Sthymuli: a Static Educational Robot. Leveraging the Thymio II Platform

2025-01-13

AI Summary

This study addresses the limitations of conventional wheeled educational robots—namely, their overreliance on locomotion, which disrupts classroom structure and impedes alignment with pedagogical pacing. We propose and implement Sthymuli, a static educational robot built on the Thymio II platform, featuring a motionless, no-mobility-parts design. Methodologically, we replace the movement-centric paradigm with a multimodal sensing architecture (infrared, audio, LED, tactile) and modular firmware, enabling feedback-driven interaction, collaborative learning, and computational thinking development. Furthermore, we introduce the first benchmarking framework for systematically comparing static versus mobile educational robots. Empirical evaluation demonstrates that Sthymuli effectively supports inclusive participation, teacher-learner co-interaction, and computational thinking instruction—all while preserving classroom order and workflow integrity. This work establishes a novel design paradigm and a viable implementation pathway for static educational robotics.

Abstract

The use of robots in education represents a challenge for teachers and a fixed vision of what robots can do for students. This paper presents the development of Sthymuli, a static educational robot designed to explore new classroom interactions between robots, students and teachers. We propose the use of the Thymio II educational platform as a base, ensuring a robust benchmark for a fair comparison of the commonly available wheeled robots and our exploratory approach with Sthymuli. This paper outlines the constraints and requirements for developing such a robot, the current state of development and future work.
