BluPants
What BluPants is
BluPants is a free, browser-based coding environment for programming robots. It brings several robotic platforms into one workspace, including BeagleBone, LEGO EV3, Raspberry Pi, and AlphaBot2-Pi. Learners can begin with visual blocks and move on to Python, making it suitable for a range of learner levels and for children who are not yet reading. Its curriculum library offers lessons that start with basic commands and build toward challenges involving computer science concepts. Activities cover moving a robot, picking up and dropping objects, transporting objects, and repetition loops. BluPants describes lessons using a real robot in person or remotely; one remote lab activity uses a distance sensor and repetition loops. The site says lessons are compatible with online classes and links activities to Hour of Code. For supported robot kits, it provides step-by-step build tutorials, with SD card images available for BeagleBone, LEGO EV3, and Raspberry Pi builds. BluPants runs in a web browser and supports both block-based and text coding, but it does not include a robot simulator.
