Bacteria-scale robots that can run for months without human control are no longer a lab fantasy. Researchers have now built fully programmable micro-machines, smaller than a grain of salt, that can ...

A new study led by Penn State researchers shows for the first time how sound waves could function as a means of controlling micro-sized robots. UNIVERSITY PARK, Pa. — Animals like bats, whales and ...

Scientists have designed swarms of microscopic robots that communicate and coordinate using sound waves, much like bees or birds. These self-organizing micromachines can adapt to their surroundings, ...

Figure 2: By using smaller servo drives, robots have less dead weight to deal with, reducing their wear-and-tear. The ongoing trend of micro-sized servo drive technology is driven by Moore’s Law and ...
