Pulling the perfect pint -- manually or otherwise -- seems to be something of a long standing obsession across the pond, and more than one beer-pouring robot and device has been whipped up in occasion of this grand pursuit. The latest, Hermann, is the fruit of the efforts of one Professor Thomas Weber and his 23 scients students at the German Technical University of Darmstadt, whom set out to design a robot that would cost under $90 US that could pull the perfect pint. Can Hermann really do it? Weber says so -- but he's not sharing sharing much in the way of the secret of their success. (The device pictured is David Stevenson's homer, from 2004.)
