Really, really small robots that swim
When you’re just a few microns long, swimming can be difficult. At that scale, water’s got the viscosity of honey and momentum can’t reliably maintain forward motion.
To beat these obstacles, a team of researchers at the Georgia Institute of Technology has used complex computational models to design swimming micro-robots that could one day be used in drug delivery, lab-on-a-chip microfluidic systems—and even as micro-construction robots working in swarms.
