Germany: Watch robots dance Gangnam style

Just as visitors at the Hannover Messe probably thought they'd seen it all, engineering and electro-mechanic company Faulhaber pulled some dancing robots out of their hat on Monday. The robots danced away Gangnam style, while visitors marvelled at them and took pictures. The Korean company Dongbu Robot designed the dancing bots, while the German company Faulhaber supplied the motor. A High-performance HerkuleX servo module serves as the controller for the “nerves and then muscles.” The module consists of a motor, a communication interface, an encoder and a high-performance gearhead, and can be purchased separately. The engineering behind humanoids – robots that move like humans – is incredibly complex and still in the developmental stage, so currently the machines are mainly used for research and as toys.
