Scientists at the University of California, Los Angeles have developed Tiny Robots powered by living muscle. In one experiment a tiny device that moved on its own as the cells contracted was created by growing Rat heart cells onto microscopic silicon chips. Jianzhong Xi, Jacob Schmidt and Carlo Montemagno of the University of California Los Angeles writing in the journal Nature Materials, said it is possible to make such devices, starting with a single cell "seeded" on a specially treated silicon chip. "A microdevice with two 'legs ' extending from the body at 45-degree angles; each leg had a 'foot' extending at a 45-degree angle," was also developed.
