Surprise someone with robots today, not so easy. But researchers from Stanford University have made a good attempt: they set up a tiny bots, able to lift things more than 100 times heavier than their own weight. According to the scientific journal New Scientist, the tiny robots are the result of scientists ' attempts to mimic the behavior of geckos.

Surprised not only that the robots can move relatively heavy for the goods: they are able to do this even on vertical surfaces. Thus, their "legs" contains a special adhesive that allows the bots to stay on the wall even if they are carrying heavy loads. At the same time, this adhesive composition is easily unstuck from surfaces during movement. And as you can see in the video below, traffic bots also mimic the natural movement of worms and some animals.

One 9-ounce bot (in this video Stanford 2006-era StickyBot) can carry a weight of one kilogram, while a surprisingly small 20-milligram bot is able to pull a 500-milligram cargo (a small paperclip). But the most impressive robot is a 12-gram beast under the name μTug that can drag load 2000 times heavier than its weight. As noted by researchers from Stanford, in an interview with New Scientist, it's about the same as if a man dragged behind a blue whale.
