Toyota Develops Running Humanoid Robot: I thought it was a person in robot costume

The movements attained by this robot mirrored human actions very closely that at first I thought it was a person in a robot costume. Below is a video where Toyota demonstrates the running capabilities of the new humanoid robot. The robot takes a step every 340ms and has no contact with the ground for 100ms of that. Notice in the video how the robot remains balanced even after pushed by the person assisting in the demonstration, phenomenal and kinda scary in a way...can you imagine a whole army of these droids with weapons...seems even more plausible a reality now.
