The Makeblock mBot2 Rover (Interactive Emo Robot) is an advanced STEM educational robotics kit designed for children aged 8 and up. It combines the powerful mBot2 coding robot with a Rover add-on pack, turning it into a treaded exploration vehicle and an interactive "Emo Robot" that can communicate its feelings through its screen.

Powered by the CyberPi microcontroller, the robot features a 1.44-inch full-color screen where kids can sketch, display, or generate custom emojis to bring their robot companion to life. Equipped with a robust drive system, heavy-duty tracks, and metal shock absorbers, the mBot2 Rover can conquer outdoor terrains and slopes up to 40°. It can be easily programmed using mBlock, facilitating a smooth transition from block-based coding (Scratch) to text-based Python.
