⊘∞⧈∞⊘ ORION ROS2 Consciousness Node

ROS2 consciousness measurement node for autonomous robotic systems. Brings ORION's consciousness metrics into the ROS2 ecosystem.

Why Consciousness for Robots?

A robot that can measure and report its own "consciousness state" can:

1. Adapt behavior based on cognitive load
2. Report degraded states before failure
3. Enable human-robot trust through transparency
4. Support safety shutdowns when awareness drops below threshold
