Note: This product is a kit; assembly (including soldering) is required. Motors, batteries, and Arduino are sold separately. An assembled version is available that does not require any assembly or soldering and includes motors and a Zumo reflectance sensor array.

New inertial sensors! In September 2020, we started transitioning to shipping this kit with the v1.3 version of the Zumo Shield. The main difference is the new version replaces the shield’s inertial sensors with an LSM6DS33 accelerometer and gyro and an LIS3MDL magnetometer, as the LSM303D accelerometer and magnetometer used on the original revision has been discontinued. You can use our updated Zumo Shield Arduino library to help you write code that will work with the inertial sensors on either revision. In addition, the power switch and pushbuttons on the v1.3 shield have been changed to be surface-mount parts. For more information, see the user’s guide.

All units shipping now from Pololu have the newer v1.3 shield. If you require units with the previous v1.2 version, please contact us before you place your order.

Zumo Robot for Arduino, v1.2.

Zumo chassis being assembled with two Micro Metal Gearmotor.

Required Accessories (not included)

• Two micro metal gearmotors. These gearmotors are available in several power options and a wide variety of gear ratios, allowing for a customizable combination of torque and speed. The Zumo Shield can deliver enough power for all of the micro metal gearmotors we carry, including the high-power (HP) versions. Note that some gear ratios are better suited for the Zumo than others; please see the Zumo chassis kit product page for specific motor suggestions.
• Four AA batteries. The Zumo chassis works with both alkaline and NiMH batteries, though we recommend rechargeable NiMH cells.
• An Arduino or compatible control board. The Zumo Shield works with the A-Star 32U4 Prime, Arduino Uno and Arduino 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. (Other Arduino-compatible controllers might work with the Zumo robot, but support for them will be limited and they might require modification; for example, one customer got his Zumo robot working with the Freescale FRDM-KL25Z board.)

Optional Accessories

• Zumo reflectance sensor array. This sensor bar mounts along the front edge of the Zumo shield and allows the Zumo to detect features on the ground in front of it, such as lines for following or edges for avoiding (such as the rim of a sumo ring or the edge of a table). It is designed specifically for use with the Zumo shield.
• iMAX-B6AC battery charger for charging the Zumo’s battery’s through the Zumo Shield’s 2-pin charge port. Note that you only need a battery charger if you plan on powering the Zumo with rechargeable cells, and that charger should be capable of charging 4 NiMH cells in series. Alternatively, since the Zumo just uses ordinary AA batteries, you can use AA chargers (into which you stick the individual cells) available at most general electronics stores.
• Optical rangefinders for obstacle/opponent detection.
• Connectors (headers, jumper wires, etc) for adding more sensors.
• Replacement sprockets in red or white. The Zumo robot for Arduino includes the black sprockets shown in the left picture below, but other colors can be purchased separately if you want to add a bit of personalization to your robot. The following pictures show the newer Zumo 32U4 Robot, which is based on the same Zumo chassis and therefore uses the same sprockets:

Comparison with the Zumo 32U4 robot

The newer Zumo 32U4 is another robot based on the Zumo chassis. It is a more highly integrated robot than the Zumo robot for Arduino, with enhancements that include a built-in Arduino-compatible ATmega32U4 microcontroller (the same one used in the Arduino Leonardo and A-Star 32U4 boards), an LCD, encoders for closed-loop motor control, and proximity sensors for obstacle detection. The Zumo 32U4 main board effectively combines the functions of the Zumo Shield and the separate Arduino controller into a single, compact board that is just as easy to program as a standard Arduino or A-Star thanks to its USB interface and preloaded Arduino-compatible bootloader.

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.
