Pololu 3pi+2040 Robot Kit with 75:1 LP Motor (Turtle Edition Kit)

Powered by Raspberry Pi RP2040 microcontroller

Programming can be done using C++, Arduino, or Python

Equipped with multiple integrated sensors

Featuring a unique power system that enables constant motor speed

Pololu 3pi+2040 Robot Kit (with 75:1 LP motor) (Turtle Edition Kit) is a compact high-performance mobile platform that uses Raspberry Pi RP2040 MCU. This kit provides all the components needed to build the Turtle version, including a pair of 75:1 LP 6V miniature metal gear motors. The 3pi+is equipped with multiple features, such as a dual orthogonal encoder for precise speed or position control, line sensors, front collision sensors, integrated IMU (3-axis accelerometer, magnetometer, and gyroscope), six RGB LEDs, and a graphic OLED display screen.

3pi+2040 is a multifunctional, high-performance, user programmable robot with a diameter of only 9.7 centimeters (3.8 inches). It is driven by the Raspberry Pi RP2040 microcontroller, a 32-bit dual core Arm Cortex-M0+processor with a running frequency of 125 MHz that can be programmed using C++, Arduino, or Python. 3pi+2040 is equipped with 16 MB (128 Mbit) flash memory and comes pre installed with a MicroPython interpreter. For those who wish to customize or enhance robots with additional peripheral devices, the robot's power rail, power system controls, and microcontroller I/O lines can be accessed through several 0.1 inch pitch expansion ports

The 3pi+2040 is equipped with two H-bridge motor drivers and various integrated sensors, including a pair of orthogonal encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyroscope, and magnetometer), five downward reflection sensors for line tracking or edge detection, and left and right collision sensors along the front of the robot. The robot also includes three onboard buttons for user input, a 128x64 graphic OLED display, a buzzer, and six RGB LEDs for providing feedback.

This robot has a unique power system that can maintain the motor at a constant 8V voltage regardless of the battery level, ensuring that the motor speed does not fluctuate with the battery voltage.

This kit is designed to build the Turtle Edition 3pi+2040 robot, with a maximum speed of approximately 0.4 meters per second, making it ideal for applications that require slow speed control, such as coordinated swarm robots and robot beginner courses. Assembly is required, including welding.
