Product description: Zumo 32u4 - minisumo robot with OLED and HP 50:1 motors - complex, Arduino compatible - Pololu 4991
Complex educational fighting robot platform, based on ATmega32u4 microcontroller with Arduino bootloader uploaded, programmable via USB. The robot is equipped with two Pololu HP 50:1 motors featuring a high speed of 625 rpm but low torque of 1.1 kg*cm. The platform also has a small OLED screen, line tracking sensors, ultrasonic distance sensors, accelerometer, compass and gyroscope. To start playing, just insert the batteries - four big sticks - and program the robot by connecting it to the computer via a microUSB cable using the Arduino IDE environment.

The robot's main controller is based on the ATmega32u4 chip, also used in the Pololu A-Star board. Thanks to the Arduino bootloader loaded on the microcontroller, programming of the robot is done via a microUSB cable and Arduino IDE environment. In addition to the built-in microcontroller, the platform also features: four ultrasonic distance sensors, a matrix of line tracking sensors, a dual motor controller with encoders, OLED display, buzzer, accelerometer, compass and gyroscope.
Kit contents
