The project "Stage and robotics: interactions and interrelations" aims at constituting an interdisciplinary platform that brings together engineers, computer scientists, artists and researchers in the performing arts around the question of the sociability of both robotic devices and theatrical practice. Through the pooling of knowledge and languages, as well as the setting up of creation workshops and observation protocols, we wish to investigate the relational and dramaturgical potential of the robot on stage in its interactions with the actor and the spectator.
