micro-ROS represents one of four exclusive elements of Vulcanexus, the all-in-one ROS 2 tool set. Vulcanexus offers free Dockers for Humble and Iron. Developed an new feature or found a bug? We answer both Github pull requests and issues. Book chapter. The chapter 'Micro-ROS' in Volume 7 of Springer's ROS Book Series

Micro-ROS aims to bring ROS 2 to a wide set of microcontrollers to allow having first-class ROS 2 entities in the embedded world. The main targets of micro-ROS are mid-range 32-bits microcontroller families.

This chapter provides a number of tutorials to learn micro-ROS and relevant tools for the different RTOSes supported by micro-ROS. If you are new to micro-ROS, we strongly suggest that you take the tutorials in the following order: First micro-ROS application on Linux. This tutorial teaches you how to install the micro-ROS framework and tools.

Micro-ROS is made up of well-established components: Famous open-source RTOSs, a standardized middleware, and the standard ROS 2 Client Support Library (rcl). In this way, the amount of micro-ROS-specific code was minimized for long-term maintainability.

In the follow-up tutorial First micro-ROS application on an RTOS, you’ll learn how to build and bring this application on a microcontroller running the RTOS NuttX, FreeRTOS, or Zephyr. Finally, in the tutorial Zephyr Emulator you’ll learn how to test a micro-ROS application on a Zephyr emulator. Installing ROS 2 and the micro-ROS build system

To date, micro-ROS is supported by the RTOSes FreeRTOS, Zephyr, NuttX, in addition to Linux and Windows. All three RTOSes are downloaded natively with the micro-ROS build system , and can be chosen when creating a new firmware workspace.

In addition to the above entry-level tutorials, we created a collection of demos that showcase micro-ROS in real applications which are easy to reproduce by the community — and thus you. Unlike tutorials, we do not explain the demo code step by step, but provide ready-to-use Docker files to get you started as quickly as possible.

The Client Library provides the micro-ROS API for the user code, i.e., for application-level micro-ROS nodes. The goal is to provide all relevant, major ROS 2 concepts in an optimized implementation for microcontrollers.

In this tutorial you will learn how to connect Teensy with micro-ROS and ROS 2. You will also learn how to install micro-ROS agent in Linux systems to communicate with Teensy-based Arduino board using Arduino IDE. This tutorial will also cover a simple publisher topic published from teensy and subscribed using ROS 2 interface. Target platform

Aug 27, 2020 · micro-ROS targets mid-range and medium-to-high performance 32-bits microcontrollers families. Up to now, the boards officially supported by the project were solely based on the STM32 series from ST, MCUs featuring ARM Cortex-M processors.
