MiReLa: a musical robot

A music based robot-human interaction system is presented. A musical language was developed to make robot-human interaction reliable in noisy environments. This language can be whistled and played on simple instruments. Mobile phones and PDAs can also be used to generate phrases in this language. It was implemented as part of a "society of agents" where each agent helps the others, and all of them together make a mass of skills that grow in power and efficiency.
