its not too complicated to build and does not take long to finish one of the Robots. the App is great and offers Dozen more cool builds. the App lets you build body parts step by setup and after setup is done you test with a little premade program, which motivates you to finish the complete model. nice video explanations and help system inside the app. latest updates also add basic machine learnin Heri · LEGO
