Gerridae are a family of long-legged bugs commonly known as water striders that are able to run on top of the water's surface. Chinese scientists have developed an aquatic microrobot that mimics Gerridae.
The robot has a body about the size of a quarter to which ten water-repellent, wire legs and two moveable, oar-like legs are attached. While the 10 long legs extending from either side of the robot's body keep it afloat, the two shorter, centrally-located, oar-like legs powered by two miniature motors propel it across the surface of the water.
