3pi+ 32U4 Robot - Standard Edition (30:1 MP Motors), Assembled
The Pololu 3pi+ 32U4 robot is a complete, high-performance mobile platform based on the Arduino-compatible ATmega32U4 MCU.
This Standard Edition version is assembled with 30:1 MP 6V Micro Metal Gearmotors, which offer a good combination of speed and controllability.
- just 9.7cm (3.8") in diameter
Its many features include dual quadrature encoders for closed-loop speed or position control, line sensors, front bump sensors, and a full IMU (3-axis accelerometer, magnetometer, and gyro), all packed into a robot that fits in the palm of your hand.
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).
The 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 on-board pushbuttons offer a convenient interface for user input, and an LCD, 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.
The 3pi+ 32U4 robot is available as a kit or fully assembled with three different motor options:
|3pi+ 32U4 Version||Products||Micro Metal Gearmotor||Top Speed||Comments|
