Communication of musical expression from mobile robots to humans: recognition of music emotions by means of robot gestures
Birgitta Burger, TMH and Musikwissenschaftliches Institut der Universität zu Köln
The goal of this master thesis was to develop a robotic system that can behave in an emotional way. We designed a 3-wheeled Lego Mindstorms NXT robot, whose aim was to display emotions in music performance by performing movements.
Based on literature about emotions in music, movements performed by instrumental musicians to express emotions and a software agent that displays emotion in music by different gestures, characteristic movements have been compiled and programmed. The three emotions happiness, anger and sadness have been implemented in that way. One of the main tasks was to handle the limited degrees of freedom, due to the Mindstorms NXT system.
General results from behavioral experiments show that emotions can be synthesized, displayed and communicated by an artificial creature, also in constrained circumstances.
