A music dancing robot based on beat tracking of musical signal

The paper proposes a dancing robot based on the beat tracking method. The robot can carry out different actions when receiving different musical signal input. The dancing poses are vivid and lifesome, and development of the robot is helpful to enhance intelligence of the traditional creational robot, which exerts a striking influences on the conventional toy market. In the paper, the design of the robot is described and the most parts of the paper focus on the beat tracking technology. Three kinds of reduction methods, containing high frequency content (HFC), spectral difference (SD), and combination method, are applied to beat tracking. After experiments the results are analyzed, and we find that the combination method is most suitable reduction method in our research.
