RTI Introduces Enhanced ROS 2 Support to Accelerate Development of Scalable Robotics Systems

Application Developers Can Now Leverage Connext DDS Scalability and Productivity Tools With the ROS 2 Ecosystem

SUNNYVALE, Calif. – Nov. 10, 2020 – Real-Time Innovations (RTI)the largest software framework provider for smart machines and real-world systems, today announced the availability of the Connext 6 ROS Middleware Wrapper (RMW) Layer, bringing the field-proven, production-grade strength of RTI Connext® 6 to the latest release of the Robot Operating System (ROS 2). Robotics software developers can now leverage the ROS 2 ecosystem together with RTI Connext Tools to more rapidly develop, test and debug distributed robotics systems. RTI will showcase the new Connext RMW layer at ROS World on November 12.

ROS 2 offers an open-source framework for building robotic systems. RTI is the leading supplier of software compliant with the Data Distribution Service™ (DDS) standard, which provides the connectivity backbone for ROS 2. The new Connext 6 RMW layer now provides a best-of-both-worlds solution by connecting the ROS 2 ecosystem with RTI’s latest software and Connext Tools.

"RTI was founded out of the Stanford Robotics lab so robotics is deeply rooted in our DNA," said Gerardo Pardo-Castellote, CTO at RTI. "We work with our customers beginning in the research phase of their system development all the way through to production where performance, reliability and scalability become critical. We recognize the value of participating in the ROS ecosystem and are proud to offer new ways to utilize RTI Connext DDS for a production-grade solution."

The new Connext RMW layer offers:

  • The flexibility of the ROS 2 platform combined with complete access to RTI Connext tools for improved distributed system visualization and debugging capabilities
  • Support for RTI Connext DDS Professional in Connext 6, used for industrial and military robotics applications where reliability and scalability are of paramount importance
  • Support for RTI Connext DDS Micro
  • Support for future releases of the Connext Product Suite

"We developed the new Connext RMW layer from the ground up to better take advantage of Connext APIs and features," said Andrea Sorbini, Senior Software Engineer at RTI and technical lead for the project. "This allowed us to simplify the code and greatly improve the performance of the RMW layer, while also providing more turnkey access to RTI’s powerful distributed system development tools."

"The new RMW brings the system-level visibility and monitoring capabilities of Connext DDS to ROS 2," said Neil Puthuff, Senior Software Integration Engineer at RTI. "It enables advanced tools, such as RTI Admin Console and RTI Monitor to work seamlessly in a ROS 2 environment. No other current RMW offers this level of visibility and we look forward to continuing to help our customers simplify complex system development."

RTI in Robotics
RTI delivers the connectivity framework for safe, secure, reliable operations in complex, cooperative and autonomous robotics systems. RTI’s software is proven in robotics systems around the world including automotive, medical, manufacturing, aerospace & defense, and more.

RTI Connext DDS is active in over 250 autonomous vehicle projects and more than 50 commercial autonomous systems, such as Aptiv, Baidu Apollo, Voyage and Xpeng Motors. In June 2020, RTI joined the Autoware Foundation, an open alliance for autonomous driving technology, where RTI is leveraging its experience with ROS 2 to help advance the foundation's Autoware.IO and Autoware.Auto initiatives. RTI is the only DDS vendor to be named an AUTOSAR Development Partner and contributes to the development of the AUTOSAR standard for highly autonomous vehicles.

RTI Connext DDS can also be found at the core of NASA's rovers and space robots, leveraged by the European Space Agency’s robotic arm, and implemented in TechnipFMC’s semi-autonomous underwater ROVs. It is also widely used in building and running robotics projects in leading universities around the world. More recently, RTI Connext DDS was used by the collegiate teams entered in the Indy Autonomous Challenge (IAC) as they participated in the September hackathon, one of several leading up to the IAC final race at the Indianapolis Motor Speedway on October 23, 2021.

RTI will be showcasing the Connext RMW Layer at ROSWorld 2020 on November 12 in RTI's virtual booth here. For more information and to register, please visit:
