What hath science wrought today? Weather control? No. Flying car? Keep dreaming. Robot cat? You bet! Read:

Dubbed the "cheetah-cub robot," scientists at the Swiss Federal Institute of Technology in Lausanne modeled it after a common housecat, with strings replacing the tendons in its legs. Flexible knees allow it to bound over steps and other small obstacles.

The robot can run at speeds of up to 3.1 miles per hour. Each second, it can travel seven times the length of its body, and it's the fastest four-legged robot ever created that weighs less than 65 pounds.


Now see it in action.
