A robot powered by heart muscles

You can't accuse this robot of not having any heart.

A group of South Korean researchers from the Nano/Micro System Laboratory at Seoul National University has created a miniature robot powered by living heart tissue. The "microrobot" was designed to be injected into the human body and loaded up with a dissolving agent to clear blockages in arteries and other biological systems.

The scientists created the miniature robot by growing heart muscles from a rat on an elastic polymer called polydimethylsiloxane (PDMS).

As this video shows (AVI format), the robot scoots along on its three legs, powered by the twitching heart muscles. The self-powered robot can walk continuously for 10 days, and the polymer it's made out of is biodegradable.

Truly some amazing stuff. We're a little bummed we didn't find out about this robot sooner, or it would have been a pretty high seed in our ongoing battle of nonviolent robots.
