Nav11Nav19

Nav11Nav19 is a modular navigation framework used in autonomous systems to coordinate planning, mapping, and localization. The name denotes the integration of two subcomponents, Nav11 and Nav19, operating in concert to provide robust navigation across changing environments.

Nav11 is a high-level planning module that leverages grid-based maps and abstract representations to generate feasible routes, taking into account dynamic obstacles, no-go zones, and efficiency metrics. It can adapt its plan at low latency to reflect changes in the environment.

Nav19 is a localization and sensor-fusion module that estimates the agent's pose and map consistency using probabilistic filters, feature matching, and simultaneous localization and mapping techniques. It tolerates sensor dropout and drift, providing updated poses to the planner.

Data exchange between Nav11 and Nav19 is designed to be bidirectional: Nav11 can request updated localization data to replan, while Nav19 can supply confidence levels and map updates to influence planning decisions.

Applications include autonomous vehicles, aerial drones, warehouse robotics, and research platforms. The framework supports multiple sensors and can be implemented within common robotics middleware, enabling experiments in mixed-reality and simulation environments.

In practice, Nav11Nav19 acts as a conceptual architecture rather than a single released system. Real-world deployments often implement Nav11 and Nav19 as separate modules with varying interfaces, requiring careful synchronization and fault handling to maintain reliability.
