Front End Web Development Techdegree Graduate 84,738 PointsThe problem is the override init() method in the Robot class. Just get rid of that method and everything works. (I think somehow you were under the misconception that the robots should be initialized with a different point of origin, but this is not the case. Since that means it will have different coordinates after using the move function than the challenge is expecting, it doesn't pass)
