The Zumo 32U4 robot is a complete, versatile robot controlled by an Arduino-compatible ATmega32U4 microcontroller. When assembled, the low-profile tracked robot measures less than 10 cm on each side, making it suitable for Mini-Sumo competitions.

At the heart of the Zumo 32U4 is an integrated ATmega32U4 AVR microcontroller from Atmel, along with dual H-bridge drivers that power the robot’s motors. The robot also features a variety of sensors, including quadrature encoders and inertial sensors (accelerometer and gyro) on the main board, along with reflectance and proximity sensors on the front sensor array. On-board pushbuttons offer a convenient interface for user input, and an LCD, buzzer, and indicator LEDs allow the robot to provide feedback.

Like our A-Star 32U4 programmable controllers, the Zumo 32U4 features a USB interface and ships preloaded with an Arduino-compatible bootloader. We provide a software add-on that makes it easy to program the Zumo 32U4 from the Arduino environment, as well as a set of Arduino libraries to help interface with its on-board hardware.

The latest revision of the Zumo 32U4 main board is version 1.1, which has an LSM6DS33 accelerometer and gyro and an LIS3MDL magnetometer. The information in this user’s guide also applies to the original Zumo 32U4 Main Board v1.0, which had an LSM303D accelerometer and magnetometer and L3GD20H gyro.

Comparison with the Zumo robot kit for Arduino (with Zumo Shield)

Our older Zumo robot for Arduino, built with a Zumo Shield, is another Arduino-compatible robotic platform based on the Zumo chassis. The Zumo Shield is designed for a board with a standard Arduino form factor, like an Arduino Uno, Arduino Leonardo, or A-Star 32U4 Prime, to plug into it and act as its controller.

By contrast, the Zumo 32U4 includes an on-board ATmega32U4 microcontroller (the same one used in the Leonardo and A-Star 32U4 boards), combining the functions of the Zumo Shield and the separate Arduino controller into a single board and enabling the resulting robot to be even more compact. However, it remains just as easy to program as a standard Arduino, thanks to its USB interface and preloaded Arduino-compatible bootloader. The Zumo 32U4 also adds many features that are not found on the Zumo Shield, including encoders, an LCD, and proximity detection.

Some of the pin mappings and software libraries differ between the Zumo 32U4 and Zumo robot for Arduino, so programs written for one robot generally need to be modified to work on the other.
