Product description: Zumo 32u4 - minisumo robot with OLED and HP 75:1 motors - assembled Arduino compatible - Pololu 4992
Assembled fighting educational robot, based on ATmega32u4 microcontroller with Arduino bootloader uploaded. Zumo is programmed via microUSB port and Arduino IDE environment. The platform is equipped with two Pololu HP 75:1 motors with an average speed of 400 rpm and an average torque of 1.3 kg*cm. The platform also features 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 main board of the Pololu Zumo fighting robot.Pololu Zumo 32u4 robot motherboard
The Pololu Zumo 32u4 robot is based on a motherboard with the ATmega32u4 microcontroller, also used in the Pololu A-Star boards. Arduino bootloader provides programming of the robot using microUSB cable and Arduino IDE environment. Apart from the built-in microcontroller, the platform is also equipped with: four ultrasonic distance sensors, line tracking sensor array, two motor controllers with encoders, OLED display, buzzer, accelerometer, compass and gyroscope.
