bridge_rest

RESTful HATEOAS bridge for robotkernel-hal

bridge_rest exposes the internal services of robotkernel-hal as a RESTful web service using JSON payloads. It enables read and write access (e.g., CANopen, EtherCAT) via HTTP, facilitating integration with web-based frontends or remote systems.

This bridge follows REST and HATEOAS principles and is designed to be lightweight, real-time-friendly, and embeddable.
