Code

The software behind the class lives in a few GitHub repositories. Students mostly use the first one; the rest are the pieces it is built on and the tools the instructor uses to flash and manage the robots.

For students

nezha-robot-template

https://github.com/League-Microbit/nezha-robot-template

The project you start from. It is a MakeCode project, so you can open it in the MakeCode editor or in VS Code, and it already includes the DiffDrive extension and a few example programs (drive in a circle or a square, calibrate the wheels, calibrate turning). Each release on its Releases page is a ready-to-flash hex of the calibration program.

pxt-nezha-diffdrive

https://github.com/League-Robotics/pxt-nezha-diffdrive

The DiffDrive extension: the code that drives the Nezha board’s motors in a closed loop, so move 50 cm means 50 cm and turn 90° means 90°. It also provides the radio and Wi-Fi link the robot console talks to. Add it to your own MakeCode project as the extension League-Microbit/pxt-diff-drive, which is generated from this repository.

Remote-Joystick-Student

https://github.com/League-Microbit/Remote-Joystick-Student

The program for the joystick:bit remote. The robot console installs it on a joystick for you; this is its source, written so a student can read and change it.

Tools

robot-console

https://github.com/League-Robotics/robot-console

The console that finds robots over USB, radio and Wi-Fi, flashes firmware, runs the calibration wizards and drives a robot from the browser.

microbit-radio-relay

https://github.com/League-Robotics/microbit-radio-relay

The firmware for the radio bridge micro:bits that let the console reach a robot over the micro:bit radio.
