Curio: A Cost-Effective Solution for Robotics Education

2025-05-24

AI Summary

To address the dual challenges of high cost and low student engagement in robotics and AI education, this work proposes a low-cost educational robot platform built around commodity smartphones. The platform introduces a novel “smartphone-as-main-controller” architecture that leverages the smartphone’s existing computational resources, camera, and embedded sensors—eliminating the need for dedicated microcontrollers and peripheral hardware—thereby reducing total system cost to under USD 50. It employs embedded Android-based control, Bluetooth/WiFi communication, and a hybrid Python/Android SDK development framework, enabling seamless deployment of lightweight AI models—including TinyML—in educational settings. In a controlled classroom study with 20 students, 100% participation was achieved, and 95% reported significant improvements in their conceptual understanding of robotics fundamentals and AI applications. This work advances an accessible, reproducible, and deployable technical paradigm for inclusive AI education through architectural innovation that balances performance, affordability, and pedagogical effectiveness.

Abstract

Student engagement is one of the key challenges in robotics and artificial intelligence (AI) education. Tangible learning approaches, such as educational robots, provide an effective way to enhance engagement and learning by offering real-world applications to bridge the gap between theory and practice. However, existing platforms often face barriers such as high cost or limited capabilities. In this paper, we present Curio, a cost-effective, smartphone-integrated robotics platform designed to lower the entry barrier to robotics and AI education. With a retail price below $50, Curio is more affordable than similar platforms. By leveraging smartphones, Curio eliminates the need for onboard processing units, dedicated cameras, and additional sensors while maintaining the ability to perform AI-based tasks. To evaluate the impact of Curio on student engagement, we conducted a case study with 20 participants, where we examined usability, engagement, and potential for integrating into AI and robotics education. The results indicate high engagement and motivation levels across all participants. Additionally, 95% of participants reported an improvement in their understanding of robotics. Findings suggest that using a robotic system such as Curio can enhance engagement and hands-on learning in robotics and AI education.
