The Zumo 2040 robot is a versatile, high-performance, user-programmable robot. When assembled, the low-profile tracked robot measures less than 10 cm on each side, making it suitable for Mini-Sumo competitions. At its heart is a Raspberry Pi RP2040 microcontroller (like the one on the Raspberry Pi Pico), a 32-bit dual-core Arm Cortex-M0+ processor running at 125 MHz, which can be programmed with C, C++, Arduino, or Python. The Zumo 2040 has 16 MB (128 Mbit) of flash memory that ships preloaded with a MicroPython interpreter, so you can get started right away by plugging into its USB-C port and editing the included example Python programs.

The Zumo 2040 also features two H-bridge motor drivers and a variety of sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyro, and magnetometer), reflectance sensors for line following, and proximity sensors for detecting nearby objects. On-board pushbuttons offer a convenient interface for user input, and a 128×64 graphical OLED display, buzzer, and six RGB LEDs allow the robot to provide feedback. For advanced users who want to customize or enhance their robots with additional peripherals, the robot’s power rails, power system controls, and microcontroller’s I/O lines can be accessed via several 0.1″-pitch expansion ports.
