BluPants vs FinchBlox

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.

FinchBlox is BirdBrain Technologies’ block-based coding app for programming the Finch Robot 2.0. Its three levels build from sequencing the robot’s motors, lights, and buzzer to using parameters, sensors, loops, and concurrent sequences. Students can change code while it runs and remain connected to the robot. The app is free, but connecting the Finch requires a micro:bit with a specific Bluetooth .hex file, placed there using a computer with a USB port. FinchBlox is listed for Windows, Mac, Chrome/Chromebook, iOS, Android, and Kindle Fire. BirdBrain provides tutorials, block descriptions, classroom activities, and a teacher video course; activities include math, mazes, drawing, dance, and stories. The maker says its software is designed for children under 13, requests only permissions needed to function, and does not transmit personal information to BirdBrain. Bluetooth permission is required, and Android also requires location permission for Bluetooth.
