EdScratch vs Rocksi

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.

Rocksi is a browser-based simulator for programming a 3D virtual robot with block-based code. It is free, requires no registration, and runs in modern browsers such as Firefox, Chrome, and Safari without a download or installation. Listed robot models include Franka, Niryo NED, Sawyer, and Robotiq grippers. The maker says Rocksi was created with education in mind, for settings such as school classes, university lectures, workshops, and fairs; its stated learner level is mixed. Its software page names Blockly and JS-Interpreter among the programming libraries, as well as three.js, cannon-es, urdf-loaders, and xacro-parser among the 3D libraries. Supported platforms also include iPhone, iPad, iOS, Android, Linux, and Windows. The project is described as MIT-licensed in its source repository. Robokind Stiftung, based in Hannover, Germany, is identified as the responsible organization and privacy data controller. The privacy policy says server logs may contain browser and operating system details, pages visited, visit times, and IP addresses, normally deleted within seven days.
