Geckos and cockroaches can do amazing tricks thanks to their unshaven legs [Science]
posted July 3 2012 16:02.27 by Giorgos Lazaridis

Scientists filmed geckos and cockroaches while trying to escape predators. The experiment included a "walk on the board". They had to run on a short and narrow trail which eventually leads to a cliff... Amazingly, they both flipped up-side down with their back legs like stuntmen can never do!

Then they shaved their back legs and ran the experiment once more. Surprisingly, they lost this ability of the acrobat. Inspired by this feature, they developed robots that can do exactly the same thing.
