I am making a mod, and what i'm asking for help getting is pieces of code necessary for the mod. i now need one last thing: a small robot like this:

only with top part as a turret and gun as small weak sniper.

if done i worship the creator of the mod.
they will get credit along with creators of code that i used.
P.S: all hail this guy:

One: How big do you want this guy? Dreadnought sized or actual size?

Two: That bobbing head thingy, I assume that isn't a requirement, or is it?

1 day after post, image its gone.

Turrets are more than possible, a fact.
I'm afraid Kyred didn't get enough credit about his hours of turret developing...

One: Half dreadnought size

Two: Not required, but it would be nice

Image was gone when I looked, right click on it and follow some kinda URl and you'll see it.

OP doesn't know how to hotlink images.
