Using ROS 2 with Connext

ROS 2 is based on the Data Distribution service (DDS) standard, already in use in thousands of critical applications worldwide. Although ROS 2 is designed to use DDS as its connectivity framework, the integration process has a few quirks that must be accommodated in order for a pure DDS system to seamlessly interoperate with a ROS 2 system.

What's Involved

This training will show you how to maximize the power of RTI Connext in your ROS 2 systems:

  • Understand how topic and types are managed in the rmw_connext_cpp layer
  • Using RTI’s tools and services ecosystem with ROS 2 applications
  • Creating a hybrid system to use the full capabilities of Connext beyond what ROS or ROS 2 alone can offer


The following criteria must be met before you can schedule this service:

  • You must have previous Connext experience and/or training. You must be familiar with the fundamental DDS concepts such as DDS entities, publish/subscribe APIs, Quality of Service configuration, discovery, transports, and configuration files.
  • You must be familiar with ROS 2 and its rmw layer

Expected Duration

We'll discuss your objectives to determine the effort required for this service.

Remote or Onsite
