The Zumo Shield is designed specifically to be a convenient interface between a Zumo chassis and an A-Star 32U4 Prime, Arduino Uno, or Arduino Leonardo. The shield mounts directly to the chassis, connecting to its battery terminals and motors, and the A-Star Prime or 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 a 3-axis accelerometer, compass, and gyroscope for sensing impacts and tracking orientation.
With the Zumo Shield and an Arduino (or compatible board like the A-Star Prime), the Zumo chassis becomes a low-profile, Arduino-controlled tracked robot that is less than 10 cm on each side (small enough to qualify for Mini-Sumo competitions). It works with a variety of micro metal gearmotors to allow for a customizable combination of torque and speed, and a stainless steel sumo blade is available for applications that involve pushing around other objects. Arduino libraries and sample sketches are available for quickly getting a Zumo robot up and running.
This is the v1.3 version of the Zumo Shield. It uses an LSM6DS33 accelerometer and gyro and an LIS3MDL magnetometer, replacing the LSM303D and L3GD20H sensors on the previous v1.2 revision. You can use the updated Zumo Shield Arduino library to help you write code that will work with the inertial sensors on any revision.
In addition, the power switch and pushbuttons on the v1.3 shield are surface-mount components instead of through-hole parts like those on the v1.2 version.
- Integrated DRV8835 dual motor drivers capable of delivering enough current for two high-power (HP) micro metal gearmotors. See the Zumo chassis product page for specific motor suggestions.
- Piezo buzzer for playing simple sounds and music. The buzzer is controlled by one of the Arduino’s PWM outputs, so the tones can be generated in the background without taking up a lot of processing power.
- Integrated LSM6DS33 3-axis accelerometer and gyro and LIS3MDL 3-axis magnetometer. These inertial sensors can be used for applications like sensing impacts to the Zumo and measuring its rotation.
- Optional user pushbutton on pin 12.
- 7.5 V boost regulator for powering the Arduino from the Zumo’s 4 AA batteries.
- Convenient access to Arduino I/O lines, the pin 13 user LED, and the Arduino reset line via the shield.
- General-purpose prototyping areas and an expansion area at the front for connecting additional sensors (it is easy to add a Zumo reflectance sensor array or up to five QTR sensors for edge detection or line following).
- Compatible with the Arduino Uno R3 and Arduino Leonardo, and can also be used with older Arduinos that have the same form factor, like the Duemilanove.
- An Arduino library and sample code make getting started easy.
- Detailed user’s guide with assembly instructions.
