Semi-autonomous color line-following educational robots: Design and implementation

We describe an interactive game for children, employing semi-autonomous color line-following mobile robots. The design and implementation of the mobile robots is described in detail. Although the robots have intelligence that allows them to follow color lines, users interact with them and provide high-level commands such as what color line to follow after reaching a node, and the speed at which they should move. The paper describes the architecture of the game, focusing at the mechatronics aspects and the hardware and software implementation design choices made. It was observed that the game is more appropriate for children over seven years. To the best of the authors´ knowledge, this is the first interactive game of this kind at this scale in the world.
