Zumo 32U4 Robot Kit (Assembled with 100:1 HP Motors)

• User-programmable and customizable tracked robot
• Fully assembled with 100:1 motors
• Based on the Arduino-compatible ATmega32U4 MCU
• Software add-on is available that makes it easy to program the robot from the Arduino environment

The Zumo 32U4 Robot Kit (Assembled with 100:1 HP Motors) is a versatile tracked robot based on the Arduino-compatible ATmega32U4 MCU. It includes two 100:1 HP micro metal gearmotors along with integrated dual motor drivers, an LCD, quadrature encoders, line sensors, side and front proximity sensors for detecting objects, and a full IMU for detecting impacts and tracking orientation. The low-profile robot is less than 10 cm × 10 cm—small enough to qualify for Mini Sumo. No soldering or assembly is required; just add 4 AA batteries and a USB cable and your Zumo is ready for programming.

At the heart of the Zumo 32U4 is an Atmel ATmega32U4 AVR microcontroller. A software add-on is available that makes it easy to program the robot from the Arduino environment. A USB A to Micro-B cable (not included) is required for programming. For advanced users who want to customize or enhance their robots with additional peripherals, the robot’s power rails and microcontroller’s I/O lines can be accessed via 0.1″-spaced through-holes along the sides and front of the main board.

The Zumo 32U4 features two H-bridge motor drivers and a variety of integrated sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyro, and magnetometer), five downward-facing reflectance sensors for line-following or edge-detection, and front- and side-facing proximity sensors for obstacle detection and ranging. Three on-board pushbuttons offer a convenient interface for user input, and an LCD, buzzer, and indicator LEDs allow the robot to provide feedback.
