Here is another robot kit that teaches your kids the basics of coding. The Qdee robot kit is powered by micro:bit and can be configured in a variety of ways. It is also compatible with LEGO blocks. You get an extension board to attach lights, sensors, buzzers, and a whole lot more.
Qdee can be programmed using a graphical programming interface. Kids can read sensor data and play with code on their iOS/Android device.
