Researchers Hope to Mass-Produce Robots on a Chip
Tiny robots the size of a flea could one day be mass-produced, churned out in swarms and programmed for a variety of applications, such as surveillance, micromanufacturing, medicine, cleaning, and more. In an effort to reach this goal, a recent study has demonstrated the initial tests for fabricating microrobots on a large scale.

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.
