Sarah Bergbreiter is an assistant professor of mechanical engineering at the University of Maryland, and she and her team build tiny robots.
Just how tiny? Bergbreiter calls it "ant-scale," but said, "That's really just a PR term. Our robots are built on the millimeter scale, less than 1 centimeter."
This all happens out of the university's Microrobotics Laboratory, where they develop technologies that aim to make tiny robots that not only function properly, but will one day be as handy and useful as large robots.
