Educational robotics is one of the most prosperous fields of study currently. Although expen-sive educational robotic kits are used in high schools to teach robotics. University students do not have the knowledge base on the matter yet. More often, low-cost printed modular robots are used. 3d printers are the emergent tool to do faster prototypes in a cheaper way. Also, Open Source technologies are the way to share information. In this paper, we have done a low-cost printed modular robotic platform to teach robotics. Furthermore, we have done several experi-ments on how to teach educational robotics. Lastly, we have proposed a statistical model to get results from the experiments.
