mros2

mros2 (formally mROS 2) realizes an agent-less and lightweight runtime environment compatible with ROS 2 for embedded devices. It consists of basic APIs for pub/sub communication, RTPS protocol, UDP/IP stack, and real-time kernel. Embedded nodes can now communicate directly with native ROS 2 nodes via topic!

This repository maintains the communication layer of mROS 2, that mainly offers pub/sub APIs compatible with rclcpp for embedded devices. ROS 2 is a de-fact platform for the robot system development, and provides pub/sub communication infrastructure with the DDS/RTPS protocol.

Features

  • Agent-less: a node on mROS 2 autonomously discovers communication nodes on the host with the feature of embeddedRTPS. It means no agent/bridge is required for pub/sub communication from the embedded devices.
  • Lightweight: mROS 2 APIs are implemented by C++ to be operated on the embedded devices. All software stacks are also implemented only in C/C++.
  • Real-time: mROS 2 employs the real-time kernel (e.g., TOPPERS kernel) as the runtime platform in order to enhance the real-time capability.

Functionalities and limitations

Here are functionalities that mROS 2 offers for you, and current limitations (a.k.a call for your contibutions!).

  • Pub/Sub communication via Topic is supported
  • Service, Actions, and Parameters are not supported
    • Please let us know if you want to use them as soon as possible. We can consider of raising the priority of these supports.

Supported platform

Since this repository itself only maintains the communication layer of mROS 2, we also publish the implementation on the embedded board using this layer and the embedded kernel. Please see each repository to learn how to use it.

name kernel board
mros2-asp3-f767zi TOPPERS/ASP3 STM32 NUCLEO-F767ZI
mros2-mbed Mbed OS 6 Mbed enabled boards having an Ethernet port (See detail)

Please let us know if you have a request for a support of board/kernel, or if you could implement this layer on another platform.
