In their own words
Rocksi
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. The homepage provides an email address for updates and feedback.
SaySpark
SaySpark is a robotics education platform for children, available through the web, Windows 10 or 11, and an Android companion. Children speak requests to the Spark AI tutor, hear its plan in plain language, and ask follow-up questions. The Spark Mini robot adds a microphone, speaker, camera, ultrasonic sensor, and motion sensor for spoken interaction, vision, distance measurement, and turns. It can tackle unfamiliar mazes, explain decisions at junctions, and use its camera to confirm an exit. A browser simulator provides challenges, a sandbox, world builder, and WASD controls, with five prompts available without an account. Lessons are arranged by age band with XP, badges, and a visible learning path. Classroom activities use class codes; teachers receive rosters, leaderboards, and assessments. The Windows download includes more than 20 guided challenges across five domains. Early access is free, with every feature unlocked; Spark Mini is separate hardware.
