By mimicking the way that humans actually fall forward when walking, Flame comes insanely close to the real thing. Usually, walking robots are energy-hungry propositions,
but this is the first that's both efficient and stable. Inside Flame
are seven motors and a balance "organ" loaded with stability
algorithms. By measuring each step, the robot adjusts stance width,
speed, and gait on the go. In the end, kids, we're looking at the
world's most advanced and efficient walking robot.
