The KitiBot is a fun full-metal tracked robot kit for the BBC micro:bit (not included). Using the micro:bit as the brains of the robot along with the chassis, controller board (with LEDs and Buzzer!), tracks, sensors and accessories provided in this kit, you can create an awesome micro:bit robot!

Learn how to code with the micro:bit whilst building a cool project! The KitiBot is coded using the graphical Microsoft MakeCode editor which is a block-based coding environment, making it easy to teach the concepts of programming without having to worry about heavy coding!

The KitiBot can be controlled via code, a smartphone app via Bluetooth or via a 2.4G wireless gamepad (not included). Using the included parts, users can make their KitiBot follow lines, detect and avoid objects, follow commands, run via remote control and even patrol with set directions! Check out the Kitty head with ultrasonic sensor - it's connected to a servo to move the head to inspect an area!

The KitiBot has power protection built in to keep users safe. The controller board uses a power management chip for both battery charging and boosting. There's also battery protection onboard, securing against reverse polarity, over-charging, discharging, over-current and short-circuits.

Note: This kit requires a micro:bit and a rechargeable 18650 Lithium battery which are not included.
