EdScratch vs ROBO Pro Coding

EdScratch is a free, browser-based block programming environment for Edison robots. Its vertical drag-and-drop language is based on Scratch and is described as suitable for students aged 10 and up, including those new to coding. It has versions for Edison V2 and V3, with blocks for driving, LEDs, sound, data, events, control, sensing, operators, and comments. Programs can control robot inputs, manipulate data, and use variables. A built-in bug box checks programs and displays warnings. Users can save programs to a computer and load saved EdScratch files into the online app. Edison V3 can receive programs by USB from a computer or by optical flashing from an iPad; V1 and V2 use the EdComm cable. A free lesson set offers 98 student activity options across six units, along with a teacher’s guide. EdScratch runs online on the web, Windows, macOS, iPadOS, and Android, and requires an internet connection. The interface is in English, while lesson resources are available in multiple languages.

ROBO Pro Coding is a free programming environment for fischertechnik toys and schools. Learners can program graphically or with Python, and choose beginner, advanced or expert learning levels. The app provides example programs and supports the TXT 4.0 controller, as well as RX and BT Smart controllers according to its release notes. Programs can be kept locally or in the cloud, where they can be versioned and shared. An interface test helps users check actuators and sensors. The TXT 4.0 connects to computers and mobile devices through Wi-Fi, Bluetooth and USB. Published documentation includes blocks for voice control and Cloud/MQTT communication. The manufacturer describes Python 3 support with TXT 4.0 and links to app documentation and downloads for Windows, macOS, Linux, iOS and Android. The older TXT controller is not supported by this app and uses ROBO Pro for Windows instead. The manufacturer also offers customer support for questions and problems.
