"Japan's National Institute of Advanced Industrial Science and Technology (AIST) is back with the mighty impressive HRP-4 humanoid. Created in partnership with Kawada Industries, this 151-centimeter (5-feet) tall, 39-kilo (86-pound) walking followup to the HRP-4C, HRP-3 and HRP-2 robots (pictured in the background) was developed to help take over manufacturing duties from a rapidly aging Japanese work force. The highly mobile HRP-4 features 34-degrees of movement with AIST proprietary control software running on a Linux core. Things get weird at the 5:30 mark of the video embedded after the break when a human enters the stage for a good ol' fashioned stare down. Probably has something to do with his hot wife."^^<http://www.w3.org/2001/XMLSchema#string>
