A team of engineers created a four-legged robot called HyQ, and it "ninja walks" on two legs across narrow bridges, according to a video published Friday on YouTube.

Weighing 90 kilograms (198.4 pounds), this "ninja" robot can balance itself on a support line and recover from minor slip-ups and shakes. Using a balance controller, the robot adapts to changes in posture, including varying heights achieved via adjusting the angle of its legs' joints.

To walk across narrow, 6-centimeter (2.3-inch) bridges of up to 1.5 meters (4.9 feet), the robot does a "ninja" walk — using a motion generator to walk the narrow line with fantastic precision.
