Greeting!
As you probably know in Fallout 4 we will visit the famous Institute mentioned in Fallout 3, this organization is known to possess advanced technology and even created a true artificial intelligence (AI) and androids.

That got me thinking, what if we will have robot or robots as companions?
Maybe we even can upgrade them with our science and repair skills (i am positive these two skills are still present in Fallout 4).
For example science skill will be useful to upgrade robot's software part (more efficient/complex decryption algorithms resulting in disabling higher level alarms, hack more complex computer terminals, improve it's target acquisition software resulting in improved robot's accuracy, recoil compensation software for automatic firing)
And repair to upgrade robots armor, maybe even swap it's metal legs to chassis or even some kind of anti-gravitational engine like we saw in a trailer on USS Constitution ship, upgrade it's weapon to rocket-launcher,flame-thrower or grenade launcher. Maybe even improve it's actuators and mount a chainsaw or a pneumatic hammer on them, swapping to a more potent/more efficient nuclear battery.
Of course it will need to be balanced, mounting rocket launcher should require rare parts, high skill and even specific perks.
Not only it will be fun, it will allow of existence of essentially non combat characters in the game.
I started non combat char's several times in fallout 3 and new vegas but i could not go through the game without lvling up and using at least one of my combat skills.
So, what your thoughts on this idea?
