Imitating human dance motions through motion structure analysis

Abstract
This paper presents the method for importing human dance motion into humanoid robots through visual obser- vation. The human motion data is acquired from a motion capture system consisting of 8 cameras and 8 PC clsters. Then the whole motion sequence is divided into some mo- tion elements and clusterd into some groups according to the correlation of end-effectors' trajectories. We call these segments as 'motion primitives'. New dance mo- tions are generated by concatenating these motion primi- tives. We are also trying to make a humanoid dance these original or generated motions using inverse-kinematics and dynamic balancing technique.
