Product description: Zumo 32u4 - minisumo robot with OLED and HP 100:1 motors - assembled Arduino compatible - Pololu 4993
Ready-made platform of a fighting educational robot. Pololu Zumo 32u4 platform based on ATmega32u4 microcontroller with Arduino bootloader uploaded. Zumo is programmed via microUSB port and Arduino IDE environment. The robot is equipped with two Pololu HP 100:1 motors characterized by a low speed of 310 rpm and high torque of 1.7 kg*cm. The Zumo 32u4 also features a small OLED display, line tracking sensors, ultrasonic distance sensors, accelerometer, compass and gyroscope. To start playing, just insert the batteries - four big st icks - and program the robot, connecting it to the computer via microUSB cable using Arduino IDE environment.
The main board of the Pololu Zumo fighting robot.Pololu Zumo 32u4 robot motherboard
The Pololu Zumo 32u4 robot platform is based on a motherboard with the ATmega32u4 chip, also used in Pololu A-Star boards. The Arduino bootloader embedded on the microcontroller allows programming the robot using a microUSB cable in the Arduino IDE environment. In addition to the built-in microcontroller, the Zumo platform is also equipped with: four ultrasonic distance sensors, a matrix of line tracking sensors, a dual motor controller with encoders, an OLED display, a buzzer, an accelerometer, a compass and a gyroscope.
