Roberta Lab
Welcome to
Open Roberta Lab
Learn to code robots with drag-and-drop blocks! 🚀
Program real robots OR use the built-in simulator!
Open Roberta Lab is a FREE cloud-based programming environment created by the Fraunhofer Institute in Germany!
It uses NEPO (a visual block-based language) that makes programming robots as easy as playing with LEGO blocks! 🧩
You can program 9+ different robot systems including LEGO MINDSTORMS, micro:bit, Calliope, mBot, Arduino, and more - all from your web browser!
🎯 Perfect For:
- ✅ Beginners - No coding experience needed!
- ✅ Classrooms - Used by thousands of schools worldwide
- ✅ Home Learning - Free and accessible anywhere
- ✅ All Ages - From 8 years old to adults!
