Educational robotics has already found wide application in teaching at all levels of education. Teachers often use it as a motivational factor in teaching programming, but also in interdisciplinary activities. Research studies in this field have shown that it is particularly well suited to encourage the development of computational thinking skills. Within the Erasmus+ FERTILE project, a methodology has been developed for designing projects combining educational robotics with art, which should use blended learning and support the development of students' computational thinking. In training sessions in several European countries, this methodology has been introduced to teachers with the aim of supporting them in designing engaging and beneficial activities for their students.

In this paper, we present the methodology together with a tangible example of its use - the Robotic Nativity project, which combined educational robotics not only with music education but also with other school subjects. The project was designed by one of the participants in the teacher training and was tested with students of a lower secondary school. The results of the pilot implementation and evaluation of the project showed that the project was challenging for the students on the one hand, but motivating and beneficial on the other hand.
