U.S. scientists say stretchable electronic fabric could help robots become more human, and humans more robotic.

The Argus II bionic eye "could change lives," according to the health body.

Students from ETH Zurich are developing an exoskeleton for paraplegics that will keep them from struggling on uneven terrain.

German engineers also design lightweight robot butterflies and use insects as models for industrial robots.
