Zumo Shield for Arduino, v1.2 Zumo Shield for Arduino, v1.2, with included through-hole components installed. Overview The Zumo Shield is designed specifically to be a convenient interface between a Zumo chassis and an Arduino Uno or Leonardo. The shield mounts directly to the chassis, connecting to its battery terminals and motors, and the Arduino plugs into the shields 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. The only differences between this v1.2 shield and the previous version are the addition of a 3-axis gyro and an upgrade of the accelerometer/magnetometer module. With the Zumo Shield and an Arduino, 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. Zumo robot assembled with a Zumo Shield and Arduino Uno, back view. Assembled Zumo robot with a Zumo Shield, Arduino Uno, and Zumo blade. This shield is also available as part of our Zumo Robot kit for Arduino, which bundles it with a Zumo chassis and Zumo blade, and in our Zumo Robot for Arduino, which is preassembled with 75:1 HPmicro metal gearmotors and a Zumo reflectance sensor array. Features 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 Arduinos PWM outputs, so the tones can be generated in the background without taking up a lot of processing power. Integrated LSM303D 3-axis accelerometer and 3-axis magnetometer that can be used to detect impacts. The compass gets a lot of interference from the motors, batteries, PCB, and its surroundings, so it is not generally useful for precision navigation, but we have found that with proper calibration, it can be used for rough orientation measuring in many environments. This part is an upgrade over the LSM303DLHC accelerometer/magnetometer IC included on previous versions of the Zumo shield for Arduino. Integrated L3GD20H 3-axis gyroscope that can be used to track rotation. This is new on the v1.2 version of the Zumo shield previous versions did not include a gyro. With this sensor and the LSM303D mentioned above, the shield effectively has a built-in MinIMU-9 v3 IMU module that can optionally be used to make a attitude and heading reference system (AHRS) so that your robot can its orientation. Optional user pushbutton on pin 12. 7.5 V boost regulator for powering the Arduino from the Zumos 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. Arduino libraries and sample code make getting started easy. Detailed users guide with assembly instructions.
