A press release from Sony claims they have developed the world's first fully autonomous humanoid robot with internal power and control that is capable of running. The robot is an upgraded version of the Sony QRIO, a robot we've seen before. The robot uses a control theory called Zero Moment Point (ZMP) and in addition to running is capable of other extreme motion that involves one or both feet leaving the ground such as jumping. Additional photos of QRIO in action can be found on the Japanese PC Watch site. There's also a Slashdot discussion about QRIO.
