Robots are an ideal educational tool for a hands-on introduction to technology. By designing, constructing, programming and testing mobile robots, children learn the basic concepts of today’s technical systems. In a playful approach, they learn to handle sensors, motors, programs and a graphical software development environment. These are the main technical topics of Roberta courses. In addition, they learn that constructing technical systems is a creative process that is not easy but strengthens their self-confidence in their own technical skills.
