Abstract
This chapter presents the design and development of an open-source, low-cost robot for K12 students, suitable for use in educational robotics and science, technology, engineering, mathematics (STEM). The development of DuΒot is a continuation of previous research and robot's innovation is based on three axes: (a) its specifications came from the 1st cycle of action research; (b) robot's visual programming language is integrated into the robot, taking advantage of the fact that it can be programmed from any device (smartphone, tablet, PC) with an internet connection and without the need to install any software or app; (c) is low-cost with no “exotic” parts robot than anyone can build with less than 50€. Furthermore, the robot's initial evaluation is presented -from distance due to emergency restrictions of Covid-19 is presented by the University of Crete, Department of Preschool Education's students.
