SRI International has unveiled micro robots that can actually put together mechanical assemblies and electronic circuits. Diamagnetic Micro Manipulation (DM3) utilizes small magnets that move under a circuit board to get the micro-robots to follow a set pattern based on a set of preprogrammed instructions. They may look miniscule, but these micro bots can move up to 1-foot every second to transport micro manufacturing supplies. Continue reading for the video and more information.
According to SRI and Dvice, "DM3 can be used for prototyping parts, electronics assembly, biotech lab-on-a-chip experiments, and assembling small mechanical systems in hostile environments. Eventually they plan to scale up the technology, by developing a manufacturing head containing thousands of the little buggers that can build much larger assemblies."
