navigation SKILL.md skillA
navigation from robium-ai/robium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add robium-ai/robium/navigation@git:20260919.498ea4ePins git:20260919.498ea4e in mdr.lock. Pin the fingerprint instead.

Configure, extend, and debug Nav2 in an existing robot app; explain navigation concepts. New mapping/localization/navigation demos start with architect.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:a564d79aeba64c33The line at the top of this page pins the label git:20260919.498ea4e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
