What if you marry Kinect with a Roomba vacuum?
OK, so a Roomba robotic vacuum is, by it's very nature, hands free. But what if you wanted to direct it now and then, but still, heaven-forbid, touch it? You can give it a Kinect hack interface.
So it is with this demo video by "Ogutti." Is this a practical hack? Maybe not. Entertaining and cool? Yes and definitely.
