Take a look at that picture. That is a massive column of robots all itching to fire lasers at you. Well ok maybe not lasers but they can shuffle into specific formations on command which yeah isn't quite as exciting. It's still the first step though towards everyone having their own robot army.
At the moment just mind dulling tasks but maybe in the future they will be able to do better things like slap Scotty around the face when he gets to close to my Mum or bring me food.
