Zumo 32U4 Robot (complex, with 75: 1 HP motors)

Description

A minisumo class robot from Pololu based on a tracked chassis. Dimensions (approx. 100 mm x 100 mm) and weight (approx. 300 g with batteries) allow the robot to be used as a minisumo platform in popular competitions for pupils and students organized around the world.

Zumo 32U4 is a robot based on ATmega32U4 MCU compatible with Arduino. It has two H-bridge motor controllers and a series 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 reflection sensors for line or edge detection, and proximity sensors forward and sideways for detecting obstacles and determining the distance from an obstacle. The three buttons offer a convenient user input interface, while the LCD display, buzzer and LEDs give feedback to the operator. The robot is equipped with two Pololu 75:1 HP motors with a metal gear.

The robot has a built-in microcontroller with an Arduino Leonardo compatible bootloader. As a result, the programming process of the robot does not require an additional programmer, and the controller is programmed via the USB port.

The robot has extensive support in the form of Arduino libraries for all the systems available on the board. It is also available as a set with a complex robot in a version with motors with a gear 50:1, 100:1 and as a kit for self-assembly.
