The Pololu 3pi+ 2040 Robot - Turtle Edition (75:1 LP Motors), Assembled is a compact, high-performance mobile platform that is powered by the Raspberry Pi RP2040 MCU. It is equipped with dual quadrature encoders for precise speed or position control, line sensors, front bump sensors, a comprehensive IMU (3-axis accelerometer, magnetometer, and gyro), six RGB LEDs, and a graphical OLED display. The Turtle Edition is assembled with 75:1 LP 6V Micro Metal Gearmotors, which contribute to an extended battery life. The robot's maximum speed is approximately 0.4 m/s, making it ideal for applications that require slow, controlled speed, such as coordinated swarm robots and introductory robotics courses.
The 3pi+ 2040 Robot is a versatile, high-performance, user-programmable robot with a diameter of just 9.7 cm (3.8 inch). It is powered by a Raspberry Pi RP2040 microcontroller, a 32-bit dual-core Arm Cortex-M0+ processor running at 125 MHz, which can be programmed with C++, Arduino, or Python. The robot comes with 16 MB (128 Mbit) of flash memory preloaded with a MicroPython interpreter, allowing immediate programming via its USB C port using the included example Python programs.
The 3pi+ 2040 Robot is equipped with two H-bridge motor drivers and a range of integrated sensors. These include 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 on the front face of the robot. The robot also features three onboard pushbuttons for user input, a 128x64 graphical OLED display, a buzzer, and six RGB LEDs for feedback.
The robot's unique power system maintains a constant 8 V for the motors, regardless of the battery charge level, ensuring that the speed of the motors remains consistent. The Turtle Edition of the 3pi+ 2040 Robot is assembled with 75:1 LP 6V Micro Metal Gearmotors, which have a lower top speed but allow for a longer battery life. This version is particularly suitable for applications that require slow, controlled speed, such as coordinated swarm robots and introductory robotics courses.
