Rihanna and the Titan Robot dancing together

What a surprise to see two altered Titan robots dance beside Rihanna, the singer! It happened at the Echo Music Awards in Berlin, Germany. Rihanna interpreted her song "Rude Boy". More than one human in the hall would have certainly wanted to change places with these robots :-) http://www.youtube.com/watch?v=b8eiF3I4t8I
