Suuuure.  They’re for “building things.”  Certainly not for hunting down the last few rogue survivors of a post-apocalyptic wasteland.  All joking aside, I’d be a bit nervous to enter a structure built by these things.  I mean, I realize that a lot of the stuff we use is made by robots anyway, but…I don’t know.  It just weirds me out a little.  On that note, this video is cooooooool!
