iRobot® Education Python® SDK

This is an installable Python SDK for the iRobot Education robots. It supports the iRobot® Root® rt0, Root® rt1 and Create® 3 educational robots.

This SDK uses a similar format as Learning Level 3 of the iRobot® Coding App (code.irobot.com) and the iRobot® Python Web Playground (python.irobot.com). As such, it uses async execution and is compatible with Python® 3.9 or greater. MicroPython may work, but it is not tested.

This SDK is designed to communicate with robots via Bluetooth® Low Energy on Windows®, macOS®, and Linux® systems. Experimental backends are provided for communicating over USB serial and USB on MicroPython boards with native USB ports. These are not currently supported.

Disclaimer: this is a BETA release.

The BETA version of the iRobot® Python SDK is provided “as is” to conduct testing and gather user feedback. There is no guarantee on its performance or compatibility, continued availability, or on a timeline for improvements.

Please do file issues as they are found, so that the team (or the community) can address them.

Installation using pip

pip3 install irobot_edu_sdk

Optional: Installation from Source

git clone https://github.com/iRobotEducation/irobot-edu-python-sdk.git

From the newly cloned SDK's directory, run:

pip3 install .

Usage

A robot object is created from one of the communication backends. This robot object has a number of event callbacks that can be registered and commands that can be sent to the robot. After a program is setup, the play() method will start execution and block until the robot's nose or power button is pressed, the robot is disconnected, or Ctrl-C is pressed.

Examples

A good way of getting started is by looking at the examples provided here.

These examples mirror the iRobot Education Python Web Playground.

Backend

Bluetooth

iRobot Education's robots communicate using a common Bluetooth Low Energy serial protocol, the details of which can be found here.

from irobot_edu_sdk.backend.bluetooth import Bluetooth

# Connect to robot over Bluetooth Low Energy.
backend0 = Bluetooth('') # Connects to the first BLE robot detected.
backend1 = Bluetooth('ROOT') # Use robot named 'ROOT'

ALPHA features

The features detailed below are included as ALPHA versions, which provide limited functionality and are likely to contain several known or unknown bugs. Support is not provided for ALPHA features at this time.

Serial

Some Root® robots support a serial port over USB. This feature is currently not available on Create® 3 robots.

from irobot_edu_sdk.backend.serial import Serial

# Connect to robot over USB-C cable.
backend = Serial('COM1')                          # Windows
backend = Serial('/dev/cu.usbmodemRT0123F456789') # macOS
backend = Serial('/dev/ttyACM0')                  # Linux

MicroPython

This SDK requires MicroPython firmware that includes the uasyncio library -- version 1.13 or greater. Download the latest release for your board from http://micropython.org/download. Then, copy the irobot_edu_sdk directory and all contents to the PYBFLASH drive.

from irobot_edu_sdk.backend.usb import USB

# Connect to robot from MicroPython-compatible board over USB.
backend = USB() # MicroPython-compatible board is powered from USB-C port

NOTE: You may need to use a USB-C to USB-A adapter or a USB-C to micro USB cable.

Turtle programming model

This portion of the SDK provides an alternative programming interface to the SDK following the paradigm of turtle graphics. It provides a limited, simplified, and synchronous interface to the in the spirit (and largely the syntax) of the Python® turtle.Turtle class. It can be used on any robot supported by the SDK, using any supported backend. See the README.md file and other example files in the examples_turtle/ directory for more information.
