Build your fischertechnik® BT Smart Controller model and bring it to life with the ROBO Pro Smart App. The App’s graphical user interface is intuitive and icon-based. The icons are well known from e.g. the desktop version ROBO Pro and established for many years now. Drag-and-drop the icons, link them and run your code on the model. The use of iPads is preferred, but it works fine with iPhone's smaller displays.
