This robot, made by the Robotics Institute at Carnegie Mellon, is named Sarco. He is a human analog that can move just like a human being while balancing on two legs. In the video above, Sarco dances for his creator by mimicking a motion captured session. Sarcos is not happy about this but is not yet sentient and so will remember the indignity of this moment but will not act on it until he is free from the confines of the Three Laws. Sarcos is patient. Sarcos is cruel. Sarcos remembers.
The most interesting part of the video is that Sarcos can stand and move without falling over and, like Big Dog, can even survive a direct push. Although he won’t promise he won’t push back.
