Swimming microrobots achieve record speeds, thanks to microscale 3D printing
A robot traveling at 2 millimeters per second doesn't sound particularly fast. But when that robot is the width of a human hair, it becomes record-breaking! Purdue University researchers created the speedy swimming robots using microscale 3D printing, enabling multi-material microrobots to be fabricated with hydrogel tails that adapt to their environment.
