Build your fischertechnik® TXT 4.0 Controller model and bring it to life with the ROBO Pro Coding App.
The software ROBO Pro Coding from fischertechnik® offers in its multilingual environment, in addition to the possibility of graphical programming, text-based programming via Python. Users can choose from beginner, advanced and expert learning levels to work at the appropriate level of difficulty. Program examples are available. Self- created programs can be stored locally on the device and online in the cloud. This allows versioning and sharing of created programs in the cloud storage between users. Actuators and sensors can be tested quickly via the interface test.
