The tiniest mobile robot ever has been created by US researchers. It is a sliver of silicon one hundredth of a millimetre thick that can be precisely steered like a remote-control car to move in any direction across the surface of a special plate.
Powered by a grid of electrodes underneath a surface layer and steered by its tiny silicon paddle, the bot crawls around at a speed of about 200 micrometres per second and can push specks of dust, or other “dead†robots.
Yes, there is a video.
