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 ...

SYDNEY, March 28 (Reuters) - A team of biomedical engineers in Australia have developed a small flexible robot that can be used to 3D print biomaterials directly inside the human body, in the hopes of ...
