RE2 plans to integrate its JAUS (Joint Architecture for Unmanned Systems) software development kit with RTI's data distributing middleware product. The effort aims to enable the use of RTI's Data Distribution Service (DDS) middleware in unmanned systems that are required by the U.S. Department of Defense to comply with JAUS.

RTI's DDS, formerly NDDS (Network Data Distribution Services), is described as an implementation of the Object Management Group's Data Distribution Service for Real-time Systems. It implements a real-time publish-subscribe communications model with C, C++, and Java interfaces, and allows distributed processes to share data without concern for physical location or network architecture, RE2 says.

RE2's JAUS software development kit (SDK) supports Linux, QNX, VxWorks, Windows, and MacOS. It comprises configurable binaries that route JAUS traffic, along with libraries exposing C/C++ APIs. RE2 says integrating its kit with DDS will provide "a scalable platform that isolates the software implementation from the hardware architecture and underlying communications mechanisms."

David Barnett, VP of product management at RTI, stated, "By creating a JAUS wrapper around the RTI Data Distribution Service, we will provide our customers specializing in unmanned systems and robotics with a robust JAUS-compliant middleware solution to ensure that they meet the Department of Defense (DoD) JAUS mandate."

Chris Lanfear, director of the embedded software group at VDC, stated, "From underwater and sea-surface robotics to military tactical communications to advanced warning and control systems, JAUS-compliant systems are essential for moving the entire unmanned systems market forward."

RTI sold its ScopeTools embedded development tools business to Wind River in January of last year, saying at the time that it intended to focus on its (N)DDS middleware. RTI originally spun out in 1991 from Stanford University's robotics research group.
