KNOW WHEN TO FOLD: An handout image provided by the journal Science showing a self-folding crawling robot in three stages. In what may be the birth of cheap, easy-to-make robots, researchers have created complex machines that transform themselves from little more than a sheet of paper and plastic into walking automatons.
WASHINGTON: It starts out laying flat, like a sheet of paper. Then it springs up, almost lifelike, and folds into moveable parts much like origami art. And then it crawls away.
This new kind of robot could someday be used in space exploration, to slide into collapse sites to aid search and rescue, or to speed up manufacturing on assembly lines, experts said.
