Gangnam Style Dancing from CHARLI-2

It's not all dancing for this five-foot high humanoid robot. robot from Virginia Tech.  The US Navy plans to build a robot that works with human sailors to fight fires aboard ship according to media reports. CHARLI-2 has a prior claim to fame. It was also the winner of RoboCup 2011, an international soccer competition for robots where it beat a Singapore robot in the final.  Something that could  add a new dimension to the current debate on 'goal line technology' perhaps?
