BluPants vs EdScratch

BluPants is a free, web-based coding environment for programming robots. It is designed for children of all ages, including pre-readers, and supports block-based visual programming that can progress to Python. One environment supports BeagleBone, LEGO EV3, Raspberry Pi, and AlphaBot2-Pi, with robot-building tutorials and SD card images listed for several builds. Lessons move from basic commands to more complex computer-science challenges. Activities include moving a robot, picking up or dropping objects, transporting items, and using repetition loops. BluPants describes learning with a real robot in person or remotely, including a remote lesson using a distance sensor and loops. Lessons are compatible with online classes, and activities are linked to Hour of Code. The curriculum library runs in a browser, but there is no robot simulator.

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.
