This combination deal contains most of the parts you need to build an Arduino-controlled Zumo robot. It consists of a Zumo Shield for Arduino, a Zumo chassis kit, and a Zumo blade. You will also need a pair of micro metal gearmotors, four AA batteries, and an Arduino to complete your Zumo robot (motors, batteries, and Arduino sold separately). This product is a kit; assembly (including soldering) is required.

New version available: This product is being replaced by the newer Zumo Robot Kit for Arduino, v1.2 (No Motors), which includes a gyroscope as well as a newer accelerometer and magnetometer. The only reason to get the old version is if you want identical units to ones you already have (e.g. in a class where several units are shared), and even then, you should still consider the newer version since it is a drop-in replacement except for a few small changes to the magnetometer and accelerometer code.

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.

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. The Zumo Shield works with both the Uno and the 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.
