Army of Flea-Sized Robots to Do Our Bidding in the Future

Researchers are working towards mass-producing a bunch of tiny, flea-sized robots to do our bidding. Bring on the miniscule robot helpers!


I-SWARM robots could be used for everything from cleaning to surveillance to medicine to manufacturing. The trick to building useful little robots is to put the entire robot on a single circuit board.

The researchers, from institutes in Sweden, Spain, Germany, Italy, and Switzerland, explain that their building approach marks a new paradigm of robot development in microrobotics. The technique involves integrating an entire robot - with communication, locomotion, energy storage, and electronics - in different modules on a single circuit board. In the past, the single-chip robot concept has presented significant limitations in design and manufacturing. However, instead of using solder to mount electrical components on a printed circuit board as in the conventional method, the researchers use conductive adhesive to attach the components to a double-sided flexible printed circuit board using surface mount technology. The circuit board is then folded to create a three-dimensional robot.

The resulting robots are very small, with their length, width, and height each measuring less than 4 mm. The robots are powered by a solar cell on top, and move by three vibrating legs. A fourth vibrating leg is used as a touch sensor. As the researchers explain, a single microrobot by itself is a physically simple individual. But many robots communicating with each other using infrared sensors and interacting with their environment can form a group that is capable of establishing swarm intelligence to generate more complex behavior. The framework for this project, called I-SWARM (intelligent small-world autonomous robots for micro-manipulation) is inspired by the behavior of biological insects.

Sounds awesome yet also a little creepy. Not that I'm afraid of an army of flea-sized robots spying on me but, well, I am. [Physorg]



I assume when you say "our" bidding, you mean "our" as in the CIA, FBI, NSA, RNC, DNC, IBM, AT&T, Comcast, Cox, RIAA, MPAA, PTA, NEA, WHO, World Bank, UN,...

Somehow I very much doubt flee sized robots will ever be doing "my" bidding.
