Zumo Robot for Arduino, v1.2 (Assembled with 75:1 HP Motors) by Pololu

Description

Integrated 75:1 HP micro metal gearmotors that offer a good blend of speed (up to 2 feet per second), power, and control. Mounted array of six IR reflectance sensors that allows the Zumo to detect contrasts in reflectivity directly beneath its blade, which can be used for following lines or detecting edges (e.g. the white outer area of a sumo ring or the edge of a table). Integrated DRV8835 dual motor drivers capable of delivering enough current for the Zumo’s two high-power gearmotors. Piezo buzzer for playing simple sounds and music. The buzzer is controlled by one of the Arduino’s PWM outputs, so tones can be generated in the background without taking up a lot of processing power.
