Bazel rules for ROS 2

This repo provides functionality to build and use ROS 2 with Bazel.

You will need to install Bazel, see here. Besides Bazel, you will need a C++ compiler and a Python 3 interpreter.

And no, you don't have to install any ROS 2 packages via apt.

The code is developed and tested on Ubuntu 22.04 with Python 3.10.

Available features:

• Building of C++, Python and Rust nodes.
• C/C++/Python/Rust code generation for interfaces (messages, services and actions).
• Defining ROS 2 deployments with ros2_launch Bazel macro.
• Defining ROS 2 tests with ros2_test Bazel macro.
• Defining ROS 2 plugins with ros2_plugin Bazel macro.
• Only CycloneDDS middleware can be used at the moment.
  • Zero copy transport via shared memory backend (iceoryx) for CycloneDDS.
• Logging backends:
  • spdlog (default): --@com_github_mvukov_rules_ros2//ros2:rcl_logging_impl=spdlog
  • syslog: --@com_github_mvukov_rules_ros2//ros2:rcl_logging_impl=syslog
• Utilities:
  • foxglove_bridge for visualization and debugging
  • ros2_bag for handling rosbags
  • ros2_lifecycle for handling node lifecycle
  • ros2_node for handling nodes
  • ros2_param for handling parameters
  • ros2_service for handling services
  • ros2_topic for handling topics
  • xacro for Xacro to URDF conversion

Please take a look at the examples folder to get started.

ROS 2 packages are by default locked to versions from release-humble-20250721.

• RobotLocomotion/drake-ros/bazel_ros2_rules, which includes a brief analysis of this and other approaches.
