Light based 3D printer shapes custom objects from liquid resin

Hayden Taylor, assistant professor of mechanical engineering at the University of California, Berkeley, and senior author of a paper on the technology explained that the printer relies on a viscous liquid that reacts to form a solid when exposed to a certain threshold of light. Projecting carefully crafted patterns of light – essentially “movies” – onto a rotating cylinder of liquid solidifies the desired shape “all at once.” [Source]

Engineers build robot arm with rudimentary self-awareness

As clever as robots are getting, one of the key things that separates them from humans is self-awareness. Debate rages over what exactly it means for something to be self-aware, whether robots could ever achieve it, and the ethical implications that it might dredge up. Now, researchers from Columbia Engineering have gone and done it, giving a robot arm some form of self-awareness, – at least in a rudimentary sense – which allows it to better adapt to changing conditions.
