Well, some of you own a 3D printer. While you might be always marveling that it is the greatest wonder of technology, you also need to consider this: a tiny coin sized robot. These robots will beat the D printers in a clean sweep. The computer scientists of the great University, Harvard, have built an army of 1,024 robots that join to form different shapes. Well, if you don’t get it, just think of how the birds fly in formation or how ants link to form bridges.
These robots also behave in the same way and are called Kilobots. After reading this, you might be wondering how they communicate. Here goes the answer: they use infrared light for communicating by moving from one place to another based on the instructions given.
Four robots mark the origin to form each object. Later, the secondary Kilobots move into place slowly based on the transmitted image. The image which you can see is a work which consumed a lot of hours. By doing this, the whole process is simplified! Click here to view more details on the Kilobot.
