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.

The Transformer-Bot consists of cubes connected by rotating hinges. Using actuators, it can take on different shapes and move around.

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.

It looks like a toy microwave oven and can print a range of plastic things, according to USA Today, including dolls, robots, jewelry, etc. Children can use the ThingMaker app to custom-design ...
