luos

Luos is an open-source software framework and protocol for modular, distributed embedded systems. It enables dynamic composition of device functionality through microservice-like software components called containers. Developed by Luos Technologies, Luos is used to connect sensors, actuators, and controllers across embedded networks, promoting flexibility and scalability in complex hardware systems.

The architecture centers on nodes and containers. A node is a microcontroller or embedded device running Luos OS, hosting one or more containers. Each container implements a distinct service and exposes a defined interface. Containers communicate by sending messages over a Luos network, which is transport-agnostic and can operate over physical layers such as CAN, UART, I2C, or Ethernet. The Luos protocol provides automatic service discovery, address routing, and support for remote procedure calls and event messages.

Developers implement containers in C or C++ using the Luos SDK, and deploy them to devices running Luos OS. The runtime handles message routing, service identification, and error handling, enabling new containers to be added or updated with minimal disruption. This modular approach helps decouple software from hardware, simplifies system integration, and supports scalable architectures.

Common applications include robotics, automotive electronics, and industrial automation, where Luos helps manage modular sensors, actuators, and control software. The project emphasizes openness, reusability, and interoperability across hardware platforms, fostering a community of hardware targets, containers, and development tools.
