micro_ros_arduino
A micro-ROS library for Arduino IDE and CLI, enabling ROS 2 communication on embedded microcontrollers.
What is micro_ros_arduino?
micro-ROS for Arduino is a library that enables Arduino-compatible microcontrollers to run micro-ROS, a lightweight version of ROS 2 designed for embedded systems. It solves the problem of integrating low-resource devices into ROS 2 networks by providing precompiled binaries and tools for custom builds. This allows developers to leverage ROS 2's communication capabilities on hardware like ESP32, Teensy, and Arduino boards.
Robotics developers and embedded systems engineers working with Arduino-based microcontrollers who need to integrate their devices into ROS 2 ecosystems. It's particularly useful for those building distributed robotic systems or IoT applications requiring standardized communication.
Developers choose micro-ROS for Arduino because it dramatically simplifies adding ROS 2 support to embedded projects—avoiding the complexity of building micro-ROS from scratch. Its precompiled libraries reduce setup time, while the option to customize builds offers flexibility for specific needs.
Overview
micro-ROS library for Arduino
Use Cases
Best For
- Adding ROS 2 communication to Arduino-based robotic peripherals
- Integrating microcontrollers into existing ROS 2 networks
- Prototyping distributed robotic systems with embedded sensors/actuators
- Educational projects teaching ROS 2 on accessible hardware
- Building IoT devices that need to communicate with ROS 2 systems
- Creating custom message types for microcontroller-ROS 2 interactions
Not Ideal For
- Production deployments requiring safety certifications like ISO 26262
- Systems needing wireless or Ethernet communication without custom transport development
- Teams committed to PlatformIO for microcontroller development
Pros & Cons
Pros
Provides ready-to-use libraries for Arduino IDE, allowing quick integration without complex builds, as shown in the download and include instructions for sketches.
Supports a wide range of boards from official ones like Portenta H7 to community-contributed ones like Raspberry Pi Pico, detailed in the comprehensive supported boards table.
Enables rebuilding with Docker to customize micro-ROS configuration, add packages, or modify message types via the extras/library_generation folder, offering flexibility for advanced needs.
Includes a Docker command to run a micro-ROS agent with serial transport, reducing setup overhead for connecting to ROS 2 networks, as outlined in the usage examples.
Cons
Only USB serial transport is provided, and the README admits that transports need refactoring for pluggable mechanisms, restricting communication options without custom development.
Requires patching platform.txt files for boards like Teensy and SAM, adding extra setup steps and potential for configuration errors, as detailed in the patching sections.
Explicitly stated in the 'Purpose of the Project' as not ready for production use, lacking testing for specific use cases and requiring additional safety validation.
