If you have a motor raising and lowering, you need to put an interface on the screen to explain what is happening, and if the interface is interactive, we are hitting the core-level of robotics understanding that we originally were going over student’s heads with NXTs because the software-hardware-interaction was not immediate.Īn example program I created is called updownduck where a physical LEGO Duck is raised and lowered by clicking the words UP and DOWN on the screen. Directly plug in the LEGO WeDo USB to the computer with pre-loaded free Scratch drag-and-drop the robotics components will automatically appear in Scratch. LEGO Software is available for younger students, but Scratch programming has inherent drag-and-drop blocks that resemble MIT App Inventor interfaces for Android Phones that my advanced students have been using.
