As a open source project, we need funds to maintain the project. One way is to charge users to access and register their robots in our platform. Doint thay you also have access to the community, so you can post questions, see other robots and participate of official Decabot competitions!
Yes! The Decabot directory can be used as your repository of personal robots. But non-decabot robots cannot score on competitions (so can’t show on DecaBoards).
