They aren't. Humans are very adaptable, but we don't do any one thing very well. Which is why we have guns, and cars, and planes... It's much more effective to strap a gun to a purpose built machine.
It would work well for something like a cleaning/gardening drone that moves around in areas humans live in, but not so much for a robot intended to fight.
My family had wanted to put on a movie when I was over, so I had to watch the Electric State. I don't remember much of the movie, but they had drone robots that had folding propellers on their backs. Maybe they have a much of those stashed in Area 51 or something.
