Since the first crude automatons running on clockwork mechanisms, mankind has been working to build the perfect artificial copy of ourselves for centuries. But what's a more accurate recreation of a human? A robot made of various components and wires all cobbled together? Or one made of billions of tiny robots all working together like the atoms that make up everything around us?


Researchers at Harvard University, clearly inspired by the idea that one day life can be recreated using countless tiny robots, have been developing and building their Kilobots en masse for years now. Exemplifying the idea of team work, the Kilobots started off with just twenty-five units all working together to accomplish a task, then a hundred, and now a thousand.

Controlled by sophisticated swarm software and built-in infrared sensors on each unit, the Kilobots are limited in their functionality on an individual basis. But when they start working as a team, using simple rules for moving around and interacting with each other, they're able to accomplish more significant tasks. Of course, forming the shape of a simple star might not be the official start of artificial intelligent life, but what we're seeing here are some important baby steps as man strives to finally build the perfect robot butler.
