Claytronics : Turning dream into real<br />

Transmission and reception of sound energy by telephone was followed by a revolution in electronics<br />

and its digitalization. Pictures along with sound were then transported successfully from<br />

one place to another along with miniaturization of electronics. Such developments inspire scientists<br />

and engineers to think about human teleportation. Teleportation is the transfer of matter<br />

from one place to another instantaneously, either by paranormal means or through technological<br />

artifice. Matter teleportation, however, is still a day dream, but along these lines researcher have<br />

come up with a new science called Claytronics. The idea is to create a small robot of a few<br />

millimeters which can organise itself into a shape that is determined remotely.<br />

Claytronics is an emerging field of engineering, drawing on nano technology and computer engineering.<br />

Claytronics or programmable matter refers to an assembly of tiny components called<br />

claytronic atoms or catoms, which could assume the form of any object, depending on the<br />

programs controlling the Claytronics. This term also refers to the art of making clay caricatures of<br />

public figures, begun in 1996 by an Indian Charuvi Agrawal.<br />

CLAYTRONICS is a concept that<br />

combines nanotechnology and<br />

modular programmable robotics to create<br />

what is also called programmable<br />

matter, programmable grit, dyn amic<br />

physical rendering or synthetic reality.<br />

Very small components, called<br />

claytronic atoms or catoms, have the<br />

ability to move and morph into shapes<br />

controlled by a communication network.<br />

Claytronics is a form a progra m-<br />

mable matter that takes the concept<br />

of modular robots to a new extreme.<br />

One of the primary goals of Claytronics<br />

is to form the basis for a new media<br />

type, pario. Pario, a logical extension<br />

of audio and video is a media type used<br />

to reproduce moving 3D objects in<br />

the real world.<br />

Claytronics is a name for an instance<br />

of programmable matter whose p rimary<br />

function is to organize itself into<br />

the shape of an object and render its<br />

outer surface to match the visual appearance<br />

of that object. Clayt ronics<br />

is made up of individual components,<br />

called catoms—for Claytronic atoms—<br />

that can move in three dimensions (in<br />

relation to other catoms), adhere to<br />

other catoms to maintain a 3D shape,<br />

and compute state information (with<br />

possible assistance from other catoms<br />

in the ensemble). Each catom is a selfcontained<br />

unit with a CPU, an energy<br />

store, a network device, a video output<br />

device, one or more sensor s, a<br />

means of locomotion, and a mec hanism<br />

for adhering to other catoms.<br />

A Claytronics system forms a shape<br />

through the interaction of the individual<br />

catoms. For example, suppose<br />

we wish to synthesize a physic al<br />

“copy” of a person. The catoms would<br />

first localize themselves with respect<br />

to the ensemble. Once localized, they<br />

would form an hierarical network in a<br />

distributed fashion. The hiera rical<br />

structure is necessary to deal with<br />

the scale of the ensemble; it helps to<br />

improve locality and to facili tate the<br />

planning and coordination tasks. The<br />

goal (in this case, mimicking a human<br />

form) would then be specified abstractly,<br />

perhaps as a series of “snapshots”.<br />

or as a collection of virtual deforming<br />

“forces”, and then broadcast<br />

to the catoms. Compilation of the<br />

specification into local actions would<br />

then provide each catom with a local<br />

plan for achieving the desired<br />

global shape. At this<br />

point, the Catoms would<br />

start to move around each<br />

other using forces generated<br />

on-board, either<br />

magnetically or electrostatically,<br />

and adhere to<br />

each other using, for example,<br />

a nanofiber-adhesive<br />

mechanism. Finally,<br />

the catoms on the surface<br />

would display an image,<br />

rendering the color and<br />

texture characteristics of<br />

the source object. If the<br />

source object begins to move, a<br />

concise description of the movements<br />

would be broadcast allow ing<br />

the catoms to update their pos itions<br />

by moving around each other. T he<br />

end result is the global effec t of a<br />

single coordinated system.<br />

The core concepts in Claytronics<br />

are hardly new; from science f iction<br />

to realized reconfigurable rob ots to<br />

proposed modular robots, scien tists<br />

and writers have contemplated the<br />

automatic synthesis of 3D objects.<br />

However, technology has finall y<br />

reached a point where we can for the<br />

first time realistically build a system<br />

guided by design principles which will<br />

allow it to ultimately scale to millions<br />

of sub-millimeter catoms. The resulting<br />

ensemble can be viewed as either<br />

a form of programmable matter suited<br />

for implementing pario or as a swarm<br />
