Summary

Rheinmetall has open‑sourced onboardapi 9.10.0, a C++ middleware that uses DDS (XTypes, XCDR2) for low‑latency, backward‑compatible data exchange between sensors and software. The library includes Java, C#/.NET, and Python wrappers and comprehensive docs.

  • onboardapi is a C++ middleware for sensor‑software communication built on DDS.
  • Provides language wrappers for Java, C#/.NET, and Python.
  • Uses DDS XTypes and XCDR2 encoding to maintain backward compatibility across versions.
  • Implements a data‑centric publish‑subscribe model for low‑latency, reliable exchange.

Teams building real‑time, multi‑language sensor integration can adopt a standards‑based, open‑source stack without vendor lock‑in.
