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

KitiBot X Micro:bit Tracked Robot

When KitiBot meets micro: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.

Note: the 2.4G gamepad is NOT included in the price, besides, totally two micro:bit are required for 2.4G RF remote control.

Controller Introduction

The BBC micro:bit is an open development board that allows you to run code on it and have access to all of the hardware.

You can use your BBC micro:bit for all sorts of cool creations, from robots to video games – the possibilities are endless.
