Description

Overview

Early Adopter release:

We are initially offering the 3pi+ 2040 Robot as a limited release intended for advanced customers who have had some experience with robotics or Raspberry Pi RP2040 programming (e.g. with a Raspberry Pi Pico). The initial release is available with 30:1 MP motors (the “Standard Edition”), either assembled for 38% off or in kit form for 50% off. Early adopter robots will generally need to be backordered as they are built to order; we expect to ship within a business day of ordering. The robot hardware is finalized so the only changes we expect for the full product release are in the initial firmware configuration and pre-installed example programs. Documentation will also continue to be developed as we release the robot to a wider customer base.

Early adopters who publicly share their 3pi+ 2040 experiences will be eligible for an additional robot with an extra $25 discount.

The 3pi+ 2040 is a versatile, high-performance, user-programmable robot that measures just 9.7 cm (3.8″) in diameter. At its heart is a Raspberry Pi RP2040 microcontroller (like the one on the Raspberry Pi Pico), a 32-bit dual-core Arm Cortex-M0+ processor running at 125 MHz, which can be programmed with C, C++, Arduino, or Python. The 3pi+ 2040 has 16 MB (128 Mbit) of flash memory that ships preloaded with a MicroPython interpreter, so you can get started right away by plugging into its USB C port and editing the included example Python programs. For advanced users who want to customise or enhance their robots with additional peripherals, the robot’s power rails, power system controls, and microcontroller’s I/O lines can be accessed via several 0.1″-pitch expansion ports.

The 3pi+ (or 3𝜋+) 2040 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 downwards-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 128×64 graphical OLED display, buzzer, and six RGB 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+ 2040 robot is available as a kit or fully assembled:

3pi+ 2040 Version	Products	Micro Metal Gearmotor	Top Speed	Comments
Standard Edition	assembled or kit	30:1 MP 6V	1.5 m/s	good combination of speed and controllability

What else you will need

four AAA batteries: the 3pi+ robot works with both alkaline and NiMH batteries, though we recommend rechargeable NiMH cells
a USB C cable to connect the robot to your computer for programming and debugging

Assembling the kit version

The following video shows the steps to assemble a different version of the 3pi+ robot (the 3pi+ 32U4 OLED robot), but these steps generally remain the same for the 3pi+ 2040:
