Self-Folding Origami

Robert Wood of Harvard University, Daniela Rus and Erik Demaine at the Massachusetts Institute of Technology take us to a new level of robotic creepiness with self-folding origami.  The device is able to morph itself into new shapes using shape-memory alloys that line the edges of triangular modules.  Each module also sports a strong magnet that holds the final form after a module has executed a desired fold.
