New mapping/localization/navigation demos start with architect.</h2>\n<h1>Navigation</h1>\n<p>Treat Nav2 as a <strong>navigation chain</strong>. Find the first link whose evidence is\nwrong.</p>\n<h2>Start from the robot</h2>\n<ul>\n<li>For a new app or first demo, read <a href=\"../architect/SKILL.md\">architect</a> before\nscaffolding or installing a navigation stack. It finds the saved apps checkout\nand selects a compatible baseline, even from outside the Robium workspace.\nIf that selection already happened, continue here. Existing-app fixes and\nnavigation explanations do not need onboarding.</li>\n<li>Read the running system and its repository before proposing a new stack.</li>\n<li>Identify the ROS distribution, installed Nav2 version, launch topology, and\nparameter files from the environment itself.</li>\n<li>Note the robot's motion model, footprint, sensors, frames, command interface,\nand whether it is using SLAM or a saved map.</li>\n<li>Start from the robot vendor's matching configuration. Change only what the\napplication has outgrown.</li>\n</ul>\n<h2>Trace the chain</h2>\n<ul>\n<li><strong>Environment:</strong> the installed packages, launch files, parameters, and\nrunning graph describe the same stack.</li>\n<li><strong>Pose:</strong> clock and transforms are fresh; one localizer owns <code>map -&gt; odom</code>;\nodometry owns the path from <code>odom</code> to the robot base.</li>\n<li><strong>World:</strong> the map and live sensors reach both costmaps in frames they can\ntransform.</li>\n<li><strong>Plan:</strong> the navigation action accepts the goal and the planner produces a\npath in the intended frame.</li>\n<li><strong>Control:</strong> the controller receives that path and can produce a valid motion\ncommand for the robot's kinematics and footprint.</li>\n<li><strong>Base:</strong> command topic, message type, smoothing or safety nodes, and base\ndriver agree end to end.</li>\n<li>Change the first broken link, then re-check what depends on it.</li>\n</ul>\n<h2>Go deeper only when needed</h2>\n<ul>\n<li>If navigation is failing and the broken link is unclear, read\n<a href=\"FAILURES.md\">FAILURES.md</a>.</li>\n<li>If the stack is TurtleBot3 on ROS 2 Jazzy with Gazebo Harmonic, read\n<a href=\"TURTLEBOT3-JAZZY-GAZEBO.md\">TURTLEBOT3-JAZZY-GAZEBO.md</a> before changing its\nlaunch or parameters.</li>\n<li>For distribution-sensitive parameters, behavior trees, or custom Nav2\nplugins, inspect the matching installed source and current official Nav2\ndocumentation.</li>\n<li>Reach for ROS 2 guidance when the evidence points to discovery, QoS, TF, or\npackage wiring; Gazebo guidance for simulation, spawning, sensors, or\nbridges; and RViz2 or Foxglove guidance for viewer behavior.</li>\n</ul>\n<h2>Done</h2>\n<ul>\n<li>Verify the changed link and the user-visible outcome: the intended goal\ncompletes on the actual robot or representative simulation.</li>\n<li>If the chain cannot be completed, name the first unsupported link and the\nevidence still needed.</li>\n</ul>\n","files":[{"path":"evals.yaml","sizeBytes":370,"isText":true},{"path":"FAILURES.md","sizeBytes":3445,"isText":true},{"path":"SKILL.md","sizeBytes":2802,"isText":true},{"path":"TURTLEBOT3-JAZZY-GAZEBO.md","sizeBytes":4653,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
