The complexity of microcontroller learning that must combine theoretical concepts and real practices makes it difficult for many students to master the competencies of microcontroller control systems. In addition, it is difficult to achieve practical skills that students must master without a training kit that can interpret the application of microcontroller control systems. Thus, the purpose of this study is to examine the effectiveness of mobile robotic training kits to improve student learning achievement, practical skills, and problem-solving skills. This study used a mixed method with a sequential explanatory design, combining true-experimental research with semi-structured interviews. It involved 76 participants, divided into 38 experimental groups and 38 control groups selected at random. The results of this study show that the mobile robotic training kit is significantly effective in improving students’ learning achievement, practical skills, and problem-solving skills in the field of microcontroller control systems. This study provides empirical evidence of the importance of implementing a mobile robotics training kit in the learning process to improve students’ competencies and prepare them with competencies relevant to the needs of the world of work. © 2025 by the authors of this article.
