The new generation of educational robots, equipped with a controller, not only takes the lead in using touch screens, but also has a significant overall optimization compared to the traditional educational robot's controller. For educational robots, it is a "epochal" change. Touch screen is currently the simplest, most convenient and natural way of man-machine interaction. It has fast response speed, exceptionally convenient program operation, and clear command execution presentation mode, which is very suitable for young children to learn introductory studies and also facilitate adolescents to carry out more difficult explorations. At the same time, the touch screen is also rugged and saves space.
