BluPants vs PictoBlox

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.

PictoBlox is educational software for learning graphical block-based coding and Python through projects in games, animations, IoT, robotics, AI and machine learning. Its AI tools include face detection and recognition, computer vision, natural language processing, object and human-pose detection, speech recognition and QR scanning. The machine-learning environment supports classification or regression models for image, object, hand-pose, pose, audio, text and number data. The Python editor includes a code visualizer, debugger, autocomplete, interactive REPL and inbuilt PIP package manager. In 3D and XR Studio, learners can make models and interactive AR or VR projects with blocks or Python, then export projects to Google Cardboard VR, Pico VR or Meta Quest. PictoBlox can program compatible hardware over USB or Bluetooth, including Arduino, Quarky, evive, LEGO and micro:bit devices. Junior Blocks offers activities for children ages 4–7. The free plan is for individual, non-commercial use; the product is proprietary, not open source.
