Zumo 32U4 Robot Kit (Assembled with 75:1 HP Motors)

• Fully assembled with motors
• Versatile tracked robot based on the Arduino-compatible ATmega32U4 MCU
• Includes two 75:1 HP micro metal gearmotors along with integrated dual motor drivers
• LCD, quadrature encoders, line sensors, side and front proximity sensors for detecting objects

The Zumo 32U4 Robot Kit (Assembled with 75:1 HP Motors) is a highly integrated, user-programmable and customizable tracked robot. It measures less than 10 cm on each side and weighs approximately 275 g with batteries (170 g without), so it is both small enough and light enough to qualify for Mini-Sumo competitions, but its versatility makes it capable of much more than just robot sumo battles.

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.
