These Robot Claws Are Made From Paper

Robots made of … paper? Researchers at Carnegie Mellon’s Human-Computer Interaction Institute have developed a pretty neat way to bring plain old paper to life. The team used an inexpensive 3D printer to apply a thin layer of conducting thermoplastic, a material that becomes pliable when warm, but regains its original, hardened shape when cool.
