Dartmouth College researchers have created a robot so small that 200 of them could fit on the tip of your finger. The tiny machine crawls like an inchworm across a grid at the breakneck speed of 200 microns per second. Its goal: to fix really little things. Dartmouth engineer Bruce Donald says swarms of such devices could one day repair circuitry in computer chips.
