Robotics powered by muscle cells: another step forward  "Most robots are powered by electrical motors that are big, bulky, heavy, and if they break, you have to replace them. Animals, on the other hand, use a biological motor—a muscle—that also requires electricity, but is far more efficient and, given a chance, can repair itself. We're just starting to be able to manipulate biological structures like these..."  (courtesy of University of Illinois at Urbana-Champaign)
