README.md

The rcl_executor repository

This repository contains executors developed in the micro-ROS project for real-time execution.

In detail, this repository contains two ROS packages:

  • rcl_executor provides an executor that works directly based on the ROS 2 Client Support Library (rcl)
  • rcl_executor_examples provides small examples for the use of rcl_executor.

Technical information on the interfaces and use of these packages is given in the README.md files in the corresponding subfolders.

Purpose of the project

The software is not ready for production use. It has neither been developed nor tested for a specific use case. However, the license conditions of the applicable Open Source licenses allow you to adapt the software to your needs. Before using it in a safety relevant setting, make sure that the software fulfills your requirements and adjust it according to any applicable safety standards (e.g. ISO 26262).

Requirements, how to build, test, install, use, etc.

Clone the repository into a ROS workspace and build it using colcon.

License

rcl_executor is open-sourced under the Apache-2.0 license. See the LICENSE file for details.

For a list of other open source components included in rcl_executor, see the file 3rd-party-licenses.txt.

Quality assurance

The colcon_test tool is used for quality assurances, which includes cpplint, uncrustify, flake8, xmllint and various other tools.

Unit tests based on gtest are located in the rcl_executor/test folder.

Known issues/limitations

Please notice the following issues/limitations:

  • rcl_executor only supports the ROS handle types subscriptions and timers. Other handle types, namely guard_conditions, services and clients are not supported.
You can’t perform that action at this time.
