Claytronics.......... new basic fundamentals Nano-technoligy

A big robot developed by catoms
Catoms are non other than nano Programmable matter, are small scale robots which able to communicate with each other and able to regenerate a  new large scale robot.                                                                                                                                                                                             

A car simulation: real picture

catoms are connected each other

Catoms create molecular structure
