You may recognize the Einstein robot from a WIRED magazine cover earlier this year. Here's a video of the Einstein Robot in action. As Hanson Robotics describes, "The big deal with Albert Hubo is the battery-powered untethered walking body. The Albert Hubo is the first ever walking robot with humanlike expressions. Our Frubber material makes this possible, because it requires MUCH less force to move into facial expressions than do previous materials--less than 1/20th the force and energy than the softest animatronics materials, accordingÃŠto published tests. ÃŠThis means that the Albert head can run for hours on AA batteries, so it can be mobile and mount on a walking robot body. The expressions are lifelike--as can be seen at in this movie."
