KitiBot Starter Tracked Robot Building Kit Based on BBC micro:bit (optional)

WhenKitiBotmeetsmicro:bit, when kids meet programming, the mysterious robotics becomes simple, each interesting idea will come true. By using the graphical programming software, learning programming, and exploring robotics would be as easy as building blocks.

This KitiBot tracked robot kit uses the BBC micro:bit as the host controller, combined with several functional modules, it is easy for the kids to experience robotic tricks such as: line tracking, obstacle avoiding, ultrasonic ranging, servo operation, Bluetooth remote control, etc.
