Abstract

As robotics education evolves, there is a growing demand for effective tools that offer hands-on learning experiences while addressing the traditional challenges such as limited interactivity, high costs, and the need for sophisticated technical knowledge. This paper explores the integration of wireless controllers and Augmented Reality (AR) image tracking with the Dobot Magician Lite robotic platform to enhance robotics learning. The proposed solution utilizes MQTT (Message Queuing Telemetry Transport), a lightweight messaging protocol, to enable intuitive and user-friendly wireless control of the robot. By using AR image tracking, students may see and operate virtual overlays that are aligned with the actual robot, bridging the gap between theoretical understanding and practical application. This technique not only streamlines the control procedure, but it also creates an interesting and immersive learning environment, making robotics education more accessible to a larger range of people. Team Alpha (n=4) and Team Beta (n=4) conducted testing in Indonesia and found promising results: average response time was 160 ms and 165 ms, respectively; movement accuracy was 1.5 mm and 1.7 mm; AR display quality received scores of 8.8 and 8.6; and user satisfaction ratings were 9.0 and 8.9. Both teams reported great system adaptability and minimal issue frequency, with Team Beta mentioning minor performance difficulties including occasional latency.  These findings highlight the effectiveness and reliability of the proposed system, supporting its potential for broader application in robotics education.

Abstract

The lack of interest among students in studying art, particularly the traditional Indonesian art form of batik, poses a significant challenge for educational institutions. Despite its cultural significance, the education sector lacks effective strategies to introduce and enhance students' interest in batik within the art curriculum. Several consequences can arise if the education sector fails to implement strategic measures to address this issue promptly. This could lead to a gradual erosion of cultural heritage and a loss of artistic traditions passed down through generations, and students may miss out on valuable opportunities for self-expression and cultural exploration. This study addresses this issue by leveraging mixed reality and gamification in a batik creation application. This innovative approach not only enhances the pedagogy of art education but also aims to revive cultural interest. The study employs Software Testing and PIECES to evaluate user experiences, emphasizing user comfort and smooth interactions. By assessing the application with tools like Unity Profiler and Hololens 2 performance testing, the study ensures an optimal user experience, contributing to the broader goal of preserving Indonesia's cultural heritage through innovative and accessible educational solutions. The results fall within the range of 4.04 to 4.24, categorizing user satisfaction as "satisfied" and the application running at an optimal 60 frames per second (FPS). This implies that users responded positively to the application, indicating that implementing mixed reality technology in batik learning provides a satisfying experience.
