It is difficult to motivate learners to learn abstract Computer Science topics (e.g., data structures, algorithms and programming) with the adequate level of engagement. We present the process of constructing a LEGO robot, called the DRAWBOT (drawing robot), which enables to create the e-learning environment to demonstrate visually the solution of graph-based Computer Science tasks through teaching programming. Our research has confirmed the importance of using robot-based environments for teaching that was known so far in the literature on e-learning. We have extended the known approaches: a) by providing technical characteristics for the process to create the e-learning environment for the real setting; b) by smoothly integrating different phases of the process and considering it into entirety to support the constructivist learning model.DOI: http://dx.doi.org/10.5755/j01.eee.18.9.2825
