History

QTrobot was developed by LuxAI, a startup spun out of the University of Luxembourg, founded by Aida Nazarikhorram and Pouyan Ziafati. The goal was designing an expressive social robot for use in therapy, education, and research. Applications included learning support of children with autism and experiments in human-robot interaction. LuxAI started building QTrobot in 2016, finished a final prototype in mid-2017, and the following year began trials at various centers in Luxembourg, France, Belgium, and Germany. LuxAI plans to conduct longer-term trials, studying the robot’s impact on social competence, emotional well-being, and interaction with people.
