This is Pololu 3pi+ 32U4 OLED Robot Kit with 30:1 MP Motors (Standard Edition Kit).

This is a 3pi+ 32U4 OLED Robot unassembled Kit with 30:1 MP Motors. The 3pi+ 32U4 is a versatile, high-performance, user-programmable robot that measures just 9.7 cm (3.8) in diameter. At its heart is an ATmega32U4 AVR microcontroller from Microchip (formerly Atmel), and like our A-Star 32U4 programmable controllers, the 3pi+ 32U4 features a USB interface and ships preloaded with an Arduino-compatible bootloader, so all you need to program it is a USB A to Micro-B cable (not included). A software add-on is available that makes it easy to program the robot from the Arduino environment, and we have Arduino libraries and example sketches to help get you started.

The 3pi+ 32U4 OLED Robot Kit with 30:1 MP Motors which has 3pi+features two H-bridge motor drivers and a variety of integrated sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyro, and magnetometer), five downward-facing reflectance sensors for line-following or edge-detection, and left and right bump sensors along the front face of the robot. Three onboard pushbuttons offer a convenient interface for user input, and an LCD, buzzer, and indicator LEDs allow the robot to provide feedback.

Features:

1. Two H-bridge motor drivers and USB interface with ships
2. A unique power system that runs the motors at a constant 8 V independent of the battery charge level
3. ATmega32U4 microcontroller with Arduino-compatible bootloader can be programmed directly through a USB connection
4. Two bump sensors on the front
5. Bottom-loading battery holders keep batteries accessible even if additional levels are added
