The RoboTutor is a NAO robot programmed to teach classes. While the NAO is an already existing robotic platform, created by Aldebaran, the software that runs on it was developed by the TU Delft.
The goal of the RoboTutor is not to replace teachers, but to assist them during classes. Right now, the robot can only tell a story and ask short questions to pupils. The aim is to program the robot so that it can present a fully interactive lesson.
