The Zumo Shield provides a convenient interface between our Zumo chassis and an Arduino Uno or Leonardo (it is not compatible with the Arduino Mega or Due, but it can be used with older Arduinos that have the same form factor as the Uno, such as the Duemilanove). The shield mounts directly to the chassis, connecting to its battery terminals and motors, and the Arduino plugs into the shield’s male header pins, face down. The shield provides all the electronics necessary to power the motors and includes some additional fun components for making a more interesting robot, such as a buzzer for making sounds and inertial sensors including an accelerometer and gyro.

A Zumo chassis, Zumo Shield, and Arduino can be combined to become a low-profile, Arduino-controlled tracked robot that is less than 10 cm on each side (small enough to qualify for Mini-Sumo competitions).

The latest revision of the Zumo Shield is version 1.2. This version adds an L3GD20H 3-axis gyroscope and upgrades the accelerometer and magnetometer chip to the newer LSM303D. It is available by itself, as part of a kit, or in a complete robot:

The information in this user’s guide also applies to the original Zumo Shield, which did not have a gyro and featured an LSM303DLHC accelerometer and magnetometer:
