How do we prepare the next generation for a world with artificial intelligence? BotsUp is an online game that allows children to intuitively become acquainted with working with AI. In the game, the players train robots with self-learning algorithms to perform tasks, to get an understanding of the strengths and weaknesses of this technology. The trained robots are shared with other players, showing the importance of open knowledge exchange. The project is made possible by the SIDN Fund, an independent foundation established by SIDN, the foundation for internet domain registration in the Netherlands. Version 0.3 (beta) of the game is currently live! Check it out at botsup.org.
