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.

See how an autonomous robot created a shock-absorbing shape no human ever could -- and what it means for designing safer helmets, packaging, car bumpers, and more. Inside a lab in Boston University's ...

Fidget poppers are an example of "bistability," as the popped circles rest in one of two stable states. Purdue University researchers have taken this idea to its extreme, building robots that can be ...
