UPDATE 13 April 2012, 12:02 p.m. A notice posted on the U.S. Federal Business Opportunities website confirms that DARPA has selected Boston Dynamics as a "sole source" to develop and build the humanoid robots that the software teams will use in the DARPA Robotics Challenge. "Of the few existing humanoid robots," the notice says, "[Boston Dynamics] was deemed to be the sole viable supplier for providing the necessary robotic platform capability within the specified timeframe." Boston Dynamics will build 8 identical humanoids, which will be based on PETMAN (see below an exclusive photo we obtained) and Atlas, robots that the firm build for the U.S. Army and DARPA, respectively. The result is expected to be "a one of a kind humanoid robot with state of the art capability."
Just as we were getting ready to put together a big long post speculating on which humanoid platform DARPA would select for their newest Robotics Challenge, a video posted yesterday to the official DARPA YouTube channel has made all of that completely unnecessary: to the surprise of nobody, it's going to be a derivative of Boston Dynamics' PETMAN/ATLAS humanoid robot.
