Bionic Robots

Researchers at the University of California Los Angeles (UCLA) have developed microscopic robots made of silicon that are powered by muscle tissue. The microbots were created by allowing the self-assembling cells to grow on a tiny robotic structure, less than one millimeter long.

Each structure had two legs with feet, and the cardiomyocytes, muscle cells from (in this case) a rat's heart, grow in an organized manner on the silicon superstructure (i.e., the skeleton). Since the muscle cells grow on their own, there is no need to graft muscle tissue to the superstructure. The structure can then be powered by placing it in a system charged with glucose, similar to a living body. The muscles then contract in an organized manner, causing the microbots to "walk."
