Researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal 'metasheet' but, with a jolt of electricity, morph into preprogrammed 3D shapes and crawl.

With technology moving at the pace it is, engineers of all shapes, sizes, and projects are showing the world what’s possible. Today, you’ll learn how to build your very own off-road, rugged, and ...
