Robots are getting simpler all the time.

If that statement sounds backwards, consider this: as we continue to cram ever-more-powerful electronics into tinier and tinier containers, the number of things we can do at home, ourselves, with our everyday appliances and devices is growing exponentially. The same technology that makes it possible to squeeze a GPS, tilt sensor, camera, and wireless Internet connection into your cell phone also lets researchers design miniaturized robots that really pack a punch.

For scientists, knowing that a robot brain doesn’t need to take up more room than a postage stamp means they can design robot bodies out of the most unexpected materials: soft polymers, folded paper, fabric that can bend and ...
