Visitors to the Digital Content Expo in Tokyo last weekend were treated to a choreographed dance routine featuring AIST's feminine HRP-4C robot and four humans. The performance, called "Dance Robot LIVE! - HRP-4C Cybernetic Human," is the culmination of a year-long effort to teach the humanoid to dance. The routine was produced by renowned dancer/choreographer SAM-san (a member of the popular music group TRF who has worked with numerous well-known artists like SMAP and BoA), and the lip-synced song is a Vocaloid version of "Deatta Koro no Yō ni" by Kaori Mochida (Every Little Thing).
