mBlock vs Open Roberta Lab

mBlock 5 is a free coding platform for robotics, STEM, and coding learning. It supports block-based coding and Python, with a one-click switch between the two. Users can create games and animations, then program Makeblock robots and other open-resource hardware. The platform includes AI and IoT features, with integrations described for Microsoft Cognitive Services and Google deep learning. Supported devices listed include CyberPi, mBot Neo/mBot2, mBot, mBot Ranger, Ultimate 2.0, mBot Mega, mTiny, Codey Rocky, and xLight. The Extension Builder allows third parties to develop device and sprite extensions. mBlock is available on Android, iOS, Linux, macOS, web, and Windows. The web version supports direct Bluetooth or serial connections, but not the Bluetooth dongle. The mBlock Python editor programs devices only for CyberPi, and its Upload mode uses MicroPython rather than third-party Python 3 libraries. The Extension Builder works only in Google Chrome.

Open Roberta Lab is a free online programming environment for learning with robots and microcontrollers. Its NEPO language uses graphical blocks assembled by drag and drop. The Lab supports hardware including Arduino boards, Calliope mini, LEGO Mindstorms EV3, micro:bit, NAO, LEGO SPIKE Prime and many other listed systems. Open Roberta Sim provides virtual robots for users without physical equipment. An integration also lets NEPO programs create and use artificial neural networks. The service runs in a standard browser on a PC, Mac or tablet without installation, and iOS and Android apps are listed. Programming works without an account; an account saves programs and settings, while sharing or gallery publication requires a verified email account. The site is hosted on Fraunhofer IAIS servers in Germany, with personal data kept within the EU. Visitor IP addresses are deleted from server logs after 30 days. The initiative targets children, young people, trainees and employees exploring STEM.
