R3Rx

R3Rx is a software framework designed to support real-time data processing and control in embedded and edge computing environments. It provides a modular runtime and a set of building blocks for data ingestion, streaming, event processing, state management, and decision making. The architecture centers on a lightweight core with a pluggable extension system, enabling developers to add sensors, actuators, and processing nodes without modifying the core software.

Communication in R3Rx is implemented through a publish-subscribe messaging layer with deterministic scheduling to meet real-time constraints. The framework supports cross-language bindings, allowing components to be written in languages such as Python, C++, and Rust while sharing a common data model and libraries. Emphasis is placed on portability across a range of devices, from microcontrollers to single-board computers, and on security features including authentication, authorization, and tamper-evident logging.

R3Rx originated as an open-source initiative intended to unify disparate real-time components used in robotics, industrial automation, and Internet of Things applications. It provides tooling for building, testing, and deploying configurations, as well as a catalog of reusable plugins and connectors to integrate with external systems and hardware.

Usage scenarios include autonomous drones, factory automation, and intelligent sensor networks where low latency and reliable state management are essential. Since its inception, the project has attracted community contributions and has been evaluated in benchmarks focusing on latency, throughput, and resilience. R3Rx aims to balance performance with developer productivity through high-level abstractions complemented by low-level controls when needed.
