Abstract

This paper proposes a system that controls and generates a humanoid robot's dance motion in real-time using the timing of beats in musical audio signals. The system tracks changes in tempo and calculate the integration value of a decibel by analyzing audio signals in real-time. It uses the information to add changes to the robot's dance motion. Beat intervals and the integration value of decibels are used to change the tempo and range of the robot's dance motion respectively. We propose a method to synchronize dance motion of robot with musical beat, changing the robot's dance motion interactively according to the input value.
