BluPants vs Sphero Edu

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.

Sphero Edu is a coding app for programming Sphero robots, with lessons and activities for learners. Depending on the app version, learners can use Draw, Blocks, JavaScript, or Python; a Drive mode connects to compatible robots over Bluetooth. The app includes hundreds of lessons, including standards-aligned activities. Educators can manage classes and assign work, and users can create programs to share with the community. Sphero Edu is free, with app and web access; robot programming requires a compatible Sphero robot. It runs on Android, iOS, macOS, Windows, and the web. Web robot connections use Web Bluetooth, which is listed as supported in Chrome and Edge, but not Safari, Firefox, or Opera. The web app supports BOLT+, BOLT, RVR/RVR+, and Mini, rather than every robot supported by native apps. Users can drive, program, and complete lessons without logging in or sharing personal information. Google Classroom roster syncing is read-only.
