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.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
