Zumo 32U4 OLED Robot Kit - a kit for building a minisumo robot (without motors, for assembly)

Description

A set for building 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 and controller) allow the robot to be used as a minisumo platform in popular competitions for pupils and students organized around the world.

The robot requires two DC Micro Pololu motors to drive the tracks. Zumo 32U4 has two motor controllers with an H bridge and a number of integrated sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyroscope and magnetometer), five reflection sensors for detecting lines or edges, and proximity sensors directed forward and side to detect obstacles and determine the distance. Three on-board buttons offer a convenient user input interface, while the OLED, buzzer and LEDs signal the robot feedback.

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 systems available on the board. It is also available in a version with motors as a set with a complex robot in a version with 50:1, 75:1 and 100:1 gear motors.
