navigation skillA
navigation is agent-read markdown (skill) from robium-ai/robium: Configure, extend, and debug Nav2 in an existing robot app; explain navigation concepts. New mapping/localization/navigation demos start with architect..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Navigation Treat Nav2 as a **navigation chain**. Find the first link whose evidence is wrong. ## Start from the robot - For a new app or first demo, read [architect](../architect/SKILL.md) before scaffolding or installing a navigation stack. It finds the saved apps checkout and selects a compatible baseline, even from outside the Robium workspace. If that selection already happened, continue here. Existing-app fixes and navigation explanations do not need onboarding. - Read the running system and its repository before proposing a new stack. - Identify the ROS distribution, installed Nav2 version, launch topology, and parameter files from the environment itself. - Note the robot's motion model, footprint, sensors, frames, command interface, and whether it is using SLAM or a saved map. - Start from the robot vendor's matching configuration. Change only what the application has outgrown. ## Trace the chain - **Environment:** the installed packages, launch files, parameters, and running graph describe the same stack. - **Pose:** clock and transforms are fresh; one localizer owns `map -> odom`; odometry owns the path from `odom` to the robot base. …

How to install
mdr add robium-ai/robium/navigation@git:20260919.498ea4emdr add robium-ai/robium/navigation@sha256:a564d79aeba64c33Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
