Orocos RTT / ROS Integration Packages

Build Status

Introduction

This repository contains ROS 2 packages necessary for building Orocos Real-Time Toolkit (RTT) libraries, plugins, and components to communicate with ROS 2 nodes and to integrate with higher-level ROS concepts.

Packages

The packages in this repository provide:

  • rtt_ros2 CMake helpers, scripts and launch files to find and use Orocos RTT and OCL in an ament_cmake package and an RTT service plugin to find and import those packages into Orocos.

  • rtt_ros2_idl Generate RTT typekits from ROS 2 message and service definitions specified in the ROS interface definition language (IDL).

  • rtt_ros2_node Instantiate a per-process or per-component ROS 2 node from within an Orocos deployment.

  • rtt_ros2_topics Connect Orocos ports to ROS 2 topics for real-time safe inter-process communication.

  • rtt_ros2_services Provide ROS 2 services that call Orocos operations or connect Orocos operation callers to ROS services provided by other nodes.

  • rtt_ros2_interfaces provides a convenience macro that generates typekits and Orocos plugins for a given ROS 2 interface package, using all of the packages above.

    To a generate a typekit, run the command

    ros2 run rtt_ros2_interfaces create_typekit_package [PACKAGE]
    

    Where package is the package containing the messages or services.

  • rtt_ros2_params Provides ROS 2 parameters interface to manipulate parameters as in ROS 2 parameters and load/store them from/to Orocos properties.
