Mai-Z the MouseBot for BBC micro:bit

The Kitronik Mai-Z Educational Robot for BBC micro:bit brings coding to life for ages 8–14 with sensors, ZIP LEDs, speaker, USB-C charging, pen holder, and scoop. Supports MakeCode, Screen-Free Programming Pack, and CreateAI for gesture and AI-driven control.

Designed for hands-on learning, the Kitronik Mai-Z is a versatile educational robot built for the BBC micro:bit. Whether you're diving into coding with MakeCode’s block-based editor or exploring a world beyond monitor screens with our exclusive Screen-Free Programming add-on pack, Mai-Z makes STEM learning intuitive and fun. It’s even fully compatible with MakeCode CreateAI, allowing for gesture-based control and AI-powered coding right out of the box. Aligned with UK and US curricula, Mai-Z empowers both learners and teachers to master core computing concepts through interactive, project-based activities. Mai-Z has an impressive array of features, and each feature provides a new and exciting learning opportunity. Features include: Line following sensors, distance sensors, edge detecting sensors, 4 x programmable ZIP LEDs, a pen holder, scoop, button holes for micro:bit A/B button access, BBC micro:bit edge connector, rechargeable LiPo battery (no additional batteries required), speaker, USB-C charging port (cable included), on/off switch, and status LED.

Make full use of your micro:bit’s built-in tech. From accelerometer-based steering to compass-guided driving, Mai-Z makes robotics interactive and exciting. You can even control the Mousebot with gestures via MakeCode CreateAI. The motors driving Mai-Z's wheels are specifically designed for steady straight-line driving, which makes things such as line following and obstacle avoidance a smooth experience. Mai-Z is a feature-rich, robot Mouse buggy designed to make coding and robotics accessible, hands-on, and engaging for students aged 8–14. Developed for use with the BBC micro:bit, Mai-Z supports both MakeCode block-based programming and screen-free coding via our innovative Screen-Free Programming Pack, perfect for flexible learning environments. Whether you’re teaching in a classroom, running a STEM club, or looking for inclusive, progressive tech tools, Mai-Z offers a low-barrier of entry into computing and robotics, with room to grow into more complex challenges, including AI integration via MakeCode CreateAI. Power: Mai-Z features a Standard USB-C Charging Port. Mai-Z will charge regardless of the status of the power switch, and can be safely used whilst it is being charged. The charger must be capable of providing 5V, at least 1A over a USB-C Connection. micro:bit not included
