil Spencer with a first and last name

I just really want a protectron or securitron as a companion. I've wanted one since I first learned you could buy one of Tinker Joe's robots.

edit: forgot to include protectron

Yea the protectrons look pretty cool in Fallout 4, I wouldn't mind one as a companion.

Honestly, I'm hoping for a pack brahmin or a cargo bot to off-set my tendencies to grab anything and everything that looks like it might be remotely useful sometime, somewhere, down the line.
