Researchers from Advanced Industrial Science and Technology Institute of Japan (AIST) just released this new video of the HRP-4C Miim robot that they develop. The human-like robot is now able to walk smoothly, its (or her?!) knees are stretched by the vertical movement of the waist, the single-toe supporting realizes longer strides and the legs perform the swing motion of the human equivalent. Technical details were recently presented at IROS 2011. You can find more info at AIST official Web site and Intelligent Systems Research Institute.
