The Pololu 3pi+ 32U4 OLED robot is a complete, high-performance mobile platform based on the Arduino-compatible ATmega32U4 MCU. Its many features include dual quadrature encoders for closed-loop speed or position control, line sensors, front bump sensors, a full IMU (3-axis accelerometer, magnetometer, and gyro), and a graphical OLED display, all packed into a robot that fits in the palm of your hand. This Turtle Edition version is assembled with 75:1 LP 6V Micro Metal Gearmotors, which allow for longer battery life than the other editions. The maximum robot speed is approximately 0.4 m/s, making it well suited for applications where slow, controlled speed is important, such as coordinated swarm robots and introductory robotics courses.
The 3pi+ (or 3??+) 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 on-board pushbuttons offer a convenient interface for user input, and a 128x64 graphical OLED display, buzzer, and indicator LEDs allow the robot to provide feedback.
The robot also features a unique power system that runs the motors at a constant 8 V independent of the battery charge level, so the speed of the motors does not vary with the battery voltage.
