New Korean Running Robot Can't Catch Japan's

A small South Korean company has become the second in the world to develop a humanoid robot that can RUN. Called RX, the robot can run about 500 meters per hour (the Japanese running robot, ASIMO, can hoof it at 3 kilometers per hour). The robot's inventors say that RX is made with "modulated blocks," which, like Legos, can be re-used for other types of robots.
