"The HRP-4C robot and the open-source ART-Linux distro (see more
farther below) were developed by AIST's Human Robotics Group (HRG).
ART (Advanced Real-Time) Linux has been used in a variety of
humanoid robot prototypes from the Japanese government-backed
HRG/AIST, says the group. The newest HRP-4C model announced earlier
this week has been a hit on YouTube (see below). Designed to look
like a young Japanese woman, the robot stands (and walks) about
five feet, two inches (158 centimeters), and weighs about 95 pounds
(43 kilograms)."
