ROS-core implementation in Rust

Rust License Rust CI

This Rust library provides a standalone implementation of the ROS (Robot Operating System) core. It allows you to run a ROS master and communicate with other ROS nodes without relying on an external ROS installation. You can use this library to build ROS nodes entirely in Rust, including publishers and subscribers, without needing to use any other ROS dependencies.


Standalone ROS core

To start the ROS core, run the following command:

# start the ros-core
RUST_LOG=debug cargo run

And run any of your ROS stack, eg., the python chatter example.


This example creates a single binary which contains:

  • ROS core
  • ROS publisher
  • ROS subscriber

To run the talker/listener example, execute the following command:

RUST_LOG=info ROSRUST_MSG_PATH=`realpath examples/chatter/msgs` cargo run --example chatter --release
# Stop by Ctrl+C and Ctrl+Z
kill -9 %1

This example creates a single binary that includes a standalone implementation of the ROS core, as well as a ROS publisher and ROS subscriber. This implementation is inspired by the official chatter python example from the ROS wiki, which demonstrates a simple communication between two nodes using ROS messages. You can stop the program by using Ctrl+C and Ctrl+Z.

Debugging with official ROS docker image

To showcase that this ROS core implementation can be used with official ROS publishers and subscribers in Python, we have provided a debugging script that launches a ROS Docker image and runs a talker and listener example. To run the script, execute the following commands:

# change directory to debugging folder
cd debugging
# make the script executable
chmod +x run.sh
# execute the script

This script will download the official ROS Docker image and launch a container with a ROS environment. Then, it will run a Python script that uses the ROS talker and listener nodes to communicate with the standalone ROS core implementation from this repository. This is intended as an example of how to use the standalone ROS core (ros-core-rs) implementation with other ROS nodes, but it is not necessary to use this script to use the standalone implementation on its own.
