The bots that bucked the humanoid trend at DARPA's challenge

Humanoids are supposed to be best suited for a world that's engineered for humans. They can climb stairs, open doors and drive cars. At DARPA Robotics Challenge, most of the participating humanoids succeeded in completing those tasks, but when it came to walking, they were clumsier than the species they were designed to emulate. Getting a machine to put one foot in front of the other has been a priority for roboticists for decades. Bipedal locomotion would presumably make it easier for robots to navigate a man-made world and perhaps make them more relatable.
