MIT Thinks This 'Smart Sand' Can Be Used To Clone Solid Objects

MIT Smart Sand

MIT is creating ‘smart sand’ — made of tiny robotic cubes — that will be able to surround an object, map its form, and then replicate it.

We first heard of the project at NPR.

The minuscule cubes contain a microprocessor, magnets for sticking to each other, and a battery. But size is the biggest issue, as the current smart cubes are still too large for anyone to call granules of sand.

The theory is that an object — say a toy car — would be tossed into a bag containing the little computers. The cubes are then able to interact with each other, and can recognise when they’re pushed up against a foreign object.

A digital silhouette is mapped out, and the data is transmitted to another group of cubes, which will then link together to replicate the object. Remove the extras, and you’ve got a fabricated match of the toy car.
