The Hindu (Aug. 30) -- Scientists have used origami to create a low-cost, crawling robot that uses very little energy to move around. “The robot uses origami building blocks to mimic the gait and metameric properties of earthworms and directional material design to mimic the function of the setae on earthworms that prevents backward slipping,” says Sameh Tawfick, a professor of mechanical science and engineering at Illinois.
