Micro Magnet Robots Can Build Mini Super Structures SRI International, a non-profit research firm has found a novel way to control tiny, low cost magnets via electromagnetic pulses delivered to them through contact with printed circuit boards. Known as Diamagnetic Micro Manipulation (DM3), magnetically actuated micro-robots can move at speeds of up to 3cm/s, in any direction and even along curved circuit boards. As long as there’s an electromagnetic current running through the circuitry, the magnets will hold on and do your bidding. The system can host not just one magnet on a board, but dozens, which can work together or perform separate task. SRI started adding effectors which are basically little pieces of wires or other add-ons that allow the magnets to pick up, hold and manipulate materials. >>In the video , the magnets are programmed to grab, move and glue carbon-fiber sticks. Eventually, they built a 29-centimeter-long truss capable of supporting up to 2 kg. Our vision is to enable an assembly head containing thousands of micro-robots to manufacture high-quality macro-scale products while providing millimeter-scale structural control. The company believes these micro robots could someday power entire micro factories. youtu.be/uL6e3co4Qqc
