As reported on Engadget. BY STEVE DENT It turns out that robots don’t need to be BigDog-sized to be freaky. Scientists at the University of Illinois have created one a mere centimeter (half-inch) in size built on a 3D-printed hydrogel backbone. The “ew” part is what powers it: a strip of skeletal muscle cells triggered by an electric current. Previous biobots built with heart tissue couldn’t be controlled, but muscle cells can be activated with electric pulses and made to “walk” at…
